One of the few native campanulas, the TALL BELLFLOWER (C. Americana), waves long, slender wands studded with blue or sometimes whitish flowers high above the ground of moist thickets and woods throughout the eastern half of this country, but rarely near the sea. Doubtless the salt air, which intensifies the color of so many flowers, would brighten its rather slatey blue. The corolla, which is flat, round, about an inch across, and deeply cleft into five pointed petals, has the effect of a miniature pinwheel in motion. Mature flowers have the style elongated, bent downward, then curved upward, that the stigmas may certainly be in the way of the visiting insect pollen-laden from an earlier bloomer, and be cross-fertilized. The larger bees, its benefactors, which visit it for nectar, touch only the upper side of the style, on which they must alight; but the anthers waste pollen by shedding it on all sides. No insect can take shelter from rain or pass the night in this flower, as he frequently does in its more hospitable relative, the harebell. English gardeners, more appreciative than our own of our native flora, frequently utilize this charming plant in their rockwork, increasing their stock by a division of the dense, leafy rosettes.
VENUS' LOOKING-GLASS; CLASPING BELLFLOWER (Legouzia perfoliata; Specularia perfoliata of Gray) Bellflower family
Flowers - Violet blue, from 1/2 to 3/4 in. across; solitary or 2 or 3 together, seated, in axils of upper leaves. Calyx lobes varying from 3 to 5 in earlier and later flowers, acute, rigid; corolla a 5-spoked wheel; 5 stamens; pistil with 3 stigmas. Stem: 6 in. to 2 ft. long, hairy, densely leafy, slender, weak. Leaves: Round, clasped about stem by heart-shaped base. Preferred Habitat - Sterile waste places, dry woods. Flowering Season - May-September. Distribution - From British Columbia, Oregon, and Mexico, east to Atlantic Ocean.
At the top of a gradually lengthened and apparently overburdened leafy stalk, weakly leaning upon surrounding vegetation, a few perfect blossoms spread their violet wheels, while below them insignificant earlier flowers, which, although they have never opened, nor reared their heads above the hollows of the little shell-like leaves where they lie secluded, have, nevertheless, been producing seed without imported pollen while their showy sisters slept. But the later blooms, by attracting insects, set cross-fertilized seed to counteract any evil tendencies that might weaken the species if it depended upon self-fertilization only. When the European Venus' looking-glass used to be cultivated in gardens here, our grandmothers tell us it was altogether too prolific, crowding out of existence its less fruitful, but more lovely, neighbors.
The SMALL VENUS' LOOKING-GLASS (L. biflora), of similar habit to the preceding, but with egg-shaped or oblong leaves seated on, not clasping, its smooth and very slender stem, grows in the South and westward to California.
GREAT LOBELIA; BLUE CARDINAL-FLOWER (Lobelia syphilitica) Bellflower family
Flowers - Bright blue, touched with white, fading to pale blue, about 1 in. long, borne on tall, erect, leafy spike. Calyx 5-parted, the lobes sharply cut, hairy. Corolla tubular, open to base on one side, 2-lipped, irregularly 5-lobed, the petals pronounced at maturity only. Stamens 5, united by their hairy anthers into a tube around the style; larger anthers smooth. Stem: 1 to 3 ft. high, stout, simple, leafy, slightly hairy. Leaves: Alternate, oblong, tapering, pointed, irregularly toothed, 2 to 6 in. long, 1/2 to 2 in. wide. Preferred Habitat - Moist or wet soil; beside streams. Flowering Season - July-October Distribution - Ontario and northern United States west to Dakota, south to Kansas and Georgia.
To the evolutionist, ever on the lookout for connecting links, the lobelias form an interesting group, because their corolla, slit down the upper side and somewhat flattened, shows the beginning of the tendency toward the strap or ray flowers that are nearly confined to the composites of much later development, of course, than tubular single blossoms. Next to massing their flowers in showy heads, as the composites do, the lobelias have the almost equally advantageous plan of crowding theirs along a stem so as to make a conspicuous advertisement to attract the passing bee and to offer him the special inducement of numerous feeding places close together.
The handsome GREAT LOBELIA, constantly and invidiously compared with its gorgeous sister the cardinal flower, suffers unfairly. When asked what his favorite color was, Eugene Field replied: "Why, I like any color at all so long as it's red!" Most men, at least, agree with him, and certainly hummingbirds do; our scarcity of red flowers being due, we must believe, to the scarcity of hummingbirds, which chiefly fertilize them. But how bees love the blue blossoms!
There are many cases where the pistil of a flower necessarily comes in contact with its own pollen, yet fertilization does not take place, however improbable this may appear. Most orchids, for example, are not susceptible to their own pollen. It would seem as if our lobelia, in elevating its stigma through the ring formed by the united anthers, must come in contact with some of the pollen they have previously discharged from their tips, not only on the bumblebee that shakes it out of them when he jars the flower, but also within the tube. But when the anthers are mature, the two lobes of the still immature stigma are pressed together, and cannot be fertilized. Nevertheless, the hairy tips of some of the anthers brush off the pollen grains that may have lodged on the stigma as it passes through the ring in its ascent, thus making surety doubly sure. Only after the stigma projects beyond the ring of anthers does it expand its lobes, which are now ready to receive pollen brought from another later flower by the incoming bumblebee to which it is adapted.
Linnaeus named this group of plants for Matthias de l'Obel, a Flemish botanist, or herbalist more likely, who became physician to James I. of England.
Preferably in dry, sandy soil or in meadows, and over a wide range, the slender, straight shoots of PALE SPIKED LOBELIA (L. spicata) bloom early and throughout the summer months, the inflorescence itself sometimes reaching a height of two feet. At the base of the plant there is usually a tuft of bry oblong leaves; those higher up narrow first into spoon-shaped, then into pointed, bracts, along the thick and gradually lengthened spike of scattered bloom. The flowers are oft en pale enough to be called white. Like their relatives, they first ripen their anthers to prevent self-fertilization.
The lithe, graceful little BROOK LOBELIA (L. Kalmii), whose light-blue flowers, at the end of thread-like footstems, form a loose raceme, sways with a company of its fellows among the grass on wet banks, beside meadow runnels and brooks, particularly in limestone soil, from Nova Scotia to the Northwest Territory and southward to New Jersey. It bears an insignificant capsule, not inflated like the Indian tobacco's; and long, narrow, spoon-shaped leaves. Twenty inches is the greatest height this little plant may hope to attain.
Not only beside water, and in it, but often totally immersed, grows the WATER LOBELIA or GLADIOLE (L. Dortmanna). The slender, hollow, smooth stem rises from a submerged tuft of round, hollow, fleshy leaves longitudinally divided by a partition, and bears at the top a scattered array of pale-blue flowers from August to September.
INDIAN or WILD TOBACCO; GAG-ROOT; ASTHMA-WEED; BLADDER-POD LOBELIA (Lobelia inflata) Bellflower family
Flowers - Pale blue or violet, small, borne at short intervals in spike-like leafy racemes. Calyx 5-parted, its awl-shaped lobes 1/4 in. long, or as long as the tubular, 2-lipped, 5-cleft, corolla that opens to base of tube on upper side. Stamens, 5 united by their hairy anthers into a ring around the 2-lobed style. Stem: From 1 to 3 feet high, hairy, very acrid, much branched, leafy. Leaves: Alternate, oblong or ovate, toothed, the upper ones acute, seated on stem; lower ones obtuse, petioled, to 2 1/2 in. long. Fruit: A much inflated, rounded, ribbed, many seeded capsule. Preferred Habitat - Dry fields and thickets; poor soil. Flowering Season - July-November. Distribution - Labrador westward to the Missouri River, south to Arkansas and Georgia.
The most stupid of the lower animals knows enough to let this poisonous, acrid plant alone; but not so man, who formerly made a quack medicine from it in the days when a drug that set one's internal organism on fire was supposed to be especially beneficial. One taste of the plant gives a realizing sense of its value as an emetic. How the red man enjoyed smoking and chewing the bitter leaves, except for the drowsiness that followed, is a mystery.
On account of the smallness of its flowers and their scantiness, the Indian tobacco is perhaps the least attractive of the lobelias, none of which has so inflated a seed vessel, the distinguishing characteristic of this common plant.
CHICORY; SUCCORY; BLUE SAILORS; BUNK (Cichorium Intybus) Chicory family
Flower-head - Bright, deep azure to gray blue, rarely pinkish or white, 1 to 1 1/2 in. br set close to stem, often in small clusters for nearly the entire length; each head a composite of ray flowers only, 5-toothed at upper edge, and set in a flat green receptacle. Stem: Rigid, branching, to 3 ft. high. Leaves: Lower ones spreading on ground, 3 to 6 in. long, spatulate, with deeply cut or irregular edges, narrowed into petioles, from a deep tap-root; upper leaves of stem and branches minute, bract-like. Preferred Habitat - Rides, waste places, fields. Flowering Season - July-October. Distribuition - Common in Eastern United States and Canada, south to the Carolinas; also sparingly westward to Nebraska.
At least the dried and ground root of this European invader is known to hosts of people who buy it undisguised or not, according as they count it an improvement to their coffee or a disagreeable adulterant. So great is the demand for chicory that, notwithstanding its cheapness, it is often in its turn adulterated with roasted wheat, rye, acorns, and carrots. Forced and blanched in a warm, dark place, the bitter leaves find a ready market as a salad known as "barbe de Capucin" by the fanciful French. Endive and dandelion, the chicory's relatives, appear on the table too, in spring, where people have learned the possibilities of salads, as they certainly have in Europe.
From the depth to which the tap-root penetrates, it is not unlikely the succory derived its name from the Latin succurrere = to run under. The Arabic name chicourey testifies to the almost universal influence of Arabian physicians and writers in Europe after the Conquest. As chicoree, achicoria, chicoria, cicorea, chicorie, cichorei, cikorie, tsikorei, and cicorie the plant is known respectively to the French, Spanish, Portuguese, Italians, Germans, Dutch, Swedes, Russians, and Danes.
On cloudy days or in the morning only throughout midsummer the "peasant posy" opens its "dear blue eyes"
"Where tired feet Toil to and fro; Where flaunting Sin May see thy heavenly hue, Or weary Sorrow look from thee Toward a tenderer blue!" - Margaret Deland.
In his "Humble Bee" Emerson, too, sees only beauty in the "Succory to match the sky;" but, mirabile dictu, Vergil, rarely caught in a prosaic, practical mood, wrote, "And spreading succ'ry chokes the rising field."
IRON-WEED; FLAT TOP (Vernonia Noveboracensis) Thistle family.
Flower-head - Composite of tubular florets only, intense reddish-purple thistle-like heads, borne on short, branched peduncles and forming br flat clusters; bracts of involucre, brownish purple, tipped with awl-shaped bristles. Stem: 3 to 9 ft. high, rough or hairy, branched. Leaves: Alternate, narrowly oblong or lanceolate, saw-edged, 3 to 10 in. long, rough. Preferred Habitat - Moist soil, meadows, fields. Flowering Season - July-September. Distribution - Massachusetts to Georgia, and westward to the Mississippi.
Emerson says a weed is a plant whose virtues we have not yet discovered; but surely it is no small virtue in the iron-weed to brighten the rides and low meadows throughout the summer with bright clusters of bloom. When it is on the wane, the asters, for which it is sometimes mistaken, begin to appear, but an instant's comparison shows the difference between the two flowers. After noting the yellow disk in the center of an aster, it is not likely the iron-weed's thistle-like head of ray florets only will ever again be confused with it. Another rank-growing neighbor with which it has been confounded by the novice is the Joe Pye weed, a far paler, pinkish flower.
To each tiny floret, secreting nectar in its tube, many insects, attracted by the bright color of the iron-weed standing high above surrounding vegetation, come to feast. Long-lipped bees and flies rest awhile for refreshment, but butterflies of many beautiful kinds are by far the most abundant visitors. Pollen carried out by the long, hairy styles as they extend to maturity must attach itself to their tongues. The tiger swallow-tail butterfly appears to have a special preference for this flower. (See Self-Heal.)
COMMON or SCALY BLAZING STAR; COLIC-ROOT; RATTLESNAKE MASTER; BUTTON SNAKEROOT (Lacinaria squarrosa; Liatris squarrosa of Gray) Thistle family
Flower-heads - Composite, about 1 in. long, bright purple or rose purple, of tubular florets only, from an involucre of overlapping, rigid, pointed bracts; each of the few flower-heads from the leaf axils along a slender stem in a wand-like raceme. Stem: 1/2 to 2 ft. high. Leaves: Alternate, narrow, entire. Preferred habitat - Dry, rich soil. Flowering Season - June-September. Distribution - Ontario to the Gulf of Mexico, westward to Nebraska.
Beginning at the top, the apparently fringed flower-heads open downward along the wand, whose length depends upon the richness of the soil. All of the flowers are perfect and attract long-tongued bees and flies (especially Exoprosopa fasciata) and butterflies, which, as they sip from the corolla tube, receive the pollen carried out and exposed on the long divisions of the style. Some people have pretended to cure rattlesnake bites with applications of the globular tuber of this and the next species.
The LARGE BUTTON SNAKEROOT, BLUE BLAZING STAR, or GAY FEATHER (L. scariosa), may attain six feet, but usually not more than half that height; and its round flower-heads normally stand well away from the stout stem on foot-stems of their own. The bristling scales of the involucre, often tinged with purple at the tips, are a conspicuous feature. With much the same range and choice of habitat as the last species, this Blazing Star is a later bloomer, coming into flower in August, and helping the goldenrods and asters brighten the landscape throughout the early autumn. The name of gay feather, miscellaneously applied to several blazing stars, is especially deserved by this showy beauty of the family.
Unlike others of its class, the DENSE BUTTON SNAKEROOT, DEVIL'S BIT, ROUGH or BACKACHE ROOT, PRAIRIE PINE or THROATWORT (L. spicata), the commonest species we have, chooses moist soil, even salt marshes near the coast, and low meadows throughout a range nearly corresponding with that of the scaly blazing star. Resembling its relatives in general manner of growth, we note that its oblong involucre, rounded at the base, has blunt, not sharply pointed, bracts; that the flower-heads are densely set close to the wand for from four to fifteen inches; that the five to thirteen bright rose-purple florets which compose each head occasionally come white; that its leaves are long and very narrow, and that October is not too late to find the plant in bloom.
BLUE and PURPLE ASTERS or STARWORTS Thistle family
Evolution teaches us that thistles, daisies, sunflowers, asters, and all the triumphant horde of composites were once very different flowers from what we see today. Through ages of natural selection of the fittest among their ancestral types, having finally arrived at the most successful adaptation of their various parts to their surroundings in the whole floral kingdom, they are now overrunning the earth. Doubtless the aster's remote ancestors were simple green leaves around the vital organs, and depended upon the wind, as the grasses do - a most extravagant method - to transfer their pollen. Then some rudimentary flower changed its outer row of stamens into petals, which gradually took on color to attract insects and insure a more economical method of transfer. Gardeners today take advantage of a blossom's natural tendency to change stamens into petals when they wish to produce double flowers. As flowers and insects developed side by side, and there came to be a better and better understanding between them of each other's requirements, mutual adaptation followed. The flower that offered the best advertisement, as the composites do, by its showy rays; that secreted nectar in tubular flowers where no useless insect could pilfer it; that fastened its stamens to the inside wall of the tube where they must dust with pollen the underside of every insect, unwittingly cross-fertilizing the blossom as he crawled over it; that massed a great number of these tubular florets together where insects might readily discover them and feast with the least possible loss of time - this flower became the winner in life's race. Small wonder that our June fields are white with daisies and the autumn landscape is glorified with goldenrod and asters!
Since North America boasts the greater part of the two hundred and fifty asters named by scientists, and as variations in many of our common species frequently occur, the tyro need expect no easy task in identifying every one he meets afield. However, the following are possible acquaintances to everyone:
In dry, shady places the LARGE or BRLEAVED ASTER (A. macrophyllus), so called from its three or four conspicuous, heart-shaped leaves on long petioles, in a clump next the ground, may be more easily identified by these than by the pale lavender or violet flower-heads of about sixteen rays each which crown its reddish angular stem in August and September. The disk turns reddish brown.
In prairie soil, especially about the edges of woods in western New York, southward and westward to Texas and Minnesota, the beautiful SKY-BLUE ASTER (A. azureus) blooms from August till after frost. Its slender, stiff, rough stem branches above to display the numerous bright blue flowers, whose ten to twenty rays measure only about a quarter of an inch in length. The upper leaves are reduced to small flat bracts; the next are linear; and the lower ones, which approach a heart shape, are rough on both sides, and may be five or six inches long.
Much more branched and bushy is the COMMON BLUE, BRANCHING, WOOD, or HEART-LEAVED ASTER (A. cordifolius), whose generous masses of small, pale lavender flower-heads look like a mist hanging from one to five feet above the earth in and about the woods and shady rides from September even to December in favored places.
The WAVY or VARIOUS-LEAVED ASTER or SMALL FLEABANE (A. undulatus) has a stiff, rough, hairy, widely branching stalk, whose thick, rough lowest leaves are heart-shaped and set on long foot-stems; above these, the leaves have shorter stems, dilating where they clasp the stalk; the upper leaves, lacking stems, are seated on it, while those of the branches are shaped like tiny awls. The flowers, which measure less than an inch across, often grow along one side of an axis as well as in the usual raceme. Eight to fifteen pale blue to violet rays surround the disks which, yellow at first, become reddish brown in maturity. We find the plant in dry soil, blooming in September and October.
By no means tardy, the LATE PURPLE ASTER, so-called, or PURPLE DAISY (A. patens), begins to display its purplish-blue, daisy-like flower-heads early in August, and farther north may be found in dry, exposed places only until October. Rarely the solitary flowers, that are an inch across or more, are a deep, rich violet. The twenty to thirty rays which surround the disk, curling inward to dry, expose the vase-shaped, green, shingled cups that terminate each little branch. The thick, somewhat rigid, oblong leaves, tapering at the tip, brn at the base to clasp the rough, slender stalk. Range similar to the next species.
Certainly from Massachusetts, northern New York, and Minnesota southward to the Gulf of Mexico one may expect to find the NEW ENGLAND ASTER or STARWORT (A. Novae-Angliae) one of the most striking and widely distributed of the tribe, in spite of its local name. It is not unknown in Canada. The branching clusters of violet or magenta-purple flower-heads, from one to two inches across - composites containing as many as forty to fifty purple ray florets around a multitude of perfect five-lobed, tubular, yellow disk florets in a sticky cup - shine out with royal splendor above the swamps, moist fields, and rides from August to October. The stout, bristle-hairy stem bears a quantity of alternate lance-shaped leaves lobed at the base where they clasp it.
In even wetter ground we find the RED-STALKED, PURPLE-STEMMED, or EARLY PURPLE ASTER, COCASH, SWANWEED, or MEADOW SCABISH (A. puniceus) blooming as early as July or as late as November. Its stout, rigid stem, bristling with rigid hairs, may reach a height of eight feet to display the branching clusters of pale violet or lavender flowers. The long, blade-like leaves, usually very rough above and hairy along the midrib beneath, are seated on the stem. The lovely SMOOTH or BLUE ASTER (A. laevis), whose sky-blue or violet flower-heads, about one inch br are common through September and October in dry soil and open woods, has strongly clasping, oblong, tapering leaves, rough margined, but rarely with a saw-tooth, toward the top of the stem, while those low down on it gradually narrow into clasping wings.
In dry, sandy soil, mostly near the coast, from Massachusetts to Delaware, grows one of the loveliest of all this beautiful clan, the LOW, SHOWY, or SEASIDE PURPLE ASTER (A. spectabilis). The stiff, usually unbranched stem does its best in attaining a height of two feet. Above, the leaves are blade-like or narrowly oblong, seated on the stem, whereas the tapering, oval basal leaves are furnished with long footstems, as is customary with most asters. The handsome, bright, violet-purple flower-heads, measuring about an inch and a half across, have from fifteen to thirty rays, or only about half as many as the familiar New England aster. Season August to November.
The low-growing BOG ASTER (A. nemoralis), not to be confused with the much taller Red-stalked species often found growing in the same swamp, and having, like it, flower-heads measuring about an inch and a half across, has rays that vary from light violet purple to rose pink. Its oblong to lance-shaped leaves, only two inches long at best, taper to a point at both ends, and are seated on the stem. We look for this aster in sandy bogs from New Jersey northward and westward during August and September.
The STIFF or SAVORY-LEAVED ASTER, SANDPAPER, or PINE STARWORT (Ionactis linariifolius), now separated from the other asters into a genus by itself, is a low, branching little plant with no basal leaves, but some that are very narrow and blade-like, rigid, entire and one-nerved, ascending the stiff stems. The leaves along the branches are minute and awl-shaped, like those on a branch of pine. Only from ten to fifteen violet ray flowers (pistillate) surround the perfect disk florets. From Quebec to the Gulf of Mexico, and westward beyond the Mississippi this prim little shrub grows in tufts on dry or rocky soil, and blooms from July to October.
ROBIN'S, or POOR ROBIN'S, or ROBERT'S PLANTAIN; BLUE SPRING DAISY; DAISY-LEAVED FLEABANE (Erigeron pulchellus; E. bellifolium of Gray) Thistle family
Flower-heads - Composite, daisy-like, 1 to 1/2 in. across; the outer circle of about 50 pale bluish-violet ray florets; the disk florets greenish yellow. Stem: Simple, erect, hairy, juicy, flexible, from 10 in. to 2 ft. high, producing runners and offsets from base. Leaves: Spatulate, in a flat tuft about the root; stem leaves narrow, more acute, seated, or partly clasping. Preferred Habitat - Moist ground, hills, banks, grassy fields. Flowering Season - April-June. Distribution - United States and Canada, east of the Mississippi.
Like an aster blooming long before its season, Robin's plantain wears a finely cut lavender fringe around a yellow disk of minute florets; but one of the first, not the last, in the long procession of composites has appeared when we see gay companies of these flowers nodding their heads above the grass in the spring breezes as if they were village gossips.
Doubtless it was the necessity for attracting insects which led the Robin's plantain and other composites to group a quantity of minute florets, each one of which was once an independent, detached blossom, into a common head. In union there is strength. Each floret still contains, however, its own tiny drop of nectar, its own stamens, its own pistil connected with embryonic seed below; therefore, when an insect alights where he can get the greatest amount of nectar for the least effort, and turns round and round to exhaust each nectary, he is sure to dust the pistils with pollen, and so fertilize an entire flower-head in a trice. The lavender fringe and the hairy involucre and stem serve the end of discouraging crawling insects, which cannot transfer pollen from plant to plant, from pilfering sweets that cannot be properly paid for. Small wonder that, although the composites have attained to their socialistic practices at a comparatively recent day as evolutionists count time, they have become as individuals and as species the most numerous in the world; the thistle family, dominant everywhere, containing not less than ten thousand members.
COMMON or PHILADELPHIA FLEABANE, or SKEVISH (E. Philadelphicus), a smaller edition of Robin's plantain, with a more findely cut fringe, its reddish-purple ray florets often numbering one hundred and fifty, may be found in low fields and woods throughout North America, except in the circumpolar regions.
THISTLES (Carduus) Thistle family
Is land fulfilling the primal curse because it brings forth thistles? So thinks the farmer, no doubt, but not the goldfinches which daintily feed among the fluffy seeds, nor the bees, nor the "painted lady," which may be seen in all parts of the world where thistles grow, hovering about the beautiful rose-purple flowers. In the prickly cradle of leaves, the caterpillar of this thistle butterfly weaves a web around its main food store.
When the Danes invaded Scotland, they stole a silent night march upon the Scottish camp by marching barefoot; but a Dane inadvertently stepped on a thistle, and his sudden, sharp cry, arousing the sleeping Scots, saved them and their country: hence the Scotch emblem.
From July to November blooms the COMMON, BURR, SPEAR, PLUME, BANK, HORSE, BULL, BLUE, BUTTON, BELL, or RIDE THISTLE (C. lanceolatus or Circium lanceolatum of Gray), a native of Europe and Asia, now a most thoroughly naturalized American from Newfoundland to Georgia, westward to Nebraska. Its violet flower-heads, about an inch and a half across, and as high as wide, are mostly solitary at the ends of formidable branches, up which few crawling creatures venture. But in the deep tube of each floret there is nectar secreted for the flying visitor who can properly transfer pollen from flower to flower. Such a one suffers no inconvenience from the prickles, but, on the contrary, finds a larger feast saved for him because of them. Dense, matted, wool-like hairs, that cover the bristling stems of most thistles, make climbing mighty unpleasant for ants, which ever delight in pilfering sweets. Perhaps one has the temerity to start upward.
"Fain would I climb, yet fear to fall." "If thy heart fail thee, climb not at all,"
might be the ant's passionate outburst to the thistle, and the thistle's reply, instead of a Sir Walter and Queen Elizabeth couplet. Long, lance-shaped, deeply cleft, sharply pointed, and prickly dark green leaves make the ascent almost unendurable; nevertheless the ant bravely mounts to where the bristle-pointed, overlapping scales of the deep green cup hold the luscious flowers. Now his feet becoming entangled in the cottony fibers wound about the scaly armor, and a bristling bodyguard thrusting spears at him in his struggles to escape, death happily releases him. All this tragedy to insure the thistle's cross-fertilized seed that, seated on the autumn winds, shall be blown far and wide in quest of happy conditions for the offspring!
Sometimes the PASTURE or FRAGRANT THISTLE (C. odoratus or C. pumilum of Gray) still further protects its beautiful, odorous purple or whitish flower-head, that often measures three inches across, with a formidable array of prickly small leaves just below it. In case a would-be pilferer breaks through these lines, however, there is a slight glutinous strip on the outside of the bracts that compose the cup wherein the nectar-filled florets are packed; and here, in sight of Mecca, he meets his death, just as a bird is caught on limed twigs. The pasture thistle, whose range is only from Maine to Delaware, blooms from July to September.
Even gentle Professor Gray hurls anathema at the CANADA THISTLE; "a vile pest" he calls it. As CURSED, CORN, HARD, and CREEPING THISTLE it is variously known here and in Europe, whence it came to overrun our land from Newfoundland to Virginia, westward to Nebraska. By horizontal rootstocks it creeps and forms patches almost impossible to eradicate. The small reddish-purple flower-heads, barely an inch across, usually contain about a hundred florets each. In their tubes the abundant nectar rises high, so that numerous insects, even with the shortest tongues, are able to enjoy it. Not only bees and butterflies, but wasps, flies, and beetles feast diligently. When a floret opens, a quantity of pollen emerges at the upper end of the anther cylinder, pressed up by the growing style. Owing to their slight stickiness and the sharp processes over their entire surface, the pollen grains, which readily cling to the hairs of insects, are transported to the two-branched, hairy stigma of an older floret. But even should insects not visit the flower (and in fine weather they swarm about it), it is marvelously adapted to fertilize itself. Farmers may well despair of exterminating a plant so perfectly equipped in every part; to win life's battles.
"The colour of purple...was, amongst the ancients, typical of royalty. It was a kind of red richly shot with blue, and the dye producing it was attained from a shell found in considerable numbers off the coast of Tyre, and on the shore near the site of that ancient city, great heaps of such shells are still to be found. The production of the true royal purple dye was a very costly affair, and therefore it was often imitated with a mixture of cochineal and indigo..." - J. JAMES TISSOT.
As many so-called purple flowers are more strictly magenta, the reader is referred to the next group if he has not found the flower for which he is in search here. Also to the "White and Greenish" section since many colored flowers show a tendency to revert to the white type from which, doubtless, all were evolved. He should remember that all flowers are more or less variable in shade, according to varying conditions.
