Distribution - From the Carolinas and Wisconsin far northward.

To name ca.n.a.ls, bridges, city thoroughfares, booming factory towns after DeWitt Clinton seems to many appropriate enough; but why a shy little woodland flower? As fitly might a wee white violet carry down the name of Theodore Roosevelt to posterity!

"Gray should not have named the flower from the Governor of New York," complains Th.o.r.eau. "What is he to the lovers of flowers in Ma.s.sachusetts? If named after a man, it must be a man of flowers." So completely has Clinton, the practical man of affairs, obliterated Clinton, the naturalist, from the popular mind, that, were it not for this plant keeping his memory green, we should be in danger of forgetting the weary, overworked governor, fleeing from care to the woods and fields; pursuing in the open air the study which above all others delighted and refreshed him; revealing in every leisure moment a too-often forgotten side of his many-sided greatness.

INDIAN CUc.u.mBER-ROOT (Medeola Virginiana) Lily-of-the-valley family

Flowers - Greenish yellow, on fine, curving footstalks, in a loose cl.u.s.ter above a circle of leaves. Perianth of 6 wide-spread divisions about 1/4 in. long; 6 reddish-brown stamens; 3 long reddish-brown styles, stigmatic on inner side. Stem: 1 to 2 1/2 ft. high, unbranched, cottony when young. Leaves: Of flowering plants, in 2 whorls; lower whorl of 5 to 9 large, thin, oblong, taper-pointed leaves above the middle of stem; upper whorl of 3 to 5 small, oval, pointed leaves 1 to 2 in. long, immediately under flowers. Flowerless plants with a whorl at summit. Fruit: Round, dark-purple berries.



Preferred Habitat - Moist woods and thickets.

Flowering Season - May-June.

Distribution - Nova Scotia and Minnesota, southward nearly to the Gulf of Mexico.

Again we see the leaves of a plant coming to the aid of otherwise inconspicuous flowers to render them more attractive. By placing themselves in a circle just below these little spidery blossoms of weak and uncertain coloring, some of the Indian cuc.u.mber's leaves certainly make them at least noticeable, if not showy. It would be short-sighted philanthropy on the leaves' part to help the flowers win insect wooers at the expense of the plant's general health; therefore those in the upper whorl are fewer and much smaller than the leaves in the lower circle, and a sufficient length of stem separates them to allow the sunlight and rain to conjure with the chlorophyll in the group below.

While there is a chance of nectar being pilfered from the flowers by ants, the stem is cottony and ensnares their feet. In September, when small cl.u.s.ters of dark-purple berries replace the flowers, and rich tints dye the leaves, the plant is truly beautiful - of course to invite migrating birds to disperse its seeds. It is said the Indians used to eat the horizontal, white, fleshy rootstock, which has a flavor like a cuc.u.mber's.

CARRION-FLOWER (Smilax herbacea) Smilax family

Flowers - Carrion-scented, yellowish-green, 15 to 80 small, 6-parted ones cl.u.s.tered in an umbel on a long peduncle. Stem: Smooth, unarmed, climbing with the help of tendril-like appendages from the base of leafstalks. Leaves: Egg-shaped, heart-shaped, or rounded, pointed tipped, parallel-nerved, petioled. Fruit: Bluish-black berries.

Preferred Habitat - Moist soil, thickets, woods, roadside fences.

Flowering Season - April-June.

Distribution - Northern Canada to the Gulf States, westward to Nebraska.

"It would be safe to say," says John Burroughs, "that there is a species of smilax with an unsavory name, that the bee does not visit, herbacea. The production of this plant is a curious freak of nature.... It would be a cruel joke to offer it to any person not acquainted with it, to smell. It is like the vent of a charnel-house." (Th.o.r.eau compared its odor to that of a dead rat in a wall!) "It is first cousin to the trilliums, among the prettiest of our native wild flowers," continues Burroughs, "and the same bad blood crops out in the purple trillium or birthroot."

Strange that so close an observer as Burroughs or Th.o.r.eau should not have credited the carrion-flower with being something more intelligent than a mere repellent freak! Like the purple trillium (q.v.), it has deliberately adapted itself to please its benefactors, the little green flesh flies so commonly seen about untidy butcher shops in summer. These, sharing with many beetles the unthankful task of removing putrid flesh and fowl from the earth, acting the part of scavengers for nature, are naturally attracted to carrion-scented flowers. Of these they have an ungrudged monopoly. But the purple trillium has an additional advantage in both smelling and looking like the same thing - a piece of raw meat past its prime. Bees and b.u.t.terflies, with their highly developed aesthetic sense, ever delighting in beautiful colors, perfume, and nectar, naturally let such flowers as these alone - another object aimed at by them, for then the flies get all the pollen they can eat. Some they transfer, of course, from the larger staminate flowers to the smaller pistillate ones as they crawl over one umbel of the carrion-flower, then alight on another.

Presently fruit begins to set, and we can approach the luxuriant vine without offence to our noses. The beautiful glossy green foliage takes on resplendent tints in early autumn - again with interested motives, for are there not seeds within the little bluish-black berries, waiting for the birds to distribute them during their migration?

The vicious CATBRIER, GREENBRIER, or HORSEBRIER (S.

rotundifolia), similar to the preceding, except that its four-angled stem is well armed with green p.r.i.c.kles, its beautiful glossy, decorative leaves are more rounded, and its greenish flower umbels lack foul odor, scarcely needs description. Who has not encountered it in the roadside and woodland thickets, where it defiantly bars the way?

In the most inaccessible part of such a briery tangle, that rollicking polyglot, the yellow-breasted chat, loves to hide its nest. Indeed, many birds can say with Br'er Rabbit that they were "bred en bawn in a brier-patch." Throughout the eastern half of the United $tates and Upper Canada the catbrier displays its insignificant little blossoms from April to June for a miscellaneous lot of flies - insects which are content with the slightest floral attractions offered. The florist's staple vine popularly known as "SMILAX" (Myrslphyllum asparagoides), a native of the Cape of Good Hope, is not even remotely connected with true Smilaceae.

YELLOW STAR-GRa.s.s (Hypoxis hirsuta; H. erecta of Gray) Amaryllis family

Flowers - Bright yellow within, greenish and hairy outside, about 1/2 in. across, 6-parted; the perianth divisions spreading, narrowly oblong; a few flowers at the summit of a rough, hairy scape 2 to 6 in. high. Leaves: All from an egg-shaped corm; mostly longer than scapes, slender, gra.s.s-like, more or less hairy.

Preferred Habitat - Dry, open woods, prairies, gra.s.sy waste places, fields.

Flowering Season - May-October.

Distribution - From Maine far westward, and south to the Gulf of Mexico.

Usually only one of these little blossoms in a cl.u.s.ter on each plant opens at a time; but that one peers upward so brightly from among the gra.s.s it cannot well be overlooked. Sitting in a meadow sprinkled over with these yellow stars, we see coming to them many small bees - chiefly Halictus - to gather pollen for their unhatched babies' bread. Of course they do not carry all the pollen to their tunneled nurseries; some must often be rubbed off on the sticky pistil tip in the center of other stars. The stamens radiate, that self-fertilization need not take place except as a last extremity. Visitors failing, the little flower closes, bringing its pollen-laden anthers in contact with its own stigma.

BLACKBERRY LILY (Gemmingia Ciminensis; Pardanthus Chinensis of Gray) Iris family

Flowers - Deep orange color, speckled irregularly with crimson and purple within (Pardos = leopard; anthos = flower); borne in terminal, forked cl.u.s.ters. Perianth of 6 oblong, petal-like, spreading divisions; 6 stamens with linear anthers; style thickest above, with 3 branches. Stem: 1 1/2 to 4 ft. tall, leafy. Leaves: Like the iris; erect, folded blades, 8 to 10 in.

long. Fruit: Resembling a blackberry; an erect ma.s.s of round, black, fleshy seeds, at first concealed in a fig-shaped capsule, whose 3 valves curve backward, and finally drop off.

Preferred habitat - Roadsides and hills.

Flowering Season - June-July.

Distribution - Connecticut to Georgia, westward to Indiana and Missouri.

How many beautiful foreign flowers, commonly grown in our gardens here, might soon become naturalized Americans were we only generous enough to lift a few plants, scatter a few seeds over our fences into the fields and roadsides - to raise the bars of their prison, as it were, and let them free! Many have run away, to be sure. Once across the wide Atlantic, or wider Pacific, their pa.s.sage paid (not sneaking in among the ballast like the more fortunate weeds), some are doomed to stay in prim, rigidly cultivated flower beds forever; others, only until a chance to bolt for freedom presents itself, and away they go. Lucky are they if every flower they produce is not picked before a single seed can be set.

This blackberry lily of gorgeous hue originally came from China.

Escaping from gardens here and there, it was first reported as a wild flower at East Rock, Connecticut; other groups of vagabonds were met marching along the roadsides on Long Island; near Suffern, New York; then farther southward and westward, until it has already attained a very respectable range. Every plant has some good device for sending its offspring away from home to found new colonies, if man would but let it alone. Better still, give the eager travelers a lift!

LARGE YELLOW LADY'S SLIPPER; WHIPPOORWILL'S SHOE; YELLOW MOCCASIN FLOWER (Cypripedium hirsutum; C. p.u.b.escens of Gray) Orchid family

Flower - Solitary, large, showy, borne at the top of a leafy stem to 2 ft. high. Sepals 3, 2 of them united, greenish or yellowish, striped with purple or dull red, very long, narrow; 2 petals, brown, narrower, twisting; the third an inflated sac, open at the top, 1 to 2 in. long, pale yellow, purple lined white hairs within; sterile stamen triangular; stigma thick. Leaves: Oval or elliptic, pointed, 3 to 5 in, long, parallel-nerved, sheathing.

Preferred Habitat - Moist or boggy woods and thickets; hilly ground.

Flowering Season - May-July.

Distribution - Nova Scotia to Alabama, westward to Minnesota and Nebraska.

Swinging outward from a leaf-clasped stem, this orchid attracts us by its flaunted beauty and decorative form from tip to root, not less than the aesthetic little bees for which its adornment and mechanism are so marvelously adapted. Doubtless the heavy, oily odor is an additional attraction to them. Parallel purplish lines, converging toward the circular opening of the pale yellow, inflated pouch, guide the visitor into a s.p.a.cious banquet-hall (labellum) such as the pink lady's slipper (q.v.) also entertains her guests in. Fine hairs within secrete tiny drops of fluid at their tips - a secretion which hardens into a brittle crust, like a syrup's, when it dries. Darwin became especially interested in this flower through a delightful correspondence with Professor Asa Gray, who was the first to understand it, and he finally secured a specimen to experiment on.

"I first introduced some flies into the labellum through the large upper opening," Darwin wrote, "but they were either too large or too stupid, and did not crawl out properly. I then caught and placed within the labellum a very small bee which seemed of about the right size, namely Andrena parvula.... The bee vainly endeavored to crawl out again the same way it entered, but always fell backwards, owing to the margins being inflected.

The labellum thus acts like one of those conical traps with the edges turned inwards, which are sold to catch beetles and c.o.c.kroaches in London kitchens. It could not creep out through the slit between the folded edges of the basal part of the labellum, as the elongated, triangular, rudimentary stamen here closes the pa.s.sage. Ultimately it forced its way out through one of the small orifices close to one of the anthers, and was found when caught to be smeared with the glutinous pollen. I then put the same bee into another labellum; and again it crawled out through one of the small orifices, always covered with pollen. I repeated the operation five times, always with the same result. I afterwards cut away the labellum, so as to examine the stigma, and found its whole surface covered with pollen. It should be noticed that an insect in making its escape, must first brush past the stigma and afterwards one of the anthers, so that it cannot leave pollen on the stigma, until being already smeared with pollen from one flower it enters another; and thus there will be a good chance of cross-fertilization between two distinct plants.... Thus the use of all parts of the flower, - namely, the inflected edges, or the polished inner sides of the labellum; the two orifices and their position close to the anthers and stigma, - the large size of the medial rudimentary stamen, - are rendered intelligible. An insect which enters the labellum is thus compelled to crawl out by one of the two narrow pa.s.sages, on the sides of which the pollen-ma.s.ses and stigma are placed."

These common orchids, which are not at all difficult to naturalize in a well-drained, shady spot in the garden, should be lifted with a good ball of earth and plenty of leaf-mould immediately after flowering. Here we can note little American Andrena bees unwittingly becoming the flower's slaves. Several species of exotic cypripediums are so common in the city florist's shops every one has an opportunity to study their marvelous structure.

The similar SMALL YELLOW LADY'S SLIPPER (C. parviflorum), a delicately fragrant orchid about half the size of its big sister, has a brighter yellow pouch, and occasionally its sepals and petals are purplish. As they usually grow in the same localities, and have the same blooming season, opportunities for comparison are not lacking. This fairer, sweeter, little orchid roams westward as far as the State of Was.h.i.+ngton.

YELLOW FRINGED ORCHIS (Habenaria ciliaris) Orchid family

Flowers - Bright yellow or orange, borne in a showy, closely set, oblong spike, 3 to 6 in. long. The lip of each flower copiously fringed; the slender spur 1 to 1 1/2 in. long; similar to white fringed orchis (q.v.); and between the two, intermediate pale yellow hybrids may be found. Stem: Slender, leafy, 1 to 2 1/2 feet high. Leaves: Lance-shaped, clasping.

Preferred Habitat - Moist meadows and sandy bogs.

Flowering Season - July-August.

Distribution - Vermont to Florida; Ontario to Texas.

Where this brilliant, beautiful orchid and its lovely white sister grow together in the bog - which cannot be through a very wide range, since one is common northward, where the other is rare, and vice versa - the yellow fringed orchis will be found blooming a few days later. In general structure the plants closely resemble each other. Their similar method of enforcing payment for a sip of nectar concealed in a tube so narrow and deep none but a sphinx moth or b.u.t.terfly may drain it all (though large b.u.mblebees occasionally get some too, from br.i.m.m.i.n.g nectaries) has been described (q.v.), to which the interested reader is referred. Both these orchids have their sticky discs projecting unusually far, as if raised on a pedicel - an arrangement which indicates that they "are to be stuck to the face or head of some nectar-sucking insect of appropriate size that visits the flowers," wrote Dr. Asa Gray over forty years ago. Various species of hawk moths, common in different parts of our area, of course have tongues of various lengths, and naturally every visitor does not receive his load of pollen on the same identical spot. At dusk, when sphinx moths begin their rounds, it will be noticed that the white and yellow flowers remain conspicuous long after blossoms of other colors have melted into the general darkness. Such flowers as cater to these moths, if they have fragrance, emit it then most strongly, as an additional attraction. Again, it will be noticed that few such flowers provide a strong projecting petal-platform for visitors to alight on; that would be superfluous, since sphinx moths suck while hovering over a tube, with their wings in exceedingly rapid motion, just like a hummingbird, for which the larger species are so often mistaken at twilight. This deep-hued orchid apparently attracts as many b.u.t.terflies as sphinx moths, which show a predilection for the white species.

>From Ontario and the Mississippi eastward, and southward to the Gulf, the TUBERCLED or SMALL PALE GREEN ORCHIS (H. flava) lifts a spire of inconspicuous greenish-yellow flowers, more attractive to the eye of the structural botanist than to the aesthete. It blooms in moist places, as most orchids do, since water with which to manufacture nectar enough to fill their deep spurs is a prime necessity. Orchids have arrived at that pinnacle of achievement that it is impossible for them to fertilize themselves. More than that, some are absolutely sterile to their own pollen when it is applied to their stigmas artificially with insect aid, however, a single plant has produced over 1,000,700 seeds. No wonder, then, that, as a family, they have adopted the most marvelous blandishments and mechanism in the whole floral kingdom to secure the visits of that special insect to which each is adapted, and, having secured him, to compel him unwittingly to do their bidding. In the steaming tropical jungles, where vegetation is luxuriant to the point of suffocation, and where insect life swarms in mvriads undreamed of here, we can see the best of reasons for orchids mounting into trees and living on air to escape strangulation on the ground, and for donning larger and more gorgeous apparel to attract attention in the fierce compet.i.tion for insect trade waged about them. Here, where the struggle for survival is incomparably easier, we have terrestrial orchids, small, and quietly clad, for the most part.

Having the gorgeous, exotic air plants of the hothouse in mind, this little tubercled orchis seems a very poor relation indeed.

In June and July, about a week before the ragged orchis comes out, we may look for this small, fringeless sister. Its clasping leaves, which decrease in size as they ascend the stem (not to shut off the light and rain from the lower ones), are parallel-veined, elliptic, or, the higher ones, lance-shaped. A prominent tubercle, or palate, growing upward from the lip, almost conceals the entrance to the nectary. and makes a side approach necessary. Why? Usually an insect has free, straight access down the center of a flower's throat, but here he cannot have it. A slender tongue must be directed obliquely from above into the spur, and it will enter the discal groove as a thread enters the eye of a needle. By this arrangement the tongue must certainly come in contact with one of the sticky discs to which an elongated pollen gland is attached. The cement on the disc hardening even while the visitor sucks, the pollen gland is therefore drawn out, because firmly attached to his tongue. At first the pollen ma.s.s stands erect on the proboscis; but in the fraction of a moment which it takes a b.u.t.terfly to flit to another blossom, it has bent forward automatically into the exact position required for it to come in contact with the sticky stigma of the next tubercled orchis entered, where it will be broken off. Now we understand the use of the palate. b.u.t.terfly collectors often take specimens with remnants of these pollen stumps stuck to their tongues. In his cla.s.sical work "On the Fertilization of Orchids by Insects," Darwin tells of finding a mottled rustic b.u.t.terfly whose proboscis was decorated with eleven pairs of pollen ma.s.ses, taken from as many blossoms of the pyramidal orchis. Have these flowers no mercy on their long-suffering friends? A bee with some orchid pollen-stumps attached to its head was once sent to Mr. Frank Ches.h.i.+re, the English expert who had just discovered some strange bee diseases.

He was requested to name the malady that had caused so abnormal an outgrowth on the bee's forehead!

Often found growing in the same bog with the tubercled species is the RAGGED or FRINGED GREEN ORCHIS (H. lacera), so inconspicuous we often overlook it unawares. Examine one of the dingy, greenish-yellow flowers that are set along the stern in a spike to make all the show in the world possible, each with its three-parted, spreading lip finely and irregularly cut into thread-like fringe to hail the pa.s.sing b.u.t.terfly, and we shall see that it, too, has made ingenious provision against the draining of its spur by a visitor without proper pay for his entertainment. Even without the gay color that b.u.t.terflies ever delight in, these flowers contain so much nectar in their spurs, neither b.u.t.terflies nor large b.u.mblebees are long in hunting them out. In swamps and wet woodland from Nova Scotia to Georgia, and westward to the Mississippi, the ragged orchis blooms in June or July.

LARGE YELLOW POND or WATER LILY; COW LILY; SPATTER-DOCK (Nymphaea advena; Nupisar advena of Gray) Water-lily family

Flowers - Yellow or greenish outside, rarely purple tinged, round, depressed, 1 1/2 to 3 1/2 in. across. Sepals 6, unequal, concave, thick, fleshy; petals stamen-like, oblong, fleshy, short; stamens very numerous, in 5 to 7 rows; pistil compounded of many carpels, its stigmatic disc pale red or yellow, with 12 to 24 rays. Leaves: Floating, or some immersed, large, thick, sometimes a foot long, egg-shaped or oval, with a deep cleft at base, the lobes rounded.

Preferred Habitat - Standing water, ponds, slow streams.

Flowering Season - April-September.

Distribution - Rocky Mountains eastward, south to the Gulf of Mexico, north to Nova Scotia.
