(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 butterfly may drain it all (though large bumblebees occasionally get some too, from brimming 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 butterflies 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 competition 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 mass stands erect on the proboscis; but in the fraction of a moment which it takes a butterfly 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. Butterfly collectors often take specimens with remnants of these pollen stumps stuck to their tongues. In his classical work "On the Fertilization of Orchids by Insects," Darwin tells of finding a mottled rustic butterfly whose proboscis was decorated with eleven pairs of pollen masses, 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 Cheshire, 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 passing butterfly, 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 butterflies ever delight in, these flowers contain so much nectar in their spurs, neither butterflies nor large bumblebees 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. Comparisons were ever odious. Because the yellow water lily has the misfortune to claim relationship with the sweet-scented white species (q.v.), must it never receive its just meed of praise? Hiawatha's canoe, let it be remembered, "Floated on the river Like a yellow leaf in autumn, Like a yellow water-lily." But even those who admire Longfellow's lines see no beauty in the golden flower-bowls floating among the large, lustrous, leathery leaves. By assuming the functions of petals, the colored sepals advertise for insects. Beetles, which answer the first summons to a free lunch, crowd in as the sepals begin to spread. In the center the star-like disc, already sticky, is revealed, and on it any pollen they have carried with them from older flowers necessarily rubs off. At first, or while the stigma is freshly receptive to pollen, an insect cannot make his entrance except by crawling over this large, sticky plate. At this time, the anthers being closed, self-fertilization is impossible. A day or two later, after the pollen begins to ripen on countless anthers, the flower is so widely open that visitors have no cause to alight in the center; anyway, no harm could result if they did, cross-fertilization having been presumably accomplished. While beetles (especially Donacia) are ever abundant visitors, it is likely they do much more harm than good. So eagerly do they gnaw both petals and stamens, which look like loops of narrow yellow ribbon within the bowl of an older flower, that, although they must carry some pollen to younger flowers as they travel on, it is probable they destroy ten times more than their share. Flies transport pollen too. The smaller bees (Halictus and Andrena chiefly) find some nectar secreted on the outer faces of the stamen-like petals, which they mix with pollen to make their babies' bread. The very beautiful native AMERICAN LOTUS (Nelumbo lutea), also known as WATER CHINKAPIN or WANKAPIN, found locally in Ontario, the Connecticut River, some lakes, slow streams, and ponds in New Jersey, southward to Florida, and westward to Michigan and Illinois, Indian Territory and Louisiana, displays its pale yellow flowers in July and August. They measure from four to ten inches across, and suggest a yellow form of the sweet-scented white water lily; but there are fewer petals, gradually passing into an indefinite number of stamens. The great round, ribbed leaves, smooth above, hairy beneath, may be raised high above the water, immersed or floating. Both leaf and flower stalks contain several large air canals. The flowers which are female when they expand far enough for a pollen-laden guest to crawl into the center, are afterward male, securing cross-fertilization by this means, just as the yellow pond lily does; only the small bees must content themselves here with pollen only - a diet that pleases the destructive beetles and the flies (Syrphidae) perfectly. Japanese artists especially have taught us how much of the beauty of a Nelumbo we should lose if it ripened its decorative seed-vessel below the surface as the sweet-scented white water lily does. This flat-topped receptacle, held erect, has its little round nuts imbedded in pits in its surface, ready to be picked out by aquatic birds, and distributed by them in their wanderings. Both seeds and tubers are farinaceous and edible. In some places it is known the Indians introduced the plant for food. Professor Charles Goodyear has written an elaborate, plausible argument, illustrated, with many reproductions of sculpture, pottery, and mural painting in the civilized world of the ancients to prove that all decorative ornamental design has been evolved from the sacred Egyptian lotus (Nelumbo Nelumubo), still revered throughout the East (q.v.).
