Indian Cucumber-root (Medeola virginiana) is a common woodland plant, but the flowers are so inconspicuous that they are often overlooked; in fact they are often nodding below the upper leaves so as to be invisible. The stem is tall and slender, ranging from 1 to 3 feet in height; it rises from a thick horizontal rootstalk, having a taste similar to that of the cucumber. A whorl of from five to nine ovate-lanceolate, pointed leaves is located midway on the stem; at the top, three smaller but similarly shaped leaves radiate. Above these, or it may be below, because of the curving pedicels, are three flowers. They are pale greenish-yellow; the three sepals and three petals composing the perianth are very much reflexed or curled; they have six stamens each, and one style dividing into three purplish-brown, recurved stigmas.
It is said that the Indians formerly used the roots for food; at the present time they are used for various medicinal preparations. Cucumber-root is found from N. B. to Manitoba and southward to the Gulf, flowering in rich woods during May and June.
Genus (Trillium)
Trilliums derive their generic name from the fact that all their parts are arranged in threes; three leaves, three petals, three sepals, and a three-parted stigma. The common name of Wake Robin was probably early given because these flowers appear at an early date. As a matter of fact they do not bloom until weeks after the robins have returned to the Northern States. All the purple trilliums have an unpleasant odor resembling that of putrid meat; as they are largely dependent for fertilization upon certain carrion flies, it is very probable that their peculiar color is for the purpose of an added lure for these insects.
Purple Trillium; Birthroot; Ill-scented Wake Robin (Trillium erectum) has three purplish-brown petals and three sepals; six stamens exceeding in length the stout spreading stigma. Flower solitary, rising on a short pedicel above the whorl of broad, ovate, pointed, and short petioled leaves. This trillium ranges in height from 6 to 15 inches. It flowers in April and May, in rich woods from Quebec to Ont. and southward.
(A) Large-flowered Trillium (Trillium grandiflorum) is the largest of the genus in all respects and is one of the best known and most common species. It can be looked for in any damp, rich woods during May or June. Usually they grow in colonies and it is an exception when one finds a single plant without others being in sight. The stem of this species is from 10 to 18 inches in height; the waxy-white petals are from 1½ to 2 in. in length; as they grow older the color changes to a delicate pink and they curve gracefully backward.
The flower is on a short pedicel above the whorl of broad, ovate-pointed, and short petioled leaves. Found from Vt. to Minn. and southward to N. C. and Mo.
