DESCRIPTION AND DISTRIBUTION OF THE PLANT.* Zygadenus elegans, shown in Plate III, is an erect perennial herb with leafy stems arising from coated bulbs. Often numerous bulbs are together, forming clumps; three are so grouped in the picture. The linear grasslike leaves are one-sixth to one-half inch broad, 4 to 12 inches long, and are much whitened, particularly when young; the lower ones are sheathing at base, the upper without sheaths.

DESCRIPTION AND DISTRIBUTION OF THE PLANT.* Zygadenus elegans, shown in Plate III, is an erect perennial herb with leafy stems arising from coated bulbs. Often numerous bulbs are together, forming clumps; three are so grouped in the picture. The linear grasslike leaves are one-sixth to one-half inch broad, 4 to 12 inches long, and are much whitened, particularly when young; the lower ones are sheathing at base, the upper without sheaths. The flowers are in racemes which are simple or somewhat branched below, and often few-flowered. Under the flowers are ovate-lanceo- late purplish bracts. The greenish straw- colored or whitish flower segments are one-fourth to five- twelfths of an inch in length and adhere to the base of the ovary. The glands of the upper flower segments are obcordate. The ovary is ovate in form and the stamens are included. In the western part of the United States (figure 5) this plant ranges from the Olympic Mountains, Washington, east to central Montana and southward through central Oregon and central Nevada to southern Arizona and east to central New Mexico. In this region it is a high-mountain plant ranging from 2,500 to 13,000 feet. The natural habitat of Z. elegans is moist meadows and springy places from the yellow-pine to the arctic-alpine zones. Near the Salina Experiment Station the plant buds early in July, is in flower from the middle of July, and seeds in August and September. Distinction hetween Z. paniculatus and Z. elegans.—The technical description already given will serve to distinguish clearly the two species treated of in this bulletin. The stockman, however, using the country within the range of these plants, can readily separate.
