Purshia tridentata formed a conspicuous object in several parts of theroute, not only east of the mountains, but in Oregon and California. Itis covered with a profusion of yellow flowers, and is quite ornamental.Sometimes it attains the height of twelve feet. Spirsea ariaefolia, var. discolor, was found on the upper waters of thePlatte, holding its characters so well that it should perhaps be regarded asa distinct species. Oenothera clav-Eformis. Torr. and Frim. Leaves ovate or oblong, denticulate or toothed, pinnatified at the base,with a long naked petiole; scape with several small leaves, S—12-flowered;segments of the calyx longer than the tube; capsules clavate-cylindrical,nearly twice as long as the pedicel. Flowers about as large as in CE. pu-mila. Grows with the preceding. * In Hookers Journal of Botany, iv, p. 351. ■ HOT.WY Plate I

Annual; canescently strigose ; stem low and stout; leaves rhombicovate,repandly denticulate, acute ; flowers (large) clustered at the summit of theshort stem; tube of the calyx nearly twice the length of the segments; pe-tals entire, one-third longer than the slightly declined stamens; anthers verylong, fixed by the middle; style exserted; capsules prismatic cylindrical. Allied to CE. Jamesii, Torr. and Gr., and belongs, like that species, tothe section Eucenothera and sub-section Onagra. (Enothera canescens. Torr. and Frem. Strigosely canescent; leaves narrowly lanceolate, rather obtuse, remotelydenticulate ; flowers in a leafy raceme; tube of the calyx rather slender,three times as long as the ovary, and one-third longer than the segments;petals broadly ovate, entire.
