Pursh, Fl. 2, p. 602; Nutt. Gen. 2, p. 206. Eastern base of the Sierra Nevada; June 15. 
Flowers monoecious and dioecious. Sepals of ¢ ovate, or rather acute. Moquin (1. c.) asks 
whether the ? flowers are not bibracteate and destitute of a calyx. This is no doubt their 
true structure, and is the view taken of them by Ledebour, (FU. Ross. 3, p. 737.) 
Ertogonum ovauiroLium, Nutt. in Journ. Acad. Se. Phil. 7, p. 51, t. 8, fig. 1. Eucycla oval- 
ifolia, Nutt. 1. c. (n. ser.) 1, p. 166. astern base of the Sierra Nevada; June 15. In our 
solitary specimen there is but a single scape, which is about seven inches high. The leaves 
are broader than in Nuttall’s plant. The filaments are scarcely one-third the length of the 
sepals, and woolly. 
Ertogonum cernuum, Nutt. in Journ. Acad. Sc. Phil. (new ser.) 1, p. 162, 8. PURPURASCENS, 
Eastern base of the Sierra Nevada; June 16. Leaves sometimes almost reniform-orbicular. 
Scape sparingly and trichotomously branching an inch or two above the base. Peduncles pur- 
plish, and involucres glandularly pubescent. Sepals deep rose-color, with pale margins, the exte- 
rior ones somewhat retuse, much longer and broader than the inner ones. Filaments shorter 
than the inner sepals, glabrous. Achenium with a long acuminate point. Embryo curved, the 
radicle elongated, erect. Differs from the ordinary form of E. cernuum, which is much more 
branched, and has white flowers.

Catocnortus Nurratim: stem 2-flowered ; leaves very narrowly linear ; petals obovate-cu- 
neate, rounded at the summit (white, but yellow at the base), with an oblon g dense tuft of hairs 
on the claw ; and just above this a purple spot, with a few scattered hairs. (. luteus, Nutt. in 
Journ. Acad. Philad. 7, p. 51, not of Dougl. Summit of Noble’s Pass, Sierra Nevada; July 
3. We have little doubt of this being Nuttall’s C. luteus, as it agrees exactly with his 
description, and with an imperfect but original specimen of that plant, except that the flower, 
according to Snyder, is white. Mr. N. was uncertain of the color of the flower in his specimen, 
for he says they are ‘‘ apparently sulphur yellow.’’ They are, indeed, yellow at the base even 
in the dried plant, and Mr. Nuttall supposed they were wholly of that color in the fresh state. 
The marking and other characters of the petals are unlike those of Douglas’s C. luteus; and
