BOTANY. 
sessile, oblong-lanceolate, subacute, long, the radical ones more or less 
glabrous beneath, the cauline distant ; racemes elongated or crowded ; calyx 
5-parted, densely hirsute with brownish yellow hairs, lobes lanceolate, acute, 
about equaling the corolla-tube ; corolla white or pinkish, the limb 
broad, exceeding the tube, the throat with 5 prominent scales ; nutlets rugose, 
and granulate-tube rculate between the ridges. — The matured fruit, seen only 
in specimens collected by Stretch near Washoe City, is broadly ovate with 
an abrupt broad strongly incurved apex, somewhat tuberculate-cristate and 
also tuberculate-margined, obscurely transversely rugose. The only difference 
to be found between this and numerous specimens of Plagiohotrys canescens, 
Benth., is in the somewhat more strongly rugose fruit of the latter, and there 
can be little doubt that the two species should be united. California to Wash- 
ington Territory. Foot-hills near Carson City ; April. (855.) 
Eriteichium miceanthum, Torr. Bot. Mex. Bound., 141. Annual, low 
(2-4',) canescently hispid ; stem much and diffusely branched from the base 
upward; leaves Unear, obtuse, 3-6'' long; racemes short, long-bracted ; flow- 
ers crowded ; calyx-lobes linear ; corolla very minute, the throat naked ; 
nutlets oblong, rather acute, very glabrous, convex upon the back, the inter- 
nal angle prominent and sulcate.— The flowers are in short subcapitate 
racemes, sessile, shorter than the foliaceous linear bracts ; corolla white, less 
than 1" long, remaining calyptra-hke after fading, the narrow tube equaling 
the calyx, without appendages, the lobes small and ovate ; nutlets i-l" long, 
shining, adherent to the shghtly longer style by the whole inner angle, in 
tliis respect holding an extreme place in the genus. Indeed it does not differ 
from the genus Krynitzkia, as was observed by Dr. Torrey, except in its 
persistent calyx, while the point of attachment of the seed within the ache- 
nium is even higher than in K. leiocarpa. But a deciduous calyx is by no 
means a constant character in that only species of that genus, and as the 
recognized Eritrichiums vary considerably among themselves in the mode of 
attachment of the seed, and of the achenium to the style, there seems to be 
too little ground for the separation of these two species. Western Texas and 
New Mexico. Found on the sandy shore of Stansbury Island in Salt Lake ; 
June. The roots afford a rich purple dye. (856.) 
Eeiteichium leiocaepum. (Krynitzkia^ F. & M., DC. Prodr. 10. 134. 
See remarks under the last species.) Annual, 6-18' high, hispid ^^ith more 
or less spreading hairs, diffusely branching from the base, the branches elon-
