BOTANY. 
bracteisve minimis oppositis et alternis, sepius 2-3-fidis, segmentis subulatis ; involucris ad nodis 
solitariis sessilibus.”—Gray. 
“ C. Thurberi.” On sandy hill-sides, near San Filipe, where it was first discovered by Mr. 
Thurber, in 1852, May. A remarkable genus of the tribe Eriogoneae, the characters of which 
were drawn by Dr. Gray, and have only been slightly enlarged and modified, as the specimens 
collected hy Dr. Antisell are more complete than those of Mr. Thurber. The plant is from 3-4 
inches high, with a small cluster of spatulate leaves at the base. There are no proper rameal 
leaves, but only bracts, which are often 2-3-cleft, with mucronate segments. The upper 
portion of the involucre is triquetrous ; the 3 processes or horns near the base are widely 
spreading, and usually a little curved. Sometimes there is a fourth smaller horn. I have 
found most of the involucres to contain two flowers.—(Tah. VIII.)
