3. C. stenophyllus. Bigelovia Douglasi, var. steno- 
phylla, A. Gray, Proc. Am. Acad. 1. c. and in part of Syn FI. 
More slender than the two preceding, often taller, the stems 
with perfectly white bark; the narrowly linear acute 1-nerved 
leaves with more or less distinctly serrulate-scabrous mar- 
gins, the whole plant otherwise glabrous: cymes rather 
loose and fastigate: involucre hardly more than 2 lines high 
the oblong obtuse but often mucronate or cuspid-pointed 
bracts rather distinctly 4-ranked: pappus very scabrous, 
almost barbellulate. 
A very definite species peculiar to the eastern base of the 
Sierra Nevada. Almost throughout Western Nevada. In 
writing the Synoptical Flora, Dr. Gray wrongly referred 
here some plants of Utah and New Mexico which are 
very different. 
4. C. Greenei. Bigelovia Greenei, Gray, Proc. Am. 
Acad. xi. 75 (1876); Syn. Fl. 188. Shrub with white bark, 
and ciliolate leaf margins, but lower than the last, the leaves 
larger and twisted: inflorescence more condensed and less 
obviously cymose: heads 3 or 4 lines high and somewhat 
clavate: bracts of the involucre oblong, abruptly subulate- 
tipped 
Species of high plains in Southern Colorado and adjacent 
New Mexico. 
5. C€. eceruminosus. Linosyris ceruminosa, Dur. & 
Hilg. Pac. R. Rep. v. 9, t. 63(1855). Bigelovia ceruminosa, 
A. Gray, Proc. Am. Acad. viii. 643. Often 2 feet high, with 
scattered spreading or recurved leaves and resinous stem; 
the inflorescence obviously cymose: involucre 5 lines high; 
bracts in distinct vertical ranks, narrow lanceolate, abruptly 
produced into a long slender spreading tip. 
Apparently quite local, somewhere near Tejon Pass in 
southern California. 
6. C. elegans. Size and habit of C. pumilus, but the 
very leafy branches of the season straw-colored and gla- 
brous: leaves linear, not spreading, often almost erect,
