110 ERYTHEA. 
Evidently a rare plant of northern Idaho or some neigh- 
boring region, which as late-as 1873, according to Gray, had 
been collected only by Nuttall and by Burke; in the Botany 
of the California State Survey, he wrongly referred here a 
certain shrub of the Sierra Nevada which had been collected 
by myself. 
Var. gnaphalodes. Bigelovia graveolens var. hololeuca. 
A. Gray, 1. ¢. (1873)? Very tall, often 5 feet high, the 
whole shrub, even to the involucre, white with woolly 
tomentum ; bracts often 4 in each vertical rank, margins not 
ciliate : throat of corolla claviform, the teeth only a fourth its 
length : corolla-tube not hairy. 
Common in the deserts of middle and southern Nevada, 
from Pyramid Lake, Mrs. Curran, to Esmerelda Co., 
Mr. Shockley. The type of Gray’s var. hololeuca was from 
Owen’s valley, within the borders of California ; but to this 
was assigned a cobwebby hairy corolla tube, just the 
character of var. albicaulis, perhaps by mistake. 
Var.(?) latisquameus. Bigelovia graveolens, var. latis- 
quamea, A. Gray, 1.c. Tall, white-tomentose as to stem and 
foliage, but involucre less so : leaves fewer and shorter than 
in other forms, the inflorescence fastigiate, more open : inner 
bracts broad, thin, very obtuse: throat of the corolla shorter 
and broader, the teeth very short: pappus permanently 
white. 
Southern New Mexico, near the old copper mines, Bigelow, 
Henry, and the present writer. Probably a distinct species. 
Var. (?) Arizonieus. Talland very stout, rather sparingly 
leafy, very white and tomentose : leaves 1 or 2 inches long, 
narrowly linear : outer tracts of involucre tomentose, acute, 
the inner obtuse : very slender corolla tube with a few clavel- 
late spreading hairs ; throat campanulate-funnelform, hardly 
more than a fourth as long as the tube and cleft rather 
deeply.
