Esmeralda county, Nevada ( Shockley), western central Cali- 
fornia, and Oregon (Hall, and N. W. Bound. Surv.).— 
Plate 15. 
The larger, more glabrous and compound form, figured 
by Barbey & Cuisin, approaches the usual Pacific variety 
of adenocaulon, the flowers of which are sometimes rather 
large but more loosely arranged. Specimens collected by 
Macoun on Vancouver Island and in the Rocky Mountains 
of British Columbia, are doubtfully referred here, though 
they may belong to adenocaulon. The smaller, more closely 
crisp-hairy form approaches the next species, and is well 
represented by Hall, no. 177 a, from Oregon. A curious 
simple plant with large glossy thin leaves, scarcely to be 
referred elsewhere, occurs from Queen Charlotte’s Islands, 
B. C. (Dawson, July 10, 1878, no. 1932 in hb. Macoun. ) 
14, E. Warsonr, Barbey. — Becoming a foot and a half 
high, with less marked lines, softly crisp-downy through- 
out; leaves elliptical, rather obtuse, slightly denticulate, 
rounded to short winged petioles ; flowers not very numer- 
ous, suberect, in the axils of the gradually reduced more 
lanceolate and acute upper leaves; seeds coarsely papillate, 
.38x 1.25 mm., barely umbonate at top; coma dingy. — 
Brewer & Watson, Bot. Calif. i. (1876), 219; Haussknecht, 
Monogr. 263; Barbey & Cuisin, pl. 6. — Various parts of 
California, jide Haussknecht.— Known to me with cer- 
tainty only in the original specimens in Hb. Gray. from 
the Russian settlement, but young plants from Mariposa 
county ( Congdon, 1890) can hardly be referred elsewhere. 
What commonly passes for this is the preceding species. — 
Plate 16. 
= = Petals3 to 5 mm. long, pale to mostly rather deep rose-colored: 
leaves for the most part alternate: otherwise like the preceding group. 
a. Narrow-leaved for the group. 
15. E. HOLOSERICEUM, n. sp. — Rather woody, loosely 
branched, at least the upper leaves and branches canescent 
with subappressed hairs; leaves 50 mm. long, rather re-
