96 MISSOURI BOTANICAL GARDEN. 
Var. ? PERPLEXANS. — Slenderer, sub-simple or with few 
ascending remotely leafy branches, less glandular, the in- 
florescence sometimes canescent with incurved hairs ; leaves 
scarcely 50 mm. long, divergent, lanceolate, rather obtuse 
and sparingly undulate-serrulate, thin and light green, the 
upper acutely tapering to slender sometimes elongated 
petioles. — Yellowstone Park to Oregon, Colorado, New 
Mexico, and California, apparently more abundant in the 
eastern part of the range. — Specimens examined from the 
Yellowstone, Oregon ( Hall, 176 in part), Colorado ( Wolf, 
1873, 154), New Mexico ( Wright, 1065, in part; Bigelow, 
356), Arizona (Palmer, 1869), Nevada (Truckee Valley, 
Watson, 1867, 395 in part), and California (Rothrock, 
1875, 217; G. R. Vasey, 1880). — Plate 25. 
In aspect somewhat resembling #. Californicum, to 
which, perhaps, it is to be joined; but with the incurved 
pubescence of #. Fendleri and other relatives of adenocau- 
Jon on the flower-buds, etc. (which in some specimens are 
very cinereous ), and more closely connected by intermediate 
forms with adenocaulon than with any other species. 
20. E. Catrrornicum, Hausskn. — Tall, rather slender, 
somewhat branched, glabrous below, the inflorescence and 
buds white with long and rather coarse ascending hairs ; 
leaves often 75 to 100 mm. long, lanceolate, subacute, 
rather remotely serrulate, rounded or acutely tapering to 
short petioles, soon glabrous; flowers comparatively few; 
fruiting peduncles slender, sometimes nearly equalling the 
leaves; capsules at length nearly glabrous; seeds almost 
beakless, .4 x .9mm.; coma white.— Monogr. 260. — Cali- 
fornia: (Near the Russian settlement, Wrangell, 1833, fide 
authentic Californian specimens, for the privilege of examining which I 
am indebted to Professor Greene and Dr. Britton, possess larger flowers 
with broad prominently 4-lobed stigmas. The specimen from Mr. Drew 
in the Columbia College Herbarium has innovations in form of open 
turions with decidedly fleshy scales, in this respect approaching 
E. boreale. It is quite unlike any of the species characterized by a 4-lobed 
stigma, and may, perhaps, prove to be a hybrid. — Plate 24.
