NEW OR NOTEWORTHY SPECIES. 25 
- terminal eymose corymb of which the lateral branchlets 
surpass the terminal: involucre only 3 or 4 lines high, its 
bracts few but very unequal, not in vertical ranks, the inner 
= thin, obtuse, the middle ones with abruptly acute herbaceous 
_ tips, the outer and very short ones herbaceous throughout : 
- corollas deeply cleft; style-tips linear-subulate, only tardily 
exserted : achenes linear, villous-hirsute. 
In moist alkaline soil, plentiful along a streamlet near 
Rock Springs, Wyoming, 9 August, 1895. A species of most 
3 unusual habitat, all the others inhabiting dry plains or stony 
hills. The tall slender willowy stems are algo very unlike 
those of any other species of the genus. - It is very possibly 
3 quite local, though certainly abundant in its locality. 
ERIGERON TENUISSIMUS. Perennial, very slender, 2 feet 
- high or more, simple below, equally leafy up to the inflo- 
- rescence, nearly glabrous: leaves filiform, 1 or 2 inches long ; 
_ flowering branches at summit of the stem almost racemosely 
-. disposed, divaricate, or even somewhat deflexed, each hav- 
E ing one or twosmall heads: bracts of the broadly campanu- 
- late involucre in 2 or 3 not very unequal series, the outer 
- onesstrigose-pubescent: rays 30 or more, purplish or bluish : 
- achenes oblong-linear, compressed, nearly glabrous. 
Near Ventura, California, June, 1893, Miss Anita Symmes.! 
1 Related to E. foliosus, but the leaves absolutely filiform, and 
. the character of the branching most peculiar. 
Ericeron Brocumans#. Perennial, very stout, equably 
E leafy up to the close terminal corymb of large purple-rayed 
heads: stem strongly striate and, with the spatulate-linear 
leaves, canescently hispidulous; the main cauline leaves 2 
inches long or more, each with a short very leafy branch in 
its axil: corymb of 12 to 20 rather short-peduncled heads, 
these more than 4 inch high, little less than $ inch broad:
