Erigeron leiomerus inhabits the alpine regions of 
Colorado, Utah, and Nevada, ascending to eleven 
thousand feet, where it was discovered by Dr. Parry. I 
gathered it in company with Dr. Gray on Gray's Peak, 
and in the Sierra Blanca of the Rocky Mountains in 1877. 
Its habit is that of a dwarf Aster, as may be seen by 
referring to the figure of the Himalayan A. Strachey?, 
Hook. f. (tab, 6912), from which genus frigeron is only 
distinguished by the ray-flowers being in several series. 
The figure here given is that of a plant purchased in 
1895 of Mr. Sindermann, Nurseryman, of Lindau, which 
flowered in the Herbaceous ground of the Royal Gardens, 
Kew, in June of the present year. 
Descr.—A_ glabrous, dwarf, perennial herb, copiously 
branched from the root. Branches about a span long, 
ascending, slender, each bearing a solitary peduncled 
head, leaty from the base to about the middle, and with a 
.°W narrow linear leaves on the peduncle. Leaves spread- 
™g and recurved, an inch to an inch and a half long, very 
narrowly spathulate, narrowed into a petiole, quite entire, 
tip rounded, bright green. Heads about an inch in 
Novesser Isr, 1900.
