STUDIES IN THE COMPOSITJE. 295 
Eastern Oregon, at 5000 to 6000 feet in the mountains, 
W. C. Cusick (n. 1771) A very interesting, yet trouble- 
some plant, intermediate, as it were, between E. salsuginosus 
and Aster Cusickii, and with far more likeness to Aster than 
to Erigeron. 
E. eximius. Stems mostly several from a small branch- 
ing crown or caudex, slender but rather rigid, 10 to 16 
inches high, with few and scattered leaves ; herbage glabrous 
and glaucescent, except that the leaf-margins are sparsely 
hirsute'ciliate and the upper part of the stem and the pe- 
duncles rather densely granular-glandular, and with a few 
short spreading hairs: all the leaves perfectly entire, the 
tufted basal ones with spatulate-oblong obtuse blade and 
slender petiole; the cauline from oblanceolate to spatulate 
and lanceolate, the middle and uppermost sessile : heads 4 
‘to 9 (rarely 1 or 2), on slender rigid naked peduncles: 
bracts of the large involucre few and broad (only about 20), 
lanceolate, viscid-granular throughout, and only the very 
base hirsute: rays numerous and narrow, $ inch long or 
more, lilac-purple to rose-purple, rarely white. 
Species abundant in pine woods below Marshall Pass, 
Colorado, and particularly on the lower slopes of Little 
Ouray Mountain in the same region, in rather dry ground; 
the allied, yet very different, E. Coulteri being as common in 
more moist and shady situations in the same district. 
E. Drummonpu.. E. glabellus, var. pubescens, Hook. Fl. 
ii. 19. Size of E. glabellus, but stems apparently solitary 
rather than clustered, and strietly erect, the whole plant 
somewhat cinereous with a roughish hirsutulous pubescence, 
; this spreading or even retrorse on the striate stem, but some- 
= What appressed on the foliage: leaves from broadly to nar- 
rowly oblanceolate, all very acute, mostly with a few salient 
Serratures: heads 1 to 4, large, with numerous and narrow 
5 long rich purple rays; the involucre hemispherical, not more 
_ pubescent than other parts of the plant.
