A FASCICLE OF NEW COMPOSITA. 59 
writer, in the same general region, namely, in the mountains 
near Silver City, New Mexico, 18 May, 1880, and distributed 
for Z. flagellaris. The species last named has a rather obscure, 
fine closely appressed hairiness. That of the new one is so ex- 
tremely different, that were the plants of the size of a Sunflower 
or Goldenrod, no botanist would confuse them as one species, 
were the pubescence the only character. I may remark that 
true Æ. flagellaris reaches the mountains of even southern New 
Mexico, where, however, it occurs only in a more elevated bio- 
logical zone. 
ERIGERON Tracyi. Allied to the last but dwarf, only 2 or 3 
inches high, densely leafy at base and with no stolons (at least 
at flowering time): petioles of the spatulate-lanceolate entire 
leaves shorter than the blade or obsolete; the whole herbage 
silvery-hoary with a fine dense strigulose pubescence, or this 
more sparse and spreading on the solitary scapiform peduncle : 
involucre hispidulous: outer pappus very conspicuous though 
consisting of only shorter and setiform hairs, the inner of a few 
very delicate capillary ones. 
Davis Mountains, western Texas, Tracy and Earle, 28 April, 
1902. ; 
CHRYSOTHAMNUS ee Near C. elegans, about twice 
as large in all its parts, a foot high or more; branches of the 
season with almost shining white bark, and dull light-green 
foliage: leaves linear, suberect, coriaceous, 14 inches long, 
scarcely twisted, rather faintly 1-nerved, glabrous, or the margin 
scabrous-ciliolate: heads large (for this group), in dense and 
rather large corymbose panicles; bracts of involucre in 4 series, 
carinate-conduplicate, pungently acute, glabrous, scarcely glutin- 
ous: throat of corolla cleft to below the middle and the 
Segments spreading ; style-tips scarcely more than subulate, 
hirtellous: achenes cuneate-oblong, rather coarsely appressed- 
pubescent, the scanty pappus of about the same length. 
Collected only by the writer, near Grand Junction, Colorado, 
2% August, 1896. es Mee S
