1904] NELSON; ROCKY MOUNTAIN PLANTS 277 
head: involucre turbinate-campanulate, about 1™ high, shorter 
than the disk; its bracts in two series, the outer broadly linear, 
short-acuminate, minutely glandular, the inner narrower, sub- 
scarious: rays orange-yellow, obscurely 3-toothed: disk corollas 
with narrow minutely pubescent tube as long as the gradually 
dilated throat: akenes linear, dark, sparsely hispidulous. 
After deliberating on this for a long time and failing to decide upon even 
its nearest ally, I submitted it to Dr. Greene, who replied as follows: ‘“ This 
I can refer to no known species ; yet it is a feeble thing as to any character.” 
Nevertheless, it seems well to place it on record and to distribute to the her- 
baria specimens which will enable our students to pe a for themselves 
whether it is.a species with “feeble ’’ characters or not. 
e type is no. 377, from Doyle Creek, Big Horn Mountains, Wyo., July 
26, 1902; collected by Mr. Goodding. 
’ Tetradymia axillaris, n. sp—A shrub mostly less than 1” 
high: stems several from the base, these freely and somewhat 
fastigiately branched at summit, all very white with a close fine 
permanent pannose tomentum: spines widely divaricate but not 
reflexed, very straight, slender, rigid and’ pungently acute, 2-4™ 
long, tomentum somewhat floccose and rather early deciduous: 
leaves fascicled in axils of the spines, green and glabrous, some- 
what fleshy, linear subulate, very unequal, 5-12™" long: heads 
solitary, axillary, 5-flowered, on glabrous peduncles as long as 
the oblong-cylindrical head: bracts of the involucre 5, about 
1™ long, somewhat carinate and rigid, glabrous: pappus bristles 
much surpassing the copious hairs of the akene. 
This relative of 7. sfinosa Hook. & Arn. I was at first inclined to refer to 
Jones’s var, longispina of that species. With that variety it has some points 
in common, but because of the relatively long internodes of the stems, the 
Straight rigid spines which are 3-5 times as long as the fascicled leaves, 
the glabrous heads, and peduncles which are solitary in the axils, it seems as 
impossible to unite it with that variety as with the species. 
€ type no. 917 is from Meadow Valley, Wash., southern Nevada, col- 
lected by Mr. Goodding, May 2 22, 1902.
