494 CocKERELL: NorrH AMERICAN SPECIES OF HYMENOXYS 
odorata series; the foliage is quite a pale green, the leaves and 
their divisions narrowly linear. One specimen has the basal half 
of the stems dark red. The inner bracts are truncate and _fimbri- 
ate, and have not long points. Hair of achenes ferruginous, varying 
to practically colorless ; pappus-scales colorless, about or a little 
over half length of disc-corolla, decidedly pointed but not aristate. 
Base of disc-corolla densely hairy. Rays 5.75 mm. broad, pale 
orange. 
Only known from the Organ mountains, in southern New 
Mexico. I have examined specimens collected by Vasey and 
several sheets collected by £. O. Wooton in the Organ Mts., at 
5800 ft., July 1897. Professor Wooton also sends me a specimen 
collected by Prof. /. D. Tinsley in Fillmore cafion, Organ Mts., 
Aug. 27, 1897. Without being positive, I believe that H. Vaseyt 
must be the undetermined plant, not in flower, on which the coccid 
Pulvinaria marmorata Ckll. (Entom. 1898 : 130) was discovered. 
“ Hymenoxys Cooperi (Gray) 
Actinella Cooperi Gray, Proc. Am. Acad. 7: 359. 1868. 
Picradenia Cooperi Greene, Pittonia, 3: 272. 1808. 
This species differs from H. Rusbyi by its larger, fewer heads 
and much more lax growth; from H. Vasey by its somewhat 
larger heads, taller growth, and generally less leafy stems. The 
form of H. Cooperi occurring in the Huachuca and Rincon Mts. 
of Arizona is so near H. Vaseyi that I thought at one time to 
reduce the latter to a subspecies, but renewed study convinces me 
that the evidence would not warrant this. Mr. Greenman writes 
me that he has compared Gray’s types of Actinella Coopert and 
Actinella Vaseyi, and believes them distinct. 
I have not seen typical H. Cooperi, except some fragments 
from Gray’s type (from Providence Mountain, Mohave District, 
California, 1860-61, Dr. J. G. Cooper) very kindly sent by Mr. 
Greenman.* These show the achenes densely covered with ferru- 
ginous hair; pappus-scales short as in the other forms, thick, very 
deep ferruginous, with a sort of purplish tint ; rays narrower than 
the Huachuca Mts. plant, and about 6-nerved. Mr. Greenman,
