collected by Aven Nelson at the head of Green river, Aug. 14, 1894, 
no. 885. This is far from being typical. The leaves are narrowly 
oblanceolate, and the pistillate bracts are hardly obtuse. More mate- 
tial of this might prove it to be entirely distinct. 
ANTENNARIA ApRICA Greene, Pitt. 3:274.—This excellent species is 
common in the foothills of the Laramie and Medicine Bow mountains, 
flowering early in the spring on sunny slopes. Many of our specimens 
have pinkish bracts (pistillate), and often as many as 14 heads ina 
cluster. The following are the specimens in the herbarium : no, 1269, 
Centennial valley, June 9, 1895; no. 149, Pole creek, June 3, 1894; 
Inyan Kara divide Aug. 29, 1892 (B. C. Buffum); no. 4347, Plumbago 
cafion, June 9g, 1808.

’ Antennaria arida, n. sp.— Cespitose, in dense mats formed by the 
numerous short (1% high) ascending sterile branches: stems 10-15" 
high, slender, wiry, weak above, the subcapitate cluster frequently nod: 
ding, loosely covered with shreddy wool : leaves crowded, spatulate, i 
acutish, 0.8-1™ long, densely and permanently hoary tomentose 08 
both sides, inclined to be conduplicate and noticeably so in the younger 
leaves ; cauline leaves oblong linear, acute, lightly hoary-tomentos 
more or less twisted and curved: heads 6™" high, sessile, 6-10 m@ 
subcapitate cluster : involucres turbinate ; bracts (pistillate) in about a 
two series, all obtuse, scarious portion oblong, milk-white, occasionally 
the outer with a purplish streak. ae 
A remarkably distinct species, from the arid region of soullme 
Wyoming. Type in Herb. Univ. of Wyo., no. 4798, collected by Aver x

‘Antennaria scariosa, n. sp.— Cespitose, lightly hoary tomentose : 
throughout : stems 3-6 high ; stolons short, at most 4™ long: [eave 
1.4™ long or less, spatulate, obtuse or acutish, inclined to b¢ set 
duplicate; cauline leaves rather ample, oblanceolate varying to ree 
rowly oblong, occasionally the lowest spatulate: heads 6” high, rt 
6-8 in a subcapitate leafy-bracted cluster; bracts (pistillate) sis 
conspicuously scarious, all obtuse, the scarious portion milk-W : 
elliptic to obovate. ; Ss : 
In its floral character this is very closely allied to A. arida, era - 
in its broader bracts. 4. scariosa differs from that species, also; a 
smaller size, its more prostrate habit, its larger radical leaves, and in al * 
ample cauline ones, which are never twisted. It also seems to be T
