284 PITTONIA. 
I have long neglected to define a certain new Antennaria 
distributed from Montana by Mr. Rydberg as representing 
my A. foliacea. I may call this 
A. OXYPHYLLA. Stolons short, densly leafy with rather 
small spatulate-obovate and oblanceolate leaves, these densely 
silky-tomentose beneath, less so above: flowering stems a 
foot high more or less, purplish underneath a scanty inves- 
titure of somewhat flocculent or arachnoid silky wool, and 
this ultimately more or less deciduous: stem-leaves many, as 
long as those of the stolons but narrow, narrowly oblanceolate 
to linear, cuspidately acute: corymbs in the pistillate plant 
rather dense, polycephalous: outer bracts of involucre 
brownish at base, their white tips short, obtusish, those of 
the several other series with more elongated tips successively 
ovate, ovate-lanceolate and linear-lanceolate, all acute and 
of a rather dull white. 
Spanish Basin, Gallatin Co., Montana, n. 5,148 of Ryd- 
. berg & Bessey's 1897 collection. Plant very different from 
the real A. foliacea, the cauline leaves far less ample.
