only 4-5°". 
No. 6341, Teton mountains, August 16, 1899. 
Antennaria fusca.— Loosely cespitose : stolons about 5 long: stems 
slender, 12™ high or less: leaves canescent or tomentulose on both 
sides, the older ones becoming glabrous ; the radical and those of the 
stolons spatulate, indistinctly mucronate, 15-22™ long; the cauline 
linear, 2~4"" wide, the lower somewhat broadened upwards and acute, 
the upper acuminate : heads 3-13, on short pedicels in close clusters or 
loosely corymbose, and the head or heads of the lowest pedicel, which 
is often 2-3 long, usually overtopping the rest: involucres about 6™™ 
high: bracts (pistillate) in about two series, the lower half bright green 
and sparsely woolly, the upper portion brown or greenish-brown, 
oblong, obtuse, more or less serrate. 
In habit and general appearance the species here described would sug- 
8est A. aprica Greene, yet it is not even a very near ally of that. Its dark- 
colored bracts, slender stems, and the dull and light indument of the leaves 
easily separate it specifically from Professor Greene's species. 
The type is no, 6356, growing on dry bottoms and in open woods on 
Lewis river, Yellowstone park, August 8, 1899. 
tennaria oblancifolia.— Cespitose : stolons very short: stems slen-

Narrowly so, acute, mucronate, about 2™ long, sparsely canescent to

Close racemose or paniculate clusters : involucres (staminate) 4™ high, 
the herbaceous portion of the bracts sparsely woolly, the scarious por-
