the base of the involucres: bracts (pistillate) imbricated, in about four 
series, pinkish, all more or less serrulate, the outer very broad and 
obtuse, the innermost narrow and acute. 
It differs from A. Jarvifolia in its larger, less silvery leaves, and in its much 
broader pistillate bracts. From A. fo/acea it is readily distinguished by its 
less ample cauline leaves, its much larger heads and its pluriserial bracts.

fork of Crow creek in the Laramie hills, July 11, 1896 (Elias Nelson). 
’Antennaria corymbosa, n. sp.— Stems erect, 25 high, with numer 
ous ascending or assurgent sterile branches at base: leaves thin, 
sparsely tomentose, 1-nerved or indistinctly 3-nerved, narrowly oblan 
ceolate, tapering gradually into a slender petiole, 3—3.5 long (includ: 
ing petiole); cauline leaves shorter, linear, acuminate: heads small, 
4-5™ high, in a rather close corymbose cyme, the lowest pedicel 
usually surpassing the others in length: involucres woolly with cob- 
webby hairs ; bracts (pistillate) in about three series, oblanceolate, 
obtuse or the innermost acutish, a brown spot above the greenish por- 
tion, tips white. 
A well marked species, evidently closely related to A. pedicellata, from 
which it differs in its obviously nerved and much less conspicuous sie: 
Its woolly, cobwebby involucres and the brown middle portion of its bre 
give a characteristic appearance.
