Antennaria alpina (L.) Gaertn. Fr. & Sem. 2. 410. 1791. 



Gnaphaliiini alpinum L. Sp. PL 856. 1753. 



A. alpina is characterized by the bracts of the pistillate head, 

 which are dark greenish brown, lanceolate and acute. The stam- 

 inate plant is exceedingly rare ; in the Columbia herbarium there 

 are only three small plants, two, both monocephalous, collected by 

 M. W. Harrington in Alaska, and the third received from Dr. 

 Hooker, without any reference to locality or collector. 



A. alpina has been collected in Montana by J. H. Flodman on 

 Yogo Baldy, August 24, 1896, no. 861 ; Long Baldy, August 19, 

 no. 862, and by Frank Tweedy in the Bozeman Pass, 1883. 



Antennaria umbrinella n. sp. 



Stem generally about i dm. high ; leaves of the stolons spatu- 

 late, I-I.5 cm. long, those of the stem linear-oblong; heads small, 

 about .5 cm. high, conglomerated in small subcapitate clusters ; 

 scarious portion of the bracts in the pistillate head oblong, obtuse, 

 in the outer varying from umber to isabel-colored, in the inner 

 lighter colored and sometimes almost white; in the staminate 

 heads all elliptic, obtuse and isabel-colored or yellowish white. 



In habit it much resembles A. alpina, from which it differs by 

 the oblong obtuse bracts of the pistillate plants and somewhat 

 smaller heads. The staminate plants of the two species are almost 

 identical in every respect except that the bracts are of slightly 

 lighter color in A. umbrinella. I describe this species as new, 

 with some hesitation, not that I have any doubt concerning its 

 distinctness from A. alpina and our North American species, but 

 it is so closely similar to A. Magellanica Sch. Bip.* that if it were 

 not for the great distance between their ranges and for the slightly 

 longer leaves and more slender caudex of the latter, I would re- 

 gard the two as one species. The staminate plants are nearly as 

 common as the pistillate ones. The following specimens are in the 

 Columbia herbarium : 



Montana: J. H. Flodman, no, 859, August 19, 1896, from 

 Long Baldy in the Little Belt Mountains (type) and no. 860, 

 July 18, from Spanish Basin. 



Wyoming: Aven Nelson, no. 885, 1894 (labelled A. dioica). 



Nevada: S. Watson, no. 650 {A. alpina) and 651, 1868.
