ANTENNARIA ALPINA (L.) Gaertn. Fr. & Sem. 2: 410. 1791. 
Gnaphalium 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. 
¥ ANTENNAKIA UMBRINELLA Nn. Sp. 
Stem generally about 1 dm. high; leaves of the stolons spatu- 
late, I-1.5 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. a/fina 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. dwica). 
Nevada: S. Watson, no. 650 (A. alpina) and 651, 1868.
