Antennaria eucosma is a remarkable plant, combining character- 
istics of the A. plantaginifolia group of species with those of 4. car- 
patica and its allies. It differs at a glance from all the species of 
the former series by its very elongate upright lanceolate leaves which 
closely match those of A. pulcherrima (Hook.) Greene, a Rocky 
Mountain species allied to the Old World A. carpatica (Wahl.) R. Br. 
From A. pulcherrima, A. lanata (Hook.) Greene (also of northwestern 
America), and A. carpatica it is distinguished at once by its slender 
elongate rootstock and slender horizontal stolons. From A. pul- 
cherrima, which it resembles in foliage and pubescence, it is further 
distinguished by its fewer larger pistillate heads with long dark in- 
volucral bracts, its smaller staminate heads with less dilated and more 
uniformly toothed pappus-bristles; from A. lanata by its sericeous 
pubescence, larger pistillate heads with brown rather than lead- 
colored bracts; and from A. carpatica by its much larger habit, 
broader uniformly sericeous 3-nerved leaves, larger heads with brown 
involucres, etc. 
An old specimen in the Gray Herbarium collected on Anticosti 
by Pursh is apparently referable to this species, but the material is 
inadequate for final determination. This is presumably the plant 
referred to by Hooker as his A. carpatica, a, humilis (Hook. Fl. Bor.- 
Am. i. 329), but Hooker's description and bibliographic citations 
show his var. humilis to be typical A. carpatica. The Anticosti 
plant was likewise referred by Gray (Syn. Fl. i. pt. 2, 232) to true 
Á. carpatica. 
ANTENNARIA ALPINA (L.) R. Br., var. cana, n. var., foliis utrinque 
sericeo-tomentosis, tomento denso cano. 
Like typical A. alpina but with the leaves permanently whitened 
on both sides with a close silvery tomentum.— A. alpina, var.—, 
Hartman, Skand. Fl. ed. 11, 13 (1879).— Apparently rare in Scandi- 
navia, where the true 4. alpina, with the leaves bright green and 
glabrous or glabrate above, is the common form of the species; but 
apparently largely replacing in eastern America the typical green- 
leaved plant. The following specimens have been examined by us.
