This is another one of those common and widely dispersed 
species of which I have seen no male plant. 
A. NITIDA. Low, slender, loosely czespitose by short as- 
surgent leafy stolons, the leaves of these little more than 1 
inch long, cuneate-spatulate, obtuse, lustrous-silvery on both 
faces and viscidulous: stem 2 or 3 inches high, somewhat 
woolly, as also the short erect leaves: heads subsessile and 
glomerate: involucre scarcely woolly, some of the outer 
bracts ligulate, wholly chartaceous and greenish, the others 
with ample white tips, those of the outer being narrow, the 
inner successively broader and obovate: bristles of the pap- 
pus (the male only) with narrow terminal dilatation and 
this laciniate below, serrulate above. 
Dry ground on Charlton Island, James’ Bay, Mr. Jas. M. 
Macoun, 8 July, 1887, n. 11272. A peculiar species both as 
to floral characters and in the indument of the mature 
leaves, this being as it were conglutinated into a firm shin- 
ing silvery coat of which the individual hairs are scarcely 
resolvable by the strongest hand lens. Only the male plant 
was collected. 
A. AriZoipES. Very loosely cespitose, the branches rigid, 
stout, ascending, scarcely stolon-like, the leaves forming a 
rosette at summit, these thick and firm in texture, spatulate 
from a broad founded and obtuse terminal portion, perma- 
nently silvery-white on both sides with a dense tomentum, 
not in the least viscid: peduncles an inch high, linear- 
bracted, bearing at summit about 3 small sessile heads; 
Scarious tips of the involucral bracts dull-brownish, those of 
the outer ovate, of the inner obovate: pappus-bristles (only 
the male known) apparently oblanceolate from toward the 
, Serrulate.
