North America. In that species the leaves are green and 
glabrate above, and its involucre is very unlike that of our 
plant, its bracts being much broader, shorter and less pointed. 
The radical leaves in A. lanata, as compared with those of 
A. pulcherrima, are small and nerveless; the tips of its in- 
volueral bracts in the male are broad, obovate, and very ob- 
tuse, while in the female the herbaceous body of the bractis 
greatly narrowed and elongated, and with a narrow white 
tip. A. pulcherrima inhabits low boggy places, at least in 
the far North, while A. lanata is of more elevated and com- 
paratively dry slopes. It is in the Canadian Survey Collec- 
tion under the following numbers: 11253, from grassy slopes 
at 6000 ft. altitude in British Columbia, and mountains north 
of Griffin Lake, in the same region ; 11251, from mountains 
at Warm Springs, Kootanie Lake, these by John Macoun. 
Also n. 11255, from summit of Kootanie Pass, in rather 
sterile soil, collected by Dawson; and again, n. 11250, from 
alpine slopes at 7000 ft. near Kicking Horse Lake, John Ma- 
coun. 
3. Some southwestern species of ANTENNARIA. 
The study of the northern species has led, incidentally, to 
a careful examination of the few southwestern representa- 
tives of this genus, with the following results. í 
A. ROSULATA (Rydb.?) Depressed-czespitose, the numer- 
ous rather coarse and subligneous branches forming a broad 
mat covered with many short densely leafy stolons: leaves 
ł to inch long, from spatulate-obovate to obovate-lanceo- 
late, acutish, silvery white with long appressed pubescence: 
heads 1 to 3, on peduncles only } to 3 inch long: involucral 
bracts in the male plant mostly lanceolate and subcoriaceous 
throughout, or only the acutish tips scarious; those of the 
male with larger obovate obtuse or retuse and nearly as long
