STUDIES IN THE COMPOSITA. 215 
appear to have been collected in any part of Canada, though 
one can hardly doubt the possibility of its being found 
somewbere along the southern borders of that country. 
A. CANADENsIS. Of the size and general aspect of A. 
neglecta, but the stolons less elongated, assurgent rather than 
procumbent; leaves as long, as narrow, quite as destitute of 
venation, but acute at apex, and far less spatulate, i. e., more 
. distinctly differentiated into blade and petiole: bracts of in- 
voluere all narrower, much less conspicuously and differently 
tipped, the chartaceous body of the bract more naked (as to 
wool), much longer, and in the innermost very narrow ones 
produced upward almost to the summit, this only margin- 
ally white, and acuminate. 
A Northeast Canadian homologue of A. neglecta; neces- 
sarily held distinct from it on account of its very different 
involuere; though as indicated, the habit and the foliage 
are also, in a degree peculiar. The male plant is not known 
tome. The female is beautifully exemplified in the Cana- 
dian Survey collection by sheets n. 11293, from Lake Mistas- 
sini; 11285, from Prince Edward Island; 11294, from Jupiter 
_ River, Anticosti, and n. 11299, from Campbellton, New 
Brunswick, this last collected by R. Chalmers, all the others 
‘by the Messrs. Macoun. 
A. CAMPESTRIS, Rydb. Bull. Torr. Club, xxiv. 304. Spe- 
cies well defined by Mr. Rydberg, yet apparently known to 
him chiefly from along the southern limits of its range. 
From the Canadian Survey collection it appears as if it were 
plentiful on the bleak plains of middle and western British 
America. In that collection the following numbers belong 
to it: 12276, from rocky fields, Stonewall, Manitoba, Macoun, 
2 June, 1896; 11290, in dry gravelly soil, Souris Plain, As- 
Siniboia, Macoun, 28 June, 1883; 13941, on the open prairie, 
Prince Albert, Saskatchewan, Macoun, 30 June, 1896; 14373, 
from the open prairie, Indian Head, Assiniboia, Spreadbor- 
ough, June, 1892.
