SOME CANADIAN ANTENNARIAS. III. 



By Edward L. Greene. 



In the May issue of the Naturalist for 1904, I remarked 

 how plainly British Columbia was being indicated as the centre 

 of distribution for the genus Antennaria on the Pacific slope 

 of the continent. And now, another ample collection of these 

 plants, made there in the summer of 1905 by Mr. James M. Ma- 

 coun, strongly confirms the opinion then expressed. No fewer 

 than three of his numbers seem to represent species quite new ; 

 while others of them are almost as welcome as completing our 

 knowledge of seme that were hitherto known but imperfectly. 



A. eximia. Stems stoutish a foot high more or less, erect, 

 above a slightly decumbent base, the basal stolons short, densely 

 leafy, their leaves not large for the plant, about 1 1-2 inches 

 long, narrowly obovate-cuneiform, mucronate, thinnish, rather 

 loosely and silkily lanate beneath, above bright green, glabrous, 

 minutely whitish-puncticulate, very narrowly white-margined by 

 extension of the wool of the lower face ; stem-leaves many and 

 apprcximate, the lowest quite as large as those of the stolons but 

 narrower, oblong-cuneiform ; heads many and large, forming 

 an ample compound corymb 2 or 2 1-2 inches wide across the sum- 

 mit ; involucre much imbricated, its cuter bracts arachnoid- 

 woolly and greenish, with short scarious tips or none; the inner 

 successively obtusely and then acutely or acuminately scarious- 

 tipped. Male plant unknown. 



Skagit Valley, 12 July, 1905. Geol. Surv. n. 69,338. Mr. 

 Macoun gives for this the habitat of open sandy woods, through 

 which fire had repeatedly run, at 2500 feet altitude; and I note 

 in the specimens evidence that it grews in beds of moss of the 

 genus Polytricluim. It is a handsome species, apparently re- 

 lated to the next, though much larger.
