^°^ The Ottawa Naturalist. [March 



almost a petiole, green and nearly glabrous above, this face quite 

 glabrous in age; cauline leaves spreading: cyme of 8 to 12 heads 

 rather compact, the short slender pedicels less woolly, greenish 

 and viscid : heads subcampanulate, much imbricated, the outer- 

 most bracts oval, the next longer but very obtuse, only the inner 

 lance-linear, not even these very distinctly scarious-tipped, nor 

 even the outermost notably woolly, all of a satiny light-greenish 

 hue. 



Chilliwack Valley, at 3,500 ft., 8 Aug , 1901, by Mr. Macoun, 

 No. 26,186. Remarkable for the greenish and glossy involucres, 

 more like those of certain Gnaphaliums than of any other 

 Antennaria. 



A. acuminata. Obviously suffrutescent, but the ascending 

 woody and naked basal branches slender and not rigid ; flowering 

 branches 9 to 12 inches high and slender; stolons also slender, 

 long and sparsely leafy, their leaves about i ;54^ to i >< inches long, 

 narrowly spatulate, very acute, thinnish, finely but not very 

 densely appressed-silky on both faces ; cauline leaves an inch 

 long, erect or ascending, broad at the sessile base, but slenderly 

 acuminate, the almost caudate tips twisted : cymes rather com- 

 pact, of 6 to 12 heads ; involucres greenish and lightly woolly at 

 base, the outer and hardly scarious-tipped bracts oblong, obtuse, 

 the next series more elongated and with broad acutish tips, the 

 innermost series linear and acute, the scarious tips of all these 

 deep pink and slightly incised : male plant not seen. 



At 4,000 ft. in the Chilliwack Valley, 8 Aug., 1901, Mr. 

 Macoun ; No. 26,179. Only the pink involucres recall the com- 

 mon A. rosea, the long soft foliage loosely clothing the stolons, 

 and especially the slenderly and subcaudately acuminate stem^ 

 leaves mark it as very distinct. No. 26, 181 of the same collection, 

 from an altitude of 5,000 ft., I refer here, though it is a smaller 

 plant, and at a younger stage of development, and with involucres 

 that show but a tinge of pink. Again, No. 26,209, ^'so from 

 5,000 ft., and too young, has almost rose-red bracts. All these 

 plants show old foliage perfectly glabrous above, which is very 

 foreign to the character of A. rosea.
