Antennariae novae canadenses. 1(}3 



elongated and with hroad acutish tips, the innermost series linear and 

 acute, the scarious tips of all these deep pink and slightly incised: male 

 plant not seen. 



British Columbia: At 4000 ft. in the Chilli wack Valley, 8 Aug. 

 1901, Mr. Macoun; no. 26179. 



Only the pink involucres recall the common A. rosea, the long soft 

 foliage loosely clothing the stolons, and especially the slenderly and sub- 

 caudately acuminate stem leaves mark it as very distinct. No. 26,181 of 

 the same collection, from an altitude of 5000 ft., I refer here, though it 

 is a smaller plant, and at a younger stage of development, and with in- 

 volucres that show but a tinge of pink. Again, no. 26,209, also from 

 5000 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. 



4. Antennaria sedoides Greene in Ottawa Nat., XVIII (1904), p. 37. 

 Low, loosely matted, rather obviously suffrutescent. the short and 



slender stolons bearing a rosette of leaves at the end, these scarcely 

 V2 inch long, rather abruptly spatulate- contracted below a very broad 

 and short obtuse terminal part, both faces finely densely and permanently 

 silvery- woolly or satiny; flowering stems only 2 or 3 inches high, very 

 slender but firm, their lower leaves oblong-linear, the upper linear: heads 

 4 or 5, their involucres with ovate rather acute dull-white scarious tips. 



British Columbia: By roadsides at Banff, 28th May 1901, N. B. 

 Sanson. 



Only pistillate plants, and these much too young; not even yet in 

 flower. But the rosetted stolons, looking like those of some Sedum, are 

 very characteristic. 



5. Antennaria Sansonii Greene, 1. c, p. 37. 



Short leafy stolons and slender though firm stems closely tufted, the 

 latter 6 or 8 inches high; basal leaves small and very narrow, linear- 

 spatulate, acutish, Va to 3 / 4 inch long, densely, closely and very per- 

 manently silky-woolly, the cauline linear, acute or acuminate, erect: 

 cymes neither dense nor lax, of 8 or 10 heads of middle size; involucre 

 rather strongly woolly at base, each bract marked with a brown spot 

 at base of the long and conspicuous scarious but faintly pinkish tip. 

 only the innermost tips acutish, the others obtuse, all apt to be a little 

 incised. 



British Columbia: A rather neat and elegant firmly erect species, 

 obtained by Mr. H. B. Sanson on the slopes of Sulphur Mountain, ne.ir 

 Banff, 16th July 1901. 



It is somewhat related to A. acuminata, although distinct enough by 

 its compact habit, and permanently silvery foliage. Even the dead leaves 

 of a former year are not divested of their indument. The type is the 

 Geol. Survey no. 26857. 



6. Antennaria chlorantha Greene, 1. c, p. 38. 



Low, rather loosely tufted, 3 to 5 inches high, the short stolons not
