SOME CANADIAN ANTENNARIAS.— II. 



By Edw. L. GREENfe. 

 Continuing the study of the Chilliwack Valley material col- 

 lected by Mr. James M. Macoun in igoi, it becomes more and 

 more evident that the genus Antennaria is strongly developed in 

 British Columbia ; so much so, that for the western slope of 

 North America it may be said to have there its centre of distribu- 

 tion. And this interesting forecast is further warranted by the 

 fact that, from the vicinity of Banff, Mr. N. B. Sanson has ob- 

 tained, among other species of the genus, at least two more that 

 are hitherto undescribed. 



In attempting to describe the new species, I cah not but 

 regret the absence of specimens of the staminate, or male plants; 

 for these have their own characters that help to establish the 

 validity of species; and I would beg of future collectors of British 

 Columbian Antennarias, that they make special search for male 

 plants. They are, it is well recognized, less common than the 

 pistillate ; but they should be sought, diligently, at every oppor- 

 tunity. 



A. SEDOIDES. Low, loosely matted, rather obviously suffru- 

 tescent, the short and slender stolons bearing a rosette of leaves 

 at the end, these scarcely ^ 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. 



By roadsides at Banff, B.C., 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 

 Sidum, are very characteristic. 



A. Sansonii. 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, ^ to ^ inch 

 long, densely, closely and very permanently silky-woolly, the
