NEW PLANTS FROM ALBERTA. 



By Edw. L. Greene. 



Berberis brevipes. Allied to B. nana but every way smaller, 

 the foliag-e of a deeper green and merely g-laucescent rather than 

 g-laucous ; leaves with very short petiole, not longer than the inter- 

 nodes of the rachis ; leaflets usually seven, rather broadly elliptic- 

 oblong, I to I y^ inches long, sharply and closely spinulose-serrate, 

 very acute, conspicuously though minutely reticulate, in texture 

 comparatively thin ; racemes short and few-flowered, but in fruit 

 surpassing the petioles ; berries small, subglobose, blue and very 

 glaucous. 



Collected at Crow's Nest Pass, Rocky Mts., August, 1897, by 

 Prof. John Macoun; No. 18,080 of the Canadian Geological Survey 

 Collection. It is next of kin to the more southerly B. naiia, 

 Greene, which so long passed, by mistake, under the name of B. 

 repens; but it is wholly distinct by several characters, among the 

 best of which is the short-stalked foliage. In B. nana the petioles 

 are so long as to surpass even the long fruiting racemes. 



Stfllaria subvestit.v. Numerous suberect stems densely 

 tufted, slender though firm, 5 to 10 inches high, very leafy below 

 the middle, the dichotomous cyme notably narrow and strict ; 

 leaves linear-acuminate, ^ inch long, i-nerved, erect, sub- 

 tomentose beneath, otherwise more or less pilose-pubescent, the 

 stem also pilose, the peduncle and pedicels less so ; bracts of the 

 cyme ovate or ovate-lanceolate, acute, scarious, often villous- 

 ciliate; sepals oval, obtuse or acutish, scarious-margined, i-nerved 

 and the nerve often pilose; petals little exceeding the calyx ; cap- 

 sule not seen. 



Obtained at Devil's Head Lake and Banff", National Park, 

 July, 1891, by Prof. John Macoun ; the specimens distributed for 

 S. longipes var. ; but the species is of diff'erent habit, and is well 

 marked by the strong pubescence, the strict and narrow cyme, etc.
