 States and Chihuahua. 



Canbya aurea. Dwarf, few-many-stemmed, with fleshy linear 

 glabrous or sparingly pubescent leaves (1 to 3 lines long), clustered at 

 the base, and naked scape-like peduncles ^ to 1 inch long: flowers 

 bright orange, the petals (Ig lines long) deciduous. — On the sage- 

 brush plains of eastern Oregon ; Thomas Howell, June, 1885, with the 

 habit of C Candida, and its peculiar stigmas, varying from it in the color 

 and deciduous character of the petals. Mature fruit was not found.

 above, glabrous and glaucous, but the base of the stem and the radical 

 leaves villous with spreading hairs : radical leaves oblanceolate, toothed 

 or pinnatifid, an inch or two long, the cauline entire, lanceolate, sagit- 

 tate and clasping : flowers scattered, ascending on short pedicels ; calyx 

 2 or 3 lines long; petals narrowly linear, long-exserted : pods ascend- 

 ing, stipitate, slender, an inch long, tipped with a slender style. — Most 

 nearly resembling T. brachycarpum. At Camp Polk and in Harney 

 Valley, eastern Oregon ; Thomas Howell, June, 1885. 



PoLYGALA acicularis. Perennial, with stout branching caudex 

 and numerous slender lax ascending somewhat fasciculately branched 

 stems about a foot high, puberulent: leaves very numerous, alternate, 

 sessile, narrowly linear, acuminate or acute, carinate, slightly puberu- 

 lent or glabrous, 3 to 6 lines long : racemes sessile, short, few-flowered ;
