INDIAN MILK VETCH 



Astragalus aboriginorum. Pea Family 



Stems: finely glabrate, erect, branched. Leaves: leaflets linear, ob- 

 tuse; stipules ovate, acute, foliaceous. Flowers: white, tinged with 

 mauve in loose racemes; peduncles longer than the leaves; calyx black- 

 ish-pubescent, its teeth subulate. Fruit: pods semi-elliptic. 



One of the least attractive of the Vetches. It has a long 

 yellow root which is collected in the spring by the Stony 

 and Cree Indians as an article of food. The leaves are 

 whitish and rather silky, and the flowers are chiefly notice- 

 able by reason of their dark-hued hairy calyx. 



Astragalus tenellus, or Loose-flowered Milk Vetch, has 

 ascending stems and thin oblong pale green leaflets, which 

 are blunt at the apex and narrowed at the base. The flow- 

 ers are yellowish-white, sometimes tinged with pink, and 

 grow in loose spike-like racemes. The pod is stalked, 

 papery and pointed at both ends. 



LENTIL VETCH 



Phaca americana. Pea Family 



Stems: erect, nearly simple, tall, leafy, subglabrous. Leaves: leaf- 

 lets seven-to-nine paired, ovate, and elliptic-oblong; peduncles equal- 

 ling the leaves. Flowers: white, in a loose raceme. Fruit: pods ob- 

 long, acute at each end, black-hairy. 



A handsome plant, growing-one to two feet high, with 

 many leaves, and big white-flipwered heads. It has no ten- 

 drils, but grows very stiffly; with thick upright stalks.
