EIGHT NEW SPECIES OF NORTH AMERICAN 

 PLANTS.* 



BY CHARLES LOUIS POLLARD. 



Lupinus psoraleoides n. sp. 



Perennial, 1-1| dm. high, subacaulescent, with a multicipital caudex 

 and slender woody root; whole plant densely villous with long white 

 hairs; leaves long-petioled, the blades 5-7-foliolate; leaflets oblanceolate, 

 somewhat acute at the apex, 2-3 cm. long; spike very densely flowered, 

 almost sessile, scarcely surpassing the foliage; flowers violet purple, 1 

 cm. long, subtended by narrowly linear scarious bracts; calyx one-half 

 the length of the corolla, markedly bilabiate, the teeth acute; standard 

 suberect, shorter than the keel; legume oblong, \\ cm. long, tipped 

 with the slender persistent style; seeds few, apparently nearly orbicular. 



Type in the U. S. National Herbarium, No. 201,582, collected in open 

 gravelly soil at Gunnison, Colorado, by Elam, Bartholomew, August 30, 

 1899 (No. 2(580). In aspect the plant suggests certain species of Psoralea; 

 its marked peculiarities are the slender nearly sessile spike, the small 

 standard and the long villous pubescence. 



Viola amorphophylla n. sp. 



Plant acquiescent, about 1 dm. high, from a stout, vertical rootstock, 

 absolutely glabrous throughout and semisucculent; blades of the leaves 

 elliptical or oblong-elliptical, the margins entire or sometimes obscurely 

 crenate near the very obtuse apex, rarely with a small lobe or incision 

 near the rounded or slightly tapering base; petioles narrowly margined, 

 equalling: the blades or shorter; stipules scarious, elongated-linear; 

 scapes surpassing the foliage; flower purple, about 2 cm. broad; sepals
