Valeriana trachycarpa sp. nov. 



Perennial with a thick fleshy root ; stem glabrous or nearly 

 so, 5-7 dm. high; basal leaves oblanceolate or spatulate, 7-18 

 cm. long, finely puberulent, especially on the margins and veins ; 

 entire or with a few linear lobes, thick ; stem-leaves 1-2 pairs, pin- 

 natifid with linear lobes ; inflorescence large and branched ; corolla 

 of the staminate plant 2.5-3 mm - wide; that of the essentially pis- 

 tillate plant about 1.5 mm. wide; fruit broadly ovate, not hairy, 

 but strongly rugose. 



This is closely related to V. edulis and V. purpurascens, but 

 the former has pubescent ovary and fruit and narrower bracts, and 

 the latter has narrower fruit, narrower leaves, more slender inflo- 

 rescence and smaller staminate flowers, only 2 mm. wide ; V. 

 trachycarpa grows at an altitude of 2500-3000 m.
