leaflet elliptic or oblong, or in the uppermost reduced pair lanceo- 

 late, 1-3 cm. long, the lateral ones oblong or lanceolate, about 

 half as long ; plant usually polygamo-dioecious ; inflorescence of 

 the essentially pistillate plant dense-corymbiform, that of the some- 

 what smaller essentially staminate plant subcapitate ; corolla fun- 

 nelform, 4-5 mm. long; limb 2.5-3 mm - wide; fruit glabrous, 

 nearly 5 mm. long and 2 mm. wide. 



This species has the pubescence of the preceding, but differs in 

 the smaller stature, the smaller flowers, fewer and smaller leaves, 

 glabrous fruit and a stronger tendency to be polygamo-dioecious. 

 It grows in the mountains of Utah, at an altitude of 2,000-3,000 m.
