orbicular. Stigmas two, capitate; ovary and immature fruit 

 clothed with stipitate glands. 



This species belongs in the group of which R. nevadense 

 Kellogg is the type. It differs from that species in the inflor- 

 escence and the shape of the floral organs.

 County, California, not far from Twin Lakes, July 9, 1901, and 

 named in honor of Mr, Carlos T. Hittell, one of the party on a

This species is related to Ribes nevadense Kellog-g from 

 which it differs in the glaucous color of its foliage, the racemes 

 erect in fruit, and the shape of the floral organs. It was col- 

 lected by the author on Mount Shasta, August 13, 1893. No
