 not Linn. Grossuldria hirteUa, Spach). Fig. 3405. 

 Shrub, to 4 ft., with slender branches, usually unarmed, 

 sometimes with subulate small spines, only at the base

3406. Ribes Cynosbati. ( X &) 



Houghton, and Smith are thought to belong, while Pale 

 Red appears to be of pure R. hirtellum parentage.
