 hypanthium ; ovary beset with short-stalked or barely sessile glands ; style glabrous ; berry blue- 

 black, glaucous, sparingly glandular. 



Mountain streams and meadows, Transition and Canadian Zones; southern Oregon to southern California, 

 east to western Nevada. Type locality: not given, but probably near Placerville, California. May-June.

 long, red, pubescent ; sepals oblong, slightly longer than the hypanthium ; petals spatulate, about 

 half as long as the sepals ; style glabrous ; berry blue-black, with a bloom, slightly glandular.

Resembling R. sanguineum in general habit, but the young twigs, petioles and racemes more 

 or less pubescent and glandular. Leaves slightly or not at all tomentose beneath, more or less 

 puberulent and glandular on both surfaces, the upper surface often glabrate in age; racemes 

 spreading or drooping ; pedicels 5-10 mm. long, usually longer than the bracts ; hypanthium 

 nearly cylindrical, 3-5 mm. long, rose-colored or rarely white, pubescent and slightly glandular ; 

 sepals rose-colored, a little longer than the hypanthium; ovary with stalked glands; style gla- 

 brous ; berry bluish with a bloom, or sometimes black.
