Shrubs with alternate palmately veined and lobed leaves, the 

 flowers in few to many-flowered racemes. Calyx campanulate, 

 4-5-cleft with mostly equal marcescent lobes. Petals distinct as 

 many as the lobes of the calyx and alternate with them. Stamens

 of the calyx. Ovary 1-celled, closely adnate to the tube of the 

 calyx, with 2 parietal mostly many-ovuled placentae. Fruit a berry.

R. aureuui Pursh Fl. 164. A smooth shrub 4-8 feet high: leaves 

 3-lobed, often broader than long, the lobes usually divaricate, few-toothed

 row tube 6-8 lines long, about twice as long as the oblong merely spreading 

 lobes ; petals cuneiform, truncate and erose-dentate at the apex, little more 

 than a line long : berries yellow or black, 2-3 lines in diameter. On rocky 

 banks along streams, eastern Oregon and Washington to Missouri and 

 Arkansas. 



R. teiiuiflorum Lindl. Hort Trans, vii, 242. A slender shrub 6-12

 lobed, crenate at the apex, 1-3 inches in diameter: racemes usually about 

 9-flowered, leafy at base: bracts foliaceous, broadly lanceolate, 6-9 lines 

 long, usually longer than the pedicels; calyx-tube 7-8 lines long, by a line 

 in diameter, the unequal lobes about 3 lines long by less than a line broad : 

 petals about a line long, narrowly o long, narrowed below to a broad 

 claw : berries 2-3 lines in diameter.' Along streams, southern Oregon and 

 adjacent California.
