3-4. Fruit a berry, crowned with the remains of the flower, 

 1-celled, usually many-seeded. Seeds anatropous, the raphe at 

 length distinct from the gelatinous testa : the inner integument 

 somewhat crustaceous, adhering firmly to the fleshy albumen. 

 Embryo minute excentric. 



1 RIBES Juss. Gen. 28 L. L. Gen. n. 281. 



Shrubs with alternate palmately veined and lobed leaves, the 

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

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

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

 as many as petals, inserted alternately with them into the throat 

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

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



1 SIPHOCALYX Berlandier Mem. Soc. Gnev. iii, t. 2 as 

 genus. Stems neither prickly nor thorny: leaves convolute in 

 the bud: racemes many-flowered: bracts foliaceous : flowers yellow; 

 calyx long and tubular : berries smooth. 



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

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

 at the apex, ciliate when young, otherwise very glabrous : racemes 10-30- 

 flowered, leafy at base; bracts lanceolate, more or less acuminate, 2-6 lines 

 long or more, about equalling the pedicels: calyx yellow, tubular, the nar- 

 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. tenniflorum Lindl. Hort Trans, vii, 242. A slender shrub 

 feet high, glabrous or the young branches and leaves pubescent with 

 spreading hairs: leaves round-cordate, 3-ipbed, the lobes often again 2-3- 

 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. 



2 EIBESIA Berlandier (CURRANT). Stems neither prickly nor 

 spiny : leaves plicate in the bud: racemes several-flowered : calyx 

 campanulate or cylindrical: ovules numerous, in 2 or more rows. 



* Calyx produced into a campanulate or cylindrical tube: fruit 

 and foliage more or less glandular : bracts conspicuous : stamens not 

 produced beyond the petals. 



-- Flowers dull white or light-colored; racemes corymb-like and few- 

 flowered. 



R. viscosissimiiiii Pursh Fl. 163. A shrub 3-5 feet high with reddish 

 shredy bark and stiffish branches: young branches, leaves and inflores- 

 cence viscid-pubescent: leaves round -cordate, shallowly 3-lobed, incisely 

 crenate, 1-2 inches in diameter: racemes short; bracts spatulate, 6-8 lines 

 ong, about equalling the glandular pedicels; calyx-tube cylindrical, 5-6
