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. 281. L. Gen. n. 281. 
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 
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 placente. Fruit a berry. 
§ 1 Srenocatyx -Berlandier Mem. Soc. Gnev. iii, t. 2 as 
genus. Stems‘neither prickly nor thorny: leaves conyolute in 
the bud: racemes many-flowered: bracts foliaceous: flowers yellow; 
calyx long and tubular: berries smooth. 
R. aureum 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 
roan along streams, eastern Oregon and Washington to Missouri and 
Arkansas. 
R. tenuiflorum Lindl. Hort Trans. vii, 242. A slender shrub 6-12 
feet high, glabrous or the young branches and leaves pubescent with 
spreading hairs: leaves round-cordate, 3-lobed, 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 !anceolate, 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 Rreesta Berlandier (Currant). Stems neither prickly ner 
spiny: leavés 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 nat 
produced beyond the petals. 
+ Flowers dull white or light-colored; racemes corymb-like and few-

R. viscosissimum 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 
long, about equalling the glandular pedicels; calyx-tube cylindrical, 5-6
