RiBEs. GROSSULACE^E. 647 



Leavenworth ! April. — A quite distinct species with slender branches and 

 verv small leaves. We liave drawn our description from Dr. Leaven- 

 wort ii's plant, which we believe to be the same with that in the herbarium 

 of Michaux. 



8. R. rotundifolium (Miclix.) : sfoiiis not prickly; subaxillary spines short, 

 usually solitary ; leaves roiuulish, 5-lobct(l, nearly shibrous, .sliininn; above; 

 the lobes short and obtuse, inci.scly toothed; peduncles slender, l-2-fl(nvcred, 

 glabrous; calyx cvHudrical and narrow, glabrous, as well as the ovary ; the 

 segments liuoar-oblonii, a little s]ireadiuir, twice tin- b-nglh r)f the tube ; fila- 

 ments exseried, glabrous, twice or tlirice the length of the broadly-spatulate 

 ungiiiculate petals; anthers roundish ; style detply 2-parted, as long as the 



'stamens, hairy below; fruit small, smooth. — Michx. ! jl. 1. /;. 110. R. tri-

In mountainous and rocky places, Massachusetts! New York ! to the 

 mountains of N. Carolina! and west to Missouri, and, according to Douglas, 

 beyond the Rocky Mountains. .Tune. — Shrub 3-4 feet high, with sjjreading 

 recurved branches ; the spines occasionally absent. Leaves small, truncate 

 or slightly cordate, or often a little cuneiform at the base ; the lower surface, 

 as well as the short petioles, often somewhat pubescent. Fruit about the size 

 of the Black Currant, at length purple, delicious. 



9. JR. divaricatum (Dougl.) : branches divaricate, bristly or naked ; sub- 

 axillary spines 1-3, very stout, at length deflexed ; leaves roundish, 3-6- 

 lobed, '^incisely toothed, often pubescent ; peduncles 2-3-9owered, slender, 

 nodding ; calyx-tube funnel-shaped, about half the length of the oblong re- 

 flexed segments; stamens exserted, more than twice the length of the deltoid 

 unguiculate petals ; style as long as tlie stamens, deeply 2-cleft, hairy below ; 

 fruit smooth. — Dougl..' in hort. trans, l.p. 515; LincU..' hot. reg. t. 1359;

Banks of streams, Oregon, Douglas! Dr. Seoul cr ! Nuttall! also in Cali- 

 fornia ! — Resembles R. rotundifolium, Michx. but has larger and brownish- 

 purjde flowers of a somewhat ditlerent shape, and remarkably large and 

 stout spines, although these arc said to be occasionally wanting. The fruit 

 is said to be black, about one-third of an inch in diameter, and pleasant to the 

 taste. A specimen in Douglas's Californian Collection, probably the R. tri- 

 florum mentioned iu the Sirpplement to the Botany of Beechey's Voyage, p. 

 346, perhaps belongs rather tp the present species. 



10. R. xillosum (Nutt. ! mss.) : "stems smooth; subaxillary spines 3, 

 stout, unequal ; leaves^ 3-cleft (small) with obsolete lateral lobes, incisely 

 and unequally too!,hed,''cancscently tomentose beneath; peduncles mostly 2- 

 flowered; bracts roundish-ovate; calyx (brown, hairy) cleft nearly to the 

 base ; petals short, obtuse ; stamens somewhat exserted ; anthers short and 

 roundish ; style 2-cleft ; ovary smooth. 



" St. Barbara, California ; common near the village on the plain." Nut- 

 tall. Wc have only seen a very imperfect sijccimen of this species, which 



appears distinct, butis perhaps too near R. divaricatum. 



11. R. irrisuum (Dougl.): subaxillary spines 3; leaves cordate, about 

 5-lobed, toothed, ciliate, hairy on bodi sides, veiny ; peduncles 3-flowered, 

 glandularly hairy ; calyx campanulate; the segments hnear, ecjual to the 

 tube; fruit smooth. Dougl. in hort. trans. 7. p. 516,- Hook. I. c. ; Lindl.
