branches shining, glabrous, of the older flaky and deciduous : leaves 

 2 -4 in. broad, very thin, not rugulose, bright green and glabrous above, 

 paler beneath with a sparse tomentulose pubescence ; stipular base of 

 petiole clothed with very long coarse hairs each of which is sparsely 

 pilose : racemes short and dense (1 in. long), pendulous on slender 

 petioles of 2 in. or more : A. small, rose-red : calyx-tube urceolate, 

 broadest just above the ovary, only Ifg lines long, the spreading segments 

 as long or longer : berry small, globose, black, densely glaucous ; pulp 

 soft, very sweet. — At middle elevations in the Sierra Nevada, in open 

 groves of Sequoia, from Kern Co., Palmer & Wright (n. 101), and the 

 Calaveras Big Trees, Greene, to Placer Co. A most distinct species, of 

 peculiar habitat ; the foliage thinner and more nearly glabrous than 

 that of E. glalinosuin, which is its analogue of the Coast Range. In all 

 three of the last preceding the bark of the stem and older branches is 

 close, smooth, dark brown and white-dotted, like that of young birches. 

 In the present species it is flaky and deciduous. Doubtless the R. Woljii 

 of regions east of the Sierra, in Nevada and Colorado, is another member 

 of this group of American Black Currants.

9. R. lacustre, Poir. Suppl. ii. 856 (1811), var. moUe, Gray, Bot. 



Calif, i. 206. Shrub small and depressed, the spreading branches 3^^— 2 

 ft. long, bristly or naked, armed with short triple or multiple thorns 

 under the leaf-fascicles : leaves }{ — 1 in. broad, deeply 5-parted, the 

 lobes incisely toothed and cleft, pubescent : racemes 3 — 9-flowered : fl. 

 greenish- white ; calyx saucer-shaped, }4- i^- broad, its short lobes 

 rounded ; petals small ; stamens very short : berry globose, red, ^{ in. 

 thick, more or less glandular-hispid ; pulp juicy, acidulous. — At rather 

 high altitudes of the Sierra, in rocky shades ; quite intermediate between 

 Currant and Gooseberry. 



10. R, oxyacaiithoides, Linn. Sp. PI. i. 201 (1753). Mostly glabrous, 

 2 — 4 ft. high ; thorns small, single or triple : leaves roundish, deeply 

 5-lobed ; lobes incised and coarsely toothed : peduncles mostly shorter 

 than the pedicels of the 2 or 3 flowers : fl. greenish-white, 3 — 4 lines long ; 

 calyx-lobes oblong, equalling the campauulate tnbe, little exceeding the 

 cuneate-obovate petals, about equalling the stamens ; style cleft, villous 

 below, longer than the stamens : berry of middle size, glabrous, black, 

 pleasant. — This widely distributed species occurs within our limits only 

 toward the higher parts of the Sierra, and chiefly on the eastward slope.
