Throughout Oregon ! abundant in rocky situations along streams. — The 

 most ornamental species of the genus, bearing a profusion of deep rose-colored 

 flowers; now common in cultivation. " Berries insipid, covered with a dense 

 bloom." {Nutt.) 



26. jR. malvaceum (Smith) : young branches and petioles villous with a 

 viscid pubescence and glandular; leaves cordate, 3-5-lobed, doubly serrate, 

 very rugose and hispidly scabrous above, veiny and villous-tomentose be- 

 neath ; racemes scarcely longer than the leaves; flowers nearly sessile, 

 crowded; bracts ovate, sometimes incised; calyx tubular; the segments 

 ovate, shorter than the tube, spreading; petals very short, obovate-orbicular ; 

 style minutely 2-cleft at the summit; fruit ovoid, hairy. — Smith, in Rees,

California, TkZfflzies/ Douglas! Nuttall! — Avery distinct species. The 

 flowers are apparently not so brightly colored as in R. sanguineum. The 

 middle lobe of the leaves is ordinarily longer than the lateral ones. — The de- 

 scription of R. tubulosum of Eschscholtz accords pretty well with this species, 

 except that the petals are said to be oblong and longer than the calyx- 

 segments. 



§ 4. Stems neither prickly nor spiny : leaves convolute in vernation: racemes 

 many-floivered : bracts foliaceous : calyx long and tuhular {bright yellow): 

 berries unarmed. — Siphocalyx {Symphocaly.r, Berlandier), Endl. (Chry- 

 sobotrya, Spach.) 



27. R. aureum (Pursh) : glabrous; leaves 3-lobed, ciliate when young; 

 the lobes divaricate, incisely few-toothed ; calyx tubular, long and slender; 

 the segments spreading, much shorter than the tube, about twice the length of 

 the truncate eroselv denticulate petals; fruit glabrous. — Pursh! fl. 1. p). 164 ;

 longer than the spatulate nearly entire petals ; fruit glabrous. — Lindl. ! in

With the preceding; also in N. California, Douglas! April-May. — 

 Flowers much smaller than those of R. aureum: the fruit also smaller, glo- 

 bose. — " The fruit is the size of the Red Currant, with a thick skin and a 

 dense mucUaginous pulp, of an agreeable flavor, but possessing little acidity.
