stamens and style equaling the sepals: fr. dark red, 

 smooth. S. Eu. B.M. 2368. L.B.C. 14:1331. R.F.G. 

 23:138a. L.I. 31. 



15. vulgare, Lam. (R. hortense, Hedl. R. satwum, 

 Syme. R. rubrum of many authors, not Linn.). RED 

 or GARDEN CURRANTS. Fig. 3404. Upright shrub, to 5 

 ft.: young growth pubescent and slightly glandular: Ivs. 

 thin, cordate or subcordate, 3-5-lobed, with short-ovate, 

 acutish, serrate lobes, pubescent at least on the veins 

 beneath, 1^-2 y^ in. broad: racemes drooping, many- 

 fld., glabrous or nearly so; pedicels filiform, much 

 longer than the ovate bracts; calyx-tube saucer-shaped, 

 green or slightly purple inside between the stamens 

 and the style with an elevated slightly 5-angled ring; 

 anthers with a broad connective separating the cells: 

 fr. red, whitish, or striped, juicy, the dried remnants 

 of the fl. 5-angled at the base. W. Eu. S.E.B. 4:520. 

 B.B. (ed. 2) 2:237. Var. macrocarpum, Jancz. (R. 

 acerifblium, Hort.). Of irregular habit on account of 

 the lateral branchlets being partly without buds: Ivs. 

 Jarge, deeply cordate, 3-lobed, with a very large middle 

 lobe: racemes without Ivs. at the base: fr. large, always 

 red. To this variety belong most of the large-fruited 

 "cherry currants," tenderer than the typical form. R. 

 vulgare is the parent of most of the cult, currants. Some 

 of the hardier and smaller-fruited varieties are proba- 

 bly crosses with the hardier R. rubrum; they have been 

 named R. Houghtonianum, Jancz. Other hybrids of 

 this species are R. Goudulnii, Jancz. (R. vulgare x R. 

 petrseum). R. Koehneanum, Jancz. (R. vulgare x R. 

 multiflorum) and R. futurum, Jancz. (R. vulgare x R. 

 Warscewiczii) . 



16. riibrum, Linn. (R. Schlechtendalii, Lange. R. 

 sylvestre, Syme. R. scdndicum, Hedl.). NORTHERN 

 RED CURRANT. Shrub, to 6 ft. : young growth usually 

 glabrous: Ivs. truncate, rarely subcordate, 3-5-lobed, 

 usually nearly glabrous, to 5 in. across: racemes usually 

 spreading; pedicels short; bracts very small; fls. green- 

 ish or brownish; calyx-tube saucer-shaped, without 

 prominent ring inside; anthers with contiguous cells: 

 fr. usually red, juicy, the dried remnants of the fl. 

 circular at the base. Cent, and N. Eu. N. Asia. S.E.B. 

 4:522. Var. pubescens, Swartz. Young shoots slightly 

 pubescent: Ivs. pubescent beneath: racemes shorter; 

 fls. brown or pinkish :fr. small. N. Eu. Var. glabellum, 

 Trautv. & Mey. Young branchlets and Ivs. glabrous: 

 fls. larger, pink or brownish red: fr. larger. N. 

 Asia. R. rubrum is rare in cult, outside of the gar- 

 dens of N. Eu. where forms with red, pink or whitish 

 frs. are grown. Besides R. Houghtonianum, mentioned 

 under the preceding species, two other crosses of R. 

 rubrum are known: R. pdllidum, Otto. & Dietr. (R. 

 rubrum x R. petrseum), and R. holosericeum, Otto & 

 Dietr. (R. rubrum x R. petrseum var. caucasicum). 



17. fasciculatum, Sieb. & Zucc. (R. japonicum, Carr., 

 not Maxim. R. alpinum japonicum, Nichols.). Shrub, 

 to 4 ft., with upright or ascending branches: Ivs. sub- 

 chartaceous, truncate to cordate, 3-5-lobed, with 

 obtusish lobes, glabrous or slightly pubescent, to 5 in. 

 across: fls. dioecious, small, greenish; male fls. in 4-9- 

 fld. clusters, pistillate fls. 2-4; calyx-tube cup-shaped; 

 anthers subsessile: fr. subglobose, scarlet, glabrous, 

 Hin. across, insipid. April, May; fr. in Sept., Oct. 

 Japan.- Var. chinense, Maxim. (R. Billidrdii, Carr.). 

 Lvs. larger, persisting until the beginning of the winter, 

 lobes more acutish, pubescent beneath like the petioles 

 and young branchlets. N.China. S.T.S. 1:38. M.D.G. 

 1899:571. Handsome shrub chiefly valued for its 

 late persisting foliage and the bright scarlet berries 

 remaining on the branches during the whole winter. 



18. alpinum, Linn. (R. opidifqlium, Hort.). ALPINE 

 CURRANT. Dense shrub, attaining 8 ft. and as much or 

 more through, with upright sts. and spreading branches, 

 nearly glabrous: Ivs. truncate or subcordate, 3-lobed, 

 rarely 5-lobed, with obtuse or acutish dentate lobes, 



1-2 in. across: fls. dioecious, small, greenish, in upright 

 racemes, the male 1-2 Yi, the female M-1H in. long; 

 the calyx-tube nearly flat; sepals ovate, petals minute; 

 filaments very short: fr. subglobose, scarlet, glabrous, 

 insipid. Eu. L.B.C. 15:1486. S.E.B. 4:519. R.F.G. 

 23:135. Several named varieties of little importance 

 are known; the best known are : Var. pftmilum, Lindl. (var. 

 hiimile, A. Braun). Dwarf form with smaller Ivs. Var. 

 laciniatum, Kirchn. Lvs. more deeply lobed and incisely 

 toothed. Var. aureum, Bean (var. pumilum aureum, 

 Pynaert, var. foliis-aureis, Hort.). Dwarf form with 

 yellowish foliage. R.B. 4:233. The pistillate fruiting 

 form is sometimes distinguished as var. bacciferum, 

 Loud., and the staminate sterile form as var. sterile, 

 Loud. The Alpine currant is a desirable shrub of 

 dense habit, unfolding very early its bright green foli- 

 age, adorned in summer and autumn with bright scar- 

 let berries; it is one of the best shrubs to plant as under- 

 growth and in shady places. 



19. diacantha, Pall. (R. saxdtile, Pall.). Upright 

 shrub, to 6 ft. : branches glabrous, slender, upright, with 

 paired small slender prickles at the nodes or unarmed: 

 Ivs. oval or cuneate-obovate, 3-lobed with sparingly 

 dentate, obtusish lobes, glabrous, lustrous, with obsolete 

 veins, %-!% in. long; petioles about ^in. long: fls. 

 dioecious, small, greenish, in upright racemes, the stami- 

 nate about 1)4 in. long, the pistillate J^-Min. long; 

 calyx-tube flat; sepals oval, petals minute: fr. subglobose 

 or somewhat ovoid, scarlet. N. Asia. Like the preced- 

 ing species desirable for its bright green more lustrous 

 foliage and for its scarlet fr., but habit upright, not 

 spreading. 



20. lacustre, Poir. SWAMP BLACK CURRANT, or 

 SWAMP GOOSEBERRY. Shrub with slender weak sts., 

 usually densely bristly; prickles slender, often clustered:

 fld. ; fls. greenish or purplish; calyx-tube saucer-shaped; 

 sepals spreading, broad and short; stamens very short: 

 fr. subglobose, purple-black, with gland-tipped bristles.

 Colo., and Calif. L.B.C. 9:884. B.M. 6492.

 Shrub, to 8 ft., upright or ascending: branches reddish 

 brown, with stout brown prickles 3-i~Min. long, with- 

 out bristles: Ivs. suborbicular, thin, 3-5-lobed, with

 gooseberries. (X 1 A)
