Rosa rugosa, Thunb. (R. ferox, Lawr. R. Regeliana, Andre & Lind. R. coruscans, Waitz). Figs. 3446-3448.Upright shrub, attaining 6 ft., with stout sts. densely beset with prickles and bristles: lfts. 5-9, oval to obovate-oval, rugose, shining and dark green above, glau- cescent and pubescent beneath, thick and firm, 3/4 - 2 in. long; petioles tomentose and bristly; stipules dilated: fls. solitary or few, purple or white, 2 1/2 - 3 1/2 in. across: bracts large; pedicels prickly; receptacle smooth: fr. depressed-globose, brick-red, to 1 in. across. May- Sept. N. China, Korea, Japan. S.Z. 1:28. B.R. 420. Gt. 30:1049; 42, p. 537. G.C. II. 14:372. Gn. 46, p. 324; 52:384; 55, p. 434. I.H. 18:47. Gng. 1:7; 5:339. A.G. 13:342, 344; 18:567. C.L.A. 2:76: 7:624. F.E. 18:6. J.H. III. 45:159.—Forms of typical R. rugosa, which is sometimes distinguished as var. Thunbergiana, C. A. Mey., are the following: Var. alba, Rehd. (var. albiflora, Koidzumi), with white fls. Gn. 9:452. G. 8:261. Var. albo-plena, Rehd., with double white fls. Var. rosea, Hort., with pink fls. Var. rubra, Hort., with purple fls. Var. rubro-plena, Rehd., with double purple fls. Gt. 24:846. Geographical varieties, not of garden origin, are the following two: Var. amissoniana, C. A. Mey. (R. pubescens, Baker, not Roxbg.). Bristles almost entirely absent on the branches: lfts. narrower and smaller, less rugose. A double- fld. form of this variety is sometimes cult, in Cent. China, but apparently not yet intro. into western gardens. Var. kamschatica, Regel (R. kamschatica, Vent.). With slenderer less densely armed branches, thinner less rugose lvs. and smaller fls. and frs. B.M. 3149. B.R. 419.—ft. rugosa is one of the most ornamental and at the same time hardiest of the single roses, valuable for shrubberies; it is very handsome on account of its dark green shining foliage, large fls. appearing during the whole summer, bright red conspicuous frs., and its beautiful orange and scarlet fall coloring. It is also attractive in winter by reason of its stout, densely armed sts. Large numbers of hybrids have been raised. By crossing with double-fld. garden roses, R. rugosa has given rise to a new race of hybrid roses remarkable for their hardiness and long blooming season; one of the host known is Mme. Georges Bruant (Fig. 3449), with double white fls., a cross of R. rugosa and the Tea rose Sombreuil. Another cross with a form of R. chinensis is R. calocarpa, Willmott (R. rugosa var. calocarpa, Bruant), with single rose-colored fls. and handsome fr. produced very abundantly. Gn. 46, p. 548; 52, p. 384. R.H. 1895, pp. 446, 447. I.H. 42, p. 15. W!R. 60. Remarkable for its large frs. and large fls. is R. micru- gdsa, Henkel (R. rugosa x R. microphylla. R. Vilmorinii, Bean). Upright, very spiny shrub: lfts. 7-11, small, pubescent: fls. pink, 3-4 in. across: fr. depressed- globose, about 1 3/4 in. across, prickly, orange-red. Gt. 59:1581. R.H. 1905:144. It is of vigorous growth and htirdy and will probably make a good hedge plant. Hybrids are also known with R. multiflora (see R. Iwara under No. 2), with R. Wichuraiana (see R. Jacksonii under No. 3), with R. cinnamomea, with R. spinosissima, with A. Carolina, a pretty rose with purplish red fls. (W.R. 65), with R. blanda=R. warleyensis. Willmott, a handsome rose with pink fls. and 5-7 small lfts. (W.R. 59), with R. palustris=R. Spaethiana. with large purple corymbose fls. (Gt. 51:1504, 3), and there are probably others.
