2. multiflfira, Thunb. (R. polydnthos, Roessig. R. 

 thyrsiflbra, Leroy. R. intermedia, Carr. R. Wichurae, 

 Koch). Fig. 3435. Deciduous shrub, with vigorous, 

 long, recurving or climbing branches: Ifts. usually 9, 

 obovate to oblong, acute or obtuse, serrate, pubescent, 

 %-lM in. long: fls. in many-fld. pyramidal corymbs, 

 usually white, %in. across or more; sepals ovate, 

 abruptly acuminate; styles glabrous: fr. small, globular. 

 June. Japan, China. B.M. 7119. G.F. 3:405 (adapted 

 in Fig. 3435); 4:535; 6:316, 317. A.G. 18:677. A.F. 

 6: 1003. Gn. 49, p. 368 (as R. microcarpa); 55, p. 432;

 Gng. 5: 120, 121. The typical form which is sometimes 

 distinguished as var. Thunbergiana, Thory, has small 

 single white fls. and is found in Japan and Korea. Var. 

 cathayensis, Rehd. & Wilson. Fls. pink, about 1J^ in. 

 across, in rather flat corymbs. China. This is the wild 

 single-fld. form from which the two following varieties 

 have been derived. Var. carnea, Thory (var. plena, 

 Regel. R. florida, Poir.). With double light pink fls. 

 B.M. 1059. B.R. 425. Var. platyphylla, Thory, with 

 larger Ivs. and larger double, deep pink fls. B.R. 1372. 

 This is known as SEVEX SISTERS ROSE. A form of this 

 with intense red and more numerous fls. is the well- 

 known "Crimson Rambler," one of the best climbing 

 roses (Fig. 3436). A.G. 16:233. Many hybrids have 

 originated in cult.; they usually show their parentage 

 by the pectinate stipules. A hybrid with R. rugosa is 

 R. Iwdra, Sieb., with single, rather small white fls. 

 W. R. 61. Of the same parentage is R. yedoensis, 

 Makino, with small pink fls. R. polyantha, Hort., not 

 Roessig, is a trade name for hybrids with R. chinensis.

 hybrid with General Jacqueminot. G.W. 7, p. 125. 

 Hybrids with R. setigera, R. gaUica, and R. Wichuraiana 

 have also been raised. 



3. Watsoniana, Crpin (R. multiflora var. Watson- 

 idna, Matsum.). Fig. 3437. Deciduous shrub, with 

 sarmentose or recurving branches: Ifts. 3-5, linear-lan- 

 ceolate, with entire wavy margin, pHbescent beneath, 1- 

 2% in. long: fls. in many-fld. pyramidal corymbs, J^in. 

 across or less, white or pink; style glabrous: fr. small.

June, July. R.B. 14, p. 183. G.F. 3:477 (adapted in 

 Fig. 3437). W.R. 16. A very curious rose of unknown 

 origin, supposed to have been intrp. from Japan, but 

 not known in a wild state. Not quite hardy North. 



4. setigera, Michx. PRAIRIE ROSE. Figs. 3438, 3439. 

 Shrub with prickly branches attaining 6 ft., with long 

 and slender recurving or climbing branches: Ifts. 3-5, 

 ovate to oblong-ovate, shortly acuminate, serrate, 

 tomentose beneath, 1-3 in. long: fls. in rather few-fld. 

 corymbs, deep rose, fading to whitish, about 2 in. 

 across, almost scentless ; pedicels and receptacle glandu- 

 lar-hispid; style glabrous: fr. globular, J^in. across. 

 June, July. From Ont. and Wis. to Texas and Fla.

 Var. tomentdsa, Gray (R. rubifdlia, R. Br.). Lvs. more 

 tomentose beneath : corymbs with more, but smaller fls. 

 A valuable hardy climbing rose. Several varieties 

 with double fls. are in cult.; some are probably hybrids 

 with R. arvensis, R. multiflora, R. Noisettiana, and other 

 species.
