493; 77, p. 511; 79, p. 113 (as R. moschata). G. 6:529; 

 30:419. G.C. III. 36:152, 153. W.R. 10. A hand- 

 some strong-growing rose, but more tender than the 

 real musk rose with which it has been much confused. 

 6. moschata, Mill. (R. rusdnonensis, Desv.). MUSK 

 ROSE. Shrub, with arching or sarmentose branches, 



3437. Rosa Watsoniana (X 1 A). No. 3. 



glabrous: prickles rather small and slender, straight or 

 slightly hooked: Ifts. 5-7, elliptic-ovate to oblong-ovate, 

 acute or acuminate serrulate, glabrous above, hairy on 

 the midrib beneath, otherwise glabrous or nearly so, 

 1-2 in. long; petioles and rachis nearly glabrous, 

 usually prickly: fls. white, 1^-2 in. across, fragrant 

 with the odor of musk, in usually 7-fld. corymbs; sepals 

 lanceolate, much longer than the receptacle, lobed, 

 deciduous; pedicels slender, slightly pubescent and 

 glandular; styles pubescent: fr. ovate, small. June, 

 July. S. Eu., N. Afr. W.R. 9. Var. nastarana, 

 Christ (R. Pissdrdii, Carr.). A more robust form: 

 prickles slightly curved: Ifts. nearly glabrous beneath: 

 fls. more numerous, over 2 in. across. Persia. R.H. 

 1880, pp. 314, 315. W.R. 10. Hardier than the type. 

 Var. abyssinica, Rehd. (R. abyssinica, Lindl.). More 

 prickly and glandular: Ifts. smaller, scarcely acuminate: 

 infl. more compact; sepals with smaller lobes or without. 

 Abyssinia. Tender; cult, in Calif. The musk rose of 

 the older writers, known since the 16th century, seems 

 to have at present almost disappeared from cult.; 

 the plant generally cult, under this name is R. 

 Brunonii, which is superior as a garden plant, 

 though it is somewhat tenderer. Several hybrids 

 are known; the most important is R. Noisettia.no,, a 

 hybrid with R. chinensis (see No. 13). A hybrid 

 with R. gallica is R. Dupdntii, Desegl. (R. moschata 

 var. nivea, Lindl.), which differs chiefly in its broader 

 and fewer Ifts., the glandular pedicels, the larger 

 fls. with shorter styles and in the presence of 

 bristles on the st. B.R. 861. Gn. 67:254; 77, p. 510. 

 W.R. 13. R. moschata densa, Vilm., belongs probably 

 to R. Gentiliana (see suppl. list). 



7. Helenae, Rehd. & Wilson. Sarmentose shrub, to 

 15 ft. : branches with stout hooked prickles: Ifts. usually 

 7-9, rarely less, oblong-ovate or ovate-lanceolate, short- 

 acuminate, rounded or cuneate at the base, sharply 

 serrate, glabrous above, grayish green beneath and 



hairy on the veins, 1-2 in. long: fls. white, fragrant, 

 \Yi in. across, in many-fld. umbel-like corymbs 3-6 

 in. broad; pedicels slender, about 1 in. long, like 

 the receptacles stipitate-glandular, sepals lanceolate, 

 sparsely pinnate; styles hairy: fr. ovoid or oblong- 

 obovoid, scarlet, about J^in. long, with deciduous sepals. 

 June. Cent. China. A handsome free-flowering rose 

 with large clusters of fragrant white fls. in June and 

 scarlet frs. in autumn; has proved hardy at the Arnold 

 Arboretum.

 Koidzumi. R. bracteata, Hort., not Wendl.). MEMO-

 rockeries. A number of hybrids, especially with Hybrid 

 Tea roses, have been raised. G.F. 6:337. Mn. 8, pp. 

 27 and 156. Gng. 6:353-5. Var. rftbra, Andre, with 

 single carmine fls., 1^-2 in. across, and the Ivs. with 

 5-7 somewhat larger Ifts., is a hybrid of R. Wichu- 

 raiana and R. multiflora var. Crimson Rambler. R.H. 

 1901:20. A hybrid with R. rugosa is R. Jdcksonii,

 and of graceful habit. W.R. 20.
