RUBUS 



3029 



evergreen in warm countries, glabrous or somewhat 

 pubescent-hirsute: Ivs. odd-pinnate, the lateral Ifts. 

 2-7 pairs, all the Ifts. ovate-lanceolate or lance-oblong, 

 acuminate, strongly many-veined and very sharp-ser- 

 rate, more or less silky-hairy beneath: fls. solitary or in 

 few-fld. clusters, white, 1^-2 in. across, showy: fr. 



3496. Gregg raspberry, a cultivated form of Rubus occidentalis 

 No. 46. 



erect, bright red, long thimble-shaped, usually about 

 1-1 ]/2 in. high, very showy, edible but insipid. Widely 

 distributed in tropical countries, but native to the 

 Himalayan region and eastward to China and Japan; 

 naturalized in W. Indies. EM. 6970. F.S. 17:1714. 

 A.G. 20:82, 87. Var. coronarius, Sims (R. grandiflorus, 

 Hort.), is a double form, sometimes cult, as the ''Brier 

 Rose" and "Bridal Rose" (B.M. 1783. G.C. II. 11:77. 

 G.Z. 26, p. 266). The double-fld. form is often grown 

 under glass and in pots. 



49. illecebrosus, Focke (R. sorbifolius, Hort., not 

 Maxim.). STRAWBERRY-RASPBERRY, Figs. 3497, 3498, 

 from Japan, is a dwarf glabrous but prickly undershrub 

 with pretty pinnate foliage, and white fls. 1% in. across, 

 and scarlet fr. Gn. 64, p. 412. A.G. 24:603. A beau- 

 tiful plant and worthy of general cult. In the N. it 

 usually kills to the ground each winter, but it throws 

 up shoots 2-4 ft., and these bloom from summer until 

 frost, usually ripening fr. at the same time. The fr. has 

 some value for eating, but it is probable that it will 

 never be greatly developed in this direction. R. illece- 

 brosus is suckering: sts. angular, glabrous, prickly: Ifts. 

 5-7, oblong-lanceolate, acuminate, duplicate serrate, 

 pilose on the veins beneath, otherwise nearly glabrous: 

 fls. terminal and axillary, solitary or few, bracted. 

 How much of the cult, material belongs to this species 

 and to Xo. 48 is to be determined. 



50. coreanus, Miq. Of upright or erect growth, with 

 straight prickles on the sts. and hooked prickles on the 

 petioles, self-supporting, 6-7 ft. or more high, the sts. 

 hoary, bluish white and the young growths dark brown : 

 Ivs. pinnate, 7-9 in. long, usually of 7 or 9 ovate serrate 

 pointed light green Ifts.: fls. rose or purple, in large 

 terminal panicles: fr. said to be of no value. China, 

 Korea. G.C. III. 51:149. 



51. amabilis, Focke. Shrub, 6 ft., slightly prickly 

 or unarmed above: Ivs. pinnate, with about 9 ovate or 

 ovate-lanceolate, deeply double-serrate Ifts. 2 in. or less 

 long, the petiole and rachis weak-prickly, the stipules 

 small and linear: fls. solitary, terminal, large (about 2 

 in. across), white: fr. large and red, of good flavor. W. 

 China. 



52. flosculdsus, Focke. Erect, about 7 ft., the dark 

 brown sts. bearing stiff prickles: Ivs. pinnate, silvery 

 white beneath, with 5-7 Ifts. which are distant, lanceo- 

 late or narrowly rhomb-lanceolate, serrate, white- 

 tomentose beneath: fls. about 12, small, pale purple, in a 

 panicle, appearing in Sept. : fr. small (size of a pea), dark 

 red becoming black. Cent, and W. China, 4,000-6,000 ft. 

 63. thibetanus, Franch. (R. VeUchii, Rolfe). A 

 curious deciduous rubus, said by Focke to represent 

 perhaps the type of a well-marked section in the 

 genus: shrub with terete prickly branches and graceful 

 fern-like foliage: sts. at first erect, but arching with age, 

 blue-white: Ivs. 6-9 in. long, pinnate, with 5-11 elliptic 

 or ovate coarsely toothed Ifts., puberulous or silky- 

 hairy above and white beneath, the terminal 1ft. ovate- 

 lanceolate or rhomboid and 2-3 in. long and sometimes 

 almost pinnatifid: fls. rose-purple, in terminal few-fld. 

 prickly and pubescent panicles, the orbicular-obovate 

 petals small: fr. globose, red or blue-black, of moderate 

 size. W. China. G.C. III. 51 : 149. 



54. niveus, Thunb. Very strong-growing, the sts. 

 reaching 12 ft. and 3 in. circum. with many stiff brown 

 hairs and small spines, arching at the ends: Ivs. pinnate, 

 with 3-11 Ifts. variable in shape but mostly rhomb- 

 oblong or ovate-oblong, coarsely serrate, whitish- 

 tomentose beneath, the lateral ones scarcely stalked: 

 fls. small, white, many in terminal and axillary 

 panicles: fr. dull black, of medium size. Cent, and 

 W. China, 3,000-8,000 ft. altitude. 



55. Giraldianus, Focke. Said to be an elegant 

 bush reaching 8-9 ft. in height, the sts. white, 

 branching and gracefully curving above, terete, gla- 

 brous, prickly: Ifts. usually 7, the terminal ovate- 

 lanceolate, the lateral oblong-lanceolate, unequally 

 coarsely serrate, glabrous above, tomentose beneath: 

 fls. in terminal panicles, 4-5 in. long, small, white: fr. 

 black. N. and Cent. China. Gn. 76, p. 624. G.C. III. 

 51:147 (as an unnamed species). 



Section VII. EUBATTJS. Blackberries and Dewberries. 



A. Blackberries: plant usually erect or essentially so (strong 

 canes often recurving and very long ones often repent) . 



B. Species exotic, with mostly perennial canes, and fls. 



usually borne on the ends of the main shoots. 

 56. thyrsanthus, Focke. A vigorous species, with 

 suberect or decumbent canes which are prostrate when 

 very long, the strong prolonged sts. angled and 



3497. Rubus illecebrosus. One of the best flowering rubuses.
