RUBUS 



RUBUS 



nate, irregularly serrate, 4-5 in. long, deep metallic 

 green on upper surface: fls. white, on growths of 6-8 in. 

 long: fr. medium in size, glossy black. Cent, and W. 

 China, 4,000-6,000 ft. R.B. 33, p. 360. Useful on 

 posts and pergolas. 



23. moluccanus, Linn. A large raspberry-like plant 

 in many forms, common in India and Malaya, and to 

 be expected as an intro. plant in many warm countries. 

 Very robust, the tomentose canes and branches red- 

 hairy and with short curved scattered prickles: Ivs. sim- 

 ple, very variable, large, usually hairy, gray- 

 or yellow-woolly beneath, mostly broad-ovate 

 or orbicular and deep-cordate, shallowly 3-5- 

 lobed, irregularly ser- 

 rate: fls. white, in con- 

 tracted terminal clus- 

 ters: fr. in shades of 

 red, succulent. Gn. 63, 

 p. 408. G.M.46,p.323. 

 Probably not in the 

 American trade. 



3491. Rubus spectabilis of western America. The salmonberry. 

 (No. 32.") 



24. reflexus, Ker. Tall stout climber sometimes con- 

 fused with R. moluccanus: prickles few and scattered: 

 young growth, petioles, and under surface of Ivs. bear- 

 ing cinnamon-colored pubescence: Ivs. simple but 

 sometimes prominently 3-5-lobed, broad-ovate or 

 ovate-oblong in outline, base cordate, margins toothed, 

 prominently nerved beneath, the terminal lobe long: 

 fls. white or pink, %in. or less diam., nearly sessile in 

 small few-fld. declined clusters: fr. small, globular, red- 

 purple or black. China. B.R. 461. B.M. 7716. Var. 

 pictus, W. Wats., has the Ivs. velvety green, and gray- 

 variegated above and soft pale cinnamon-brown 

 beneath: handsome. G.C. III. 33 : 309 (as R. moluc- 

 canus). R.B. 29:237. 



Section VI. ID.EOBATUS. Raspberries. 

 A. Lvs. simple, often 3-lobed on strong shoots. 



25. corchorifdlius, Linn. f. Nearly or quite erect, 

 4-6 ft., the terete sts. downy and bearing small straight 

 spines: Ivs. simple, cordate^ovate, mostly 3-lobed on 

 the verdurous shoots, 4-7 in. long, dull green above 

 and pubescent beneath, the margins coarsely toothed, 

 midrib and petiole with hooked prickles: fls. white, 

 solitary, on short lateral twigs: fr. bright red, large, 

 said to be excellent in quality. Cent, and W. China, 

 to 7,000 ft. altitude. Japan. G.C. III. 51:149. There 

 are several forms or very closely related species. 



26. palmatus, Thunb. Spreading, often slender- 

 stemmed plant growing 4-5 ft. tall, with many short, 

 but stout nearly straight spines: Ivs. rather small, 2-3 

 in. long as a rule, narrow-ovate-acuminate or sometimes 

 nearly triangular-pvate-acuminate, rather deeply 3-5- 

 lobed and the middle lobe long and acuminate, the 

 margins very sharp-serrate: fls. white, nearly or quite 

 %in. across, with broadly ovate petals: fr. small (red?), 

 of little value. China, Japan. B.M. 7801. Sparingly 

 intro. as an ornamental plant, but little known here. 

 The May berry, intro. by Luther Bur bank, is said to be 

 a hybrid between this species and the Cuthbert rasp- 

 berry (R. strigosus). The May berry is described as 

 producing a large yellow edible berry, ripening in 

 advance of the strawberry. R. palmatus is doubtfully 

 referable to R. microphyllus, Linn, f . 



27. crataegif&lius, Bunge. Fig. 3490. Strong, erect or 

 diffuse much-spreading plant (3-5 ft.), with terete red- 

 dish glabrous canes that bear few and small straight 

 spines: Ivs. oblong-ovate to cordate-ovate, acuminate, 

 3-5-lobed, and the margin coarsely serrate and notched: 

 fls. white, in small clusters terminating slender leafy 

 shoots, about Kin- across: fr. small, orange-red, of no 

 value. China, Japan. An excellent plant for holding 

 banks and for covering waste places, and giving fine 

 deep reds in the fall. Perfectly hardy in Cent. N. Y. 



28. Savatieri, Bailey (R. morifdlius, Sieb.; Franch 

 & Savat. Enum. PI. Jap., 1875, not Muell., 1858. R. 

 crategifdlius var. morifdlius, Focke). Differs from R. 

 crategifolius by its more numerous and stronger 

 prickles, the Ivs. villous beneath and deeply cordate at 

 base, shorter petioles and shorter and thicker pedicels. 

 Japan. Offered by dealers in Japanese plants, who 

 speak of its pretty fr. ripening in July. 



29. trianthus, Focke. Wide-spreading deciduous 

 shrub, glabrous: sts. erect, and much branched, blue- 

 white, prickly, 4-6 ft.: lys. simple, more or less 3-lobed, 

 3-6 in. long, ovate to triangular: fls. pink-white, small: 

 fr. dark red, of 10-30 carpels. Cent. China. 



30. conduplicatus, Duthie, perhaps the same as R. 

 trianthus, but described as differing in the pale green 

 (not white) under surfaces of Ivs., smaller fls., prickles 

 on st. stronger and more curved. China. A scandent 

 glandless shrub, with simple petiolate Ivs. which are 

 ovate-lanceolate and acuminate and sometimes ob- 

 scurely 3-lobed, the margins unequally incised-serrate : 

 fls. 3-4, terminal, white. 



31. Koehneanus, Focke (R. incisus, Hort., not 

 Thunb. R. morifdlius, Hort., not Sieb.). Nearly erect 

 shrub, 3-4 ft. high, the branches with purplish bloom 

 and unarmed or sparingly prickly: Ivs. simple, varying 

 from almost entire to 3-5-lobed, 5 in. or less long, and 

 nearly as broad, mostly deep-cordate at base, green 

 above and white-pubescent beneath, the lobes more or 

 less acute, petioles somewhat prickly: fls. few, in loose 

 terminal corymbs, white, the petals about H m - long: 

 fr. small and globose, orange. Japan. B.M. 8246. 

 Gt. 53, p. 555 (as R. indsus). 



AA. Lvs. ternately compound, running to o-foliolate forms, 



often on the pedate order. 

 B. Fls. large, solitary or few together. 



32. spectabilis, Pursh (Parmena spectabilis, Greene). 

 SALMONBERRY. Fig. 3491. Strong-growing, reaching 

 5-15 ft., glabrous: spines few or often none, weak: Ivs. 

 of 3 ovate-acuminate Ifts., which are doubly serrate- 

 toothed and sometimes indistinctly lobed, long-stalked, 

 thin, glabrous or becoming so beneath: fls. solitary or in 

 2's, large, red or purple: fr. large, somewhat conical, 

 salmon-color or wine-red, edible, the drupelets bearing 

 the persistent styles. Calif, and Idaho to Alaska. B.R. 

 1424. L.B.C. 17:1602. F.S. 21:2260. Mn. 4, p. 57. 

 Sometimes cult, for its showy fls. and frs. Canes 

 perennial. Var. Menziesii, Wats. (R. franciscanus, 

 Rydb.), has Ivs. densely pubescent or silky underneath.
