RUBUS 



RUBUS 



2193. Rubus deliciosus, from the Rocky Mountains- 

 prickles, glabrous^ or nearly so: Ivs. thin and soft, light 

 green, with 3 or 5 ovate or rhuntbic-ovate, coarsely ser- 

 rate Ifts.: fls. 1-3 on each peduncle, small and white, 

 the calyx reflexed: fr. small, reddish. Cold swamps, 

 N. J. west and north.— Offered as a rock garden plant 

 for moist places. 



3. xanthocArpus, Bur. & Franchet [R. Potanini, 

 Regel). Trailing, the stems dying back every year, the 

 stems pilose and weak-spiny; Ivs. pinnately 3-foliolate, 

 the leaflets ovate, acute or obtuse, strongly and un- 

 equally dentate, the terminal one twice larger than the 

 others: tls. solitary or twin in the axils of the upper Ivs., 

 the peduncle and calyx weak-prickly, the petals white: 

 fr. large, ovate, bright yellow, fragrant and palatable, 

 the calyx persistent China; discovered in 1885 in the 

 Province of Kansu, 40° north latitude, and later found 

 in provinces Sze-Chuen and Yun-nan.— Int. into the 

 U. S. in 1898 by the Dept. of Agric. through Professor 

 N. E. Hansen, to be tried for its edible raspberry-like 

 fruit. At Brookings, 8. Dakota, the plants suffered from 

 the phenomenal winter of 1898-9, but mulched plants 

 have subserniently endured the winters well.

4. trifidus, Thunb. Fire Raspbekuv. Strong-grow- 

 ing and erect, 7-lU ft. tali: Ivs. large, palmately ribbed, 

 3-5- or even 7-cleft, serrate: lis. subsolitary, the pe- 

 duncles villous; berrj- of medium size, scarlet, with 

 pointed drupelets. Japan. — Sparingly introduced, and 

 prized for its bright autumn foliage (whence the name 

 "Fire Raspberry ").

 Raspbekry. Fig. 2193. Compact, bushy grower, reach- 

 ing 5 ft.: Ivs. large, orbicular or reniform, shallowly 

 3-5-lobeil, unequally serrate, somewhat glandular: fis. 

 borne in great profusion, pure white, 1-2 in. across, in 

 early summer iind continuing for a long season: berrj"" 

 hemispherical, purplish or wine-color, with large, soft 

 drupelets like those of a red R;ispberry, edible but not 

 esttjumed for eating. Rocky Mountains, reaching 8,000 

 ft. elevation. B.M. G0G2. G.C. IT. 15:o3T. R. PI. 1882, p.

 — One of the finest of native dowerin.tr Raspberries, and 

 deserving to be known. Hardy in i\lass. The fls. re- 

 semble single roses.

 with the shreddy canes reaching 3-0 ft. :" lvs. very large, 

 pubescent beneath, 3-5-lol.)ed, "the lobes pointed, mar- 

 gins serrate: Ms. 1-2 in. across, rose-purple, several to 



many in the cluster, the sepals with a long point, the 

 peduncles and pedicels glandular-pubescent: berry llat- 

 tisli and broad (% in. across), rather dry, light red, 

 edibb.' but not valued. Nova Scotia to Mich, and Georgia 

 (Fla. 0- Gn. 34, p. 230. B.M. 323. J.H 111.31:133.- 

 I'refers rich shady woods and banks. It makes a bold 

 subject in a toliage mass, and its lis. are nearly a.s large 

 as single roses, although the color is less bright. It 

 spreads rapidly from the root and overtops weaker plants. 



7. parvifldrus, Nutt. (i?. JS^utkdmts, Moc.). Differs 

 from the last in having white tls. in few-tid. clusters 

 and less glandular peduncles. N. Mich, to the Pacific 

 coast and southward in the Rockies: the western rep- 

 resentative of i?. odoratus. B.M. 3453. B.R. 10:1368.

a. Lvs. simple, hut more or less lohed . 



8. microphyllus, Linn. f. {R. palmittu.s, Thunb.). 

 Spreading, often slender-stemmed plant growing 4 or o 

 ft. tall, with many short, but stout nearly straight 

 spines: lvs. rather small, 2-3 in. long as a rule, narrow- 

 ovate-acuminate or sometimes nearly triangular-ovate- 

 acuminate, rather deeply 3-5-lobed and the middle lobe 

 long and acuminate, the margins very sharp-serrate: 

 hs. white, nearly or quite ^4 iu. across, with broadly 

 ovate petals: fr. small (red ?), of little value. Japan.— 

 Sparingly introduced as an oraameutal plant, but little 

 known here. The "Mayberry," introd. by Luther Bur- 

 bank, is said to be a hybrid between this species and 

 the Cuthbert Raspberry (R. strigosus). The Mayberry 

 is described as producing a large yellow edible berry, 

 ripening in advance of the Strawberry. 



9. crataegifolius, Bunge. Fig. 2195 (after Card). Strong, 

 erect or diffuse much - spreading plant (3-5 ft.), with 

 terete reddish glabrous canes that bear few and small 

 straight spines: lvs. obloug-ovate to cordate-ovate, acu- 

 minate, 3-5-lobed, and the margin coarsely serrate and 

 notched: fls. white, in small clusters terminating slen- 

 der leafy shoots, about ?^ in. across: fr. small, orange- 

 red, of no value. Japan. — An excellent plant for hold- 

 ing banks and for covering waste places, and giving 

 fine deep reds in the fall. Perfectly hardy in central 

 New York. Burbank's "Primus" is hybrid of this ami 

 R. vitifoUus, the latter furnishing the seed. 



10. Savati^ri (R. morifbHus, Sieb.. Pranch. & Savat. 

 Enum. PL Jap. (1875), not Muell. 1858). Differs from 

 R. crutivgifoll'us by its more numerous and stronger 

 prickles, the leaves villous beneath and deeply cordate 

 at base, shoi-ter petioles and shorter and thicker pedi- 

 cels. Southern Japan. — Offered by dealers in Japanese 

 plants, who speak of its pretty fruit ripening in July.
