456 RUBUS 



Native of Central China; originally discovered by Henry; introduced to 

 cultivation by Wilson about 1900. Its leaves bear a striking resemblance to 

 those of Tilia argentea. A remarkably distinct as well as rather handsome 

 and effective shrub. I do not know that it has flowered under cultivation. 



R. CORCHORIFOLIUS, LintKZUS fil. 



A deciduous shrub of vigorous growth, spreading by underground suckers; 

 stems erect, 6 to 8 ft. high, branching towards the top, round, covered with 

 an exceedingly fine down -when young, and furnished with rather broad- 

 based prickles. Leaves simple, ovate, with a heart-shaped base ; 3 to 7 ins. 

 long, two-thirds as wide ; those of the sterile sucker stems very deeply 

 three-lobed, purplish when young ; margins irregularly toothed ; upper 

 surface dull dark green, nearly smooth ; the lower one paler and downy 

 about the veins ; midrib spiny ; leaf-stalk I to i ins. long, spiny. Flowers 

 white, borne singly or a few together on short lateral twigs. Fruit large, 

 bright red, and Mr Wilson informs me, of " delicious, vinous flavour.' 3 



Introduced by Wilson in 1907 from Central China, but described and 

 named by the younger Linnaeus as long ago as 1781 from Japanese specimens. 

 It appears to be widely spread in China and Japan. It may prove useful in 

 the wild garden, judging by the way it spreads in borders. 



R. COREANUS, Miquel. 



A deciduous shrub, 8 to 10 ft. high (it has been found 15 ft. high in a wild 

 state), with erect or arching, stout, biennial stems, branching towards the 

 top ; smooth, but covered with a blue-white bloom, and armed with stiff, 

 broad-based spines, up to \ in. long. Leaves pinnate, 6 to 10 ins. long, 

 composed usually of seven "leaflets, which are ovate or broadly oval, from 

 \\ to 3 ins. long, I to 2 ins. wide ; the lateral ones stalkless or nearly so, 

 tapering at the base and smaller than the terminal one, which is broader, 

 rounded or heart-shaped at the base, and stalked ; all are parallel-veined, 

 dark lustrous green, coarsely toothed, except towards the base, and have 

 silky hairs on the veins when young. Flowers borne in flattish clusters 

 terminating short shoots from the wood of the previous year. Fruit of various 

 colours from red to nearly black, edible but small, and of poor flavour. 



Native of Corea and China ; introduced from the latter country in 1907 

 by Wilson, who found it at altitudes up to 6000 ft. It is one of the handsomest 

 of all Rubi in its vigorous blue^-white stems and beautiful pinnate foliage, 

 and may prove a valuable acquisition in gardens should it be quite hardy. 



R. CRAT^EGIFOLIUS, Bunge. 



An erect, deciduous shrub of stiff habit, 6 to 8 ft. high, with stout biennial 

 stems branched towards the top, grooved and armed with small scattered 

 prickles. Leaves on the barren shoots of the year, large, palmately three- or 

 five-lobed, 5 to 8 ins. across ; heart-shaped at the base, sharply and often 

 doubly toothed, downy beneath ; stalks and midrib prickly ; leaves of the 

 flowering twigs much smaller, usually three-lobed. Flowers f to i in. across ; 

 produced in clusters terminating short twigs ; petals white, prettily crimped 

 at the margins ; calyx segments lanceolate, much decurved. Fruit the size 

 of a small raspberry, red. 



Native of China, Corea, and Japan. The name crataegifolius is only 

 appropriate to the small leaves of the flowering twigs; on the barren, first- 

 year stems they are more like those of a vine or maple, and in good soil 

 are sometimes of very large size 8 to 12 ins. across.
