RUBUS 467 



lobed; the side leaflets differ only in being obliquely ovate, stalkless, and 

 much smaller; all are sparsely hairy above, white-felted beneath. Flowers in 

 terminal racemes, the chief feature being the calyx, which is covered with 

 glandular hairs, and measures ii ins. across, the five segments being very 

 narrow and pointed; petals in. or less in length, pink. Fruit conical, | in. 

 long, bright red, sweet and juicy, but of insipid flavour. 



Native of Japan, and the province of Kansu, China; introduced about 

 1876. This raspberry is hardy at Kew, bearing fruit regularly in the open, 

 but it would probably succeed better against a wall. Inla cool house, trained 

 up a post, it bears large crops of its very handsome, brightly coloured fruits. 

 The species is noteworthy, not only for its fruits, but also for its excessively 

 bristly stems, its tiny petals, and large star-shaped calyx which persists and 

 spreads out beneath the fruit. It flowers in June under glass, a few weeks 

 later out-of-doors. 



R. PLAYFAIRII, Hemsley. 



A rambling evergreen or semi-evergreen shrub; young stems dark 

 coloured, round, very slender, string-like, armed with tiny hooked prickles, 

 and covered with web-like down when young. Leaves composed of three to 

 five leaflets radiating from the end of the stalk, which is i| to 2.\ ins. long, 

 and prickly; leaflets lanceolate, sharply toothed, the terminaf one the largest, 

 and sometimes 6 ins. long, the basal pair I to 3 ins. long, dark glossy green 

 above, covered beneath with a pale grey felt. Flowers about \ in. across, 

 produced in small terminal panicles, and in the leaf-axils near. Fruit 

 resembling a raspberry, but black ; ripe in July and August. 



Native of Central and W. China; introduced in 1907 by Wilson, who 

 states that it is found in thickets at 3000 to 6000 ft. It is a very graceful 

 plant when trained up a support, and the shape of its leaves is very uncommon 

 among hardy Rubi, being more suggestive of an Ampelopsis. 



R. SPECTABILIS, Pursk. 

 (Bot. Reg., t. 1424.) 



A deciduous shrub with erect stems, 4 to 6 ft. high, smooth, but armed 

 with fine prickles. Leaves 4 to 6 ins. long, composed of three leaflets which 

 are ovate, from i^ to 4 ins. long, doubly toothed, almost or quite smooth on 

 both surfaces, the terminal one the largest and broadest. Flowers produced 

 singly on short leafy shoots springing from the previous year's wood ; purplish 

 red, i in. or so across, fragrant ; calyx downy, with broad pointed lobes not 

 so long as the petals. Fruit orange-yellow, large, somewhat egg-shaped. 



Native of Western N. America ; introduced by Douglas in 1827. It 

 flowers freely towards the end of April, and is very pretty then. To some of 

 the native tribes of N. America the fruit is valu'able as food, but in this 

 country it does not ripen freely. The plant spreads rapidly by means of 

 sucker growths from the base, and soon forms a dense thicket. Plants should 

 be overhauled annually, and the worn-out stems removed. Propagation is 

 easily effected by dividing up the plants or removing offsets. 



R. STRIGOSUS, Michaux. AMERICAN RED RASPBERRY. 



A deciduous shrub with biennial stems, 3 to 6 ft. high, and densely clothed 

 with bristles which are frequently gland-tipped. Leaves with hairy stalks, 

 composed of three (or five pinnately arranged) leaflets, which are ovate or 

 oblong, 1 1 to 3 ins. long, pointed, coarsely and irregularly toothed, the 

 terminal one stalked, the side ones stalkless, all smooth above, covered with
