462 KUBUS 



Mr Baker believes it to be a cut-leaved form of a common British bramble 

 called R. Selmeri ; but it comes true from seed and wild plants, sprung no 

 doubt from seed dropped by birds, and may nearly always be found in the vicinity 

 of cultivated plants. It is now extensively cultivated for its fruits in gardens, 

 being perhaps the best of all blackberries for that purpose. The foliage is 

 very handsomely divided, and the plant is sometimes grown on pergolas and 

 trellises for its sake as well as for the fruit. It is useful also for growing on 

 the boundary fences of suburban villas, fruiting freely there. 



Var. ELEGANS. In this bramble (which I am not sure is really a form 

 of laciniatus) the leaves are much smaller, and more hairy on the upper 

 surface. It is known also as " laciniatus minor " and " R. Quintlandii." It 

 does not flower freely and I have never seen the fruit. Grown by lovers 

 of curiosities, 



R. LAMBERTIANUS, Seringe. 



A straggling sub-evergreen shrub, with slender, four-angled stems viscous 

 when young, and armed with short decurved spines. Leaves glossy green on 

 both surfaces, simple, sometimes three-, or obscurely five-lobed, sometimes 

 merely wavy ; broadly ovate or triangular, 3 to 5 ins. long, nearly as much 

 wide at the heart-shaped base, toothed, slightly downy on the veins above, 

 more so beneath; stalk i to 2 ins. long; stipules \ in. long, with usually five 

 linear lobes. Flowers white, \ in. across, produced in a terminal panicle 3 to 

 5 ins. long, calyx segments downy, ovate-lanceolate. Fruit red, small. 



Native of Central China; introduced by Wilson in 1907. It is a luxuriant, 

 very leafy, scandent shrub, suitable for planting as a rough group in thin 

 woodland. 



Var. GLABER (R. hakonensis, Franchei). Similar in habit to the above, 

 stems round and like the leaves smooth or nearly so. Fruits yellow. 

 Native of Japan as well as China; introduced from the latter country by 

 Wilson in 1907. 



R. LASIOSTYLUS, Focke. 

 (Bot. Mag., t. 742'.) 



An erect-growing deciduous shrub, with biennial stems, 4 to 6 ft. high, 

 covered with a blue-white, waxy bloom, and closely set with bristle-like 

 spines, J in. or less in length, not downy. Leaves composed of three or five 

 leaflets, and on young vigorous plants as much as 14 ins. long, but usually 

 some 6 or 8 ins. long, bide leaflets ovate, 2 to 4 ins. long, coarsely and 

 unevenly toothed, very sparsely hairy above, covered with a close white felt 

 beneath ; terminal leaflet much larger especially in the trifoliolate leaves, 

 often lobed, heart-shaped at the base. Flowers small, with reddish purple 

 petals which are shorter than the calyx segments, and soon fall. Fruit 

 i in. across, roundish, red, and downy, with an agreeable acid taste. 



Native of Central China; originally discovered in Hupeh by Henry, who 

 sent seeds to Kew in 1889, from which plants were raised that flowered in 

 1894. This is one of the most striking of the white-stemmed brambles. It 

 has lately been reintroduced in quantity by \\ ilson from Hupeh. 



R. LEUCODERMIS, Douglas. 



A deciduous shrub, 4 to 8 ft. high, with blue-white, erect, biennial stems, 

 armed with stout prickles. Leaves composed of usually three, rarely five, 

 leaflets, which are ovate or lanceolate, i| to 3 ins. long, pointed, doubly 

 toothed, smooth above, covered with a close, white felt beneath. Flowers 

 white, produced during June in terminal clusters. Fruit purplish black, 

 sweet and agreeably flavoured.
