RUBUS 461 



R. KOEHNEANUS, Focke. 

 (Bot. Mag., t. 8246.) 



A deciduous shrub of bushy, rounded habit, a few feet high ; the erect, or 

 nearly erect, biennial stems covered with purplish bloom, but with few or 

 no prickles. Leaves simple, three- or five-lobed, or sometimes scarcely 

 lobed at all, heart-shaped at the base, \\ to 5 ins. long, about the same wide ; 

 smooth and green above, white but not downy beneath ; margins sharply 

 toothed ; leaf-stalk often as long as the blade. Flowers f in. across, 

 produced usually three together ; stalks smooth, f in. long ; petals white, 

 oblong, calyx downy within, the triangular lobes shorter than the petals. 

 Fruits orange red, composed of comparatively few large carpels. 



Native of Japan ; introduced by Spath of Berlin, and originally distributed 

 as " R. morifolius. 3 ' It is also grown sometimes under the erroneous name of 

 "R. incisus." It is rather pretty in blossom, the flowers being abundant, 

 and the purple-red anthers contrasting well with the white petals. 



R. KUNTZEANUS, Hemsley. 



A deciduous shrub, with erect, sturdy biennial stems, 6 to 10 ft. high, 

 branching towards the top, covered with soft, grey, velvety down, and armed 

 with short broad-based, scattered prickles. Leaves from 6 to 12 ins. long, 

 composed of three or five (pinnately arranged) leaflets, the side ones of 

 which are obliquely ovate, 2 to 4 ins. long, i to i\ ins. wide ; fine-pointed, 

 rounded at the base, irregularly toothed and very^shortly stalked ; slightly 

 hairy and dark glossy green above, covered beneath with a close white felt, 

 interspersed with hairs on the veins ; terminal leaflet larger, broader, longer- 

 stalked, often three-lobed, and heart-shaped at the base. The main-stalk has 

 hooked prickles and is covered with the same velvety down as the stem. ' 

 Flowers small (-g- to \ in. wide), produced in large terminal panicles, I to 

 i^r ft. long ; petals pink and soon falling. Fruit orange-red, rounded, \ to 

 I in. wide, of good flavour. 



Native of Central and W. China ; first introduced to Kew by Henry from 

 Ichang in 1886, but most of the plants now in cultivation were introduced by 

 Wilson between 1900 and 1907. The species is of some promise as a fruit- 

 bearer, but has little to recommend it for ornament. It has been confused 

 with R. INNOMINATUS, 5". Moore, a species very closely allied, but distinct in 

 its glandular stems, leaf-stalks, inflorescence, and calyx. Probably not in 

 cultivation. Central China. 



R. LACINIATUS, Willdenow. CUT-LEAVED BRAMBLE. 



A deciduous shrub of rambling or scandent habit, the angled stems well 

 armed with stout, recurved spines, and hairy. Leaves composed of five 

 (sometimes three) leaflets, radially arranged ; the common stalk 2 to 3 ins. 

 long, beset with hooked spines. Leaflets stalked, and either pinnate, or 

 deeply and pinnately lobed ; final subdivisions of leaf coarsely and angularly 

 toothed ; spiny on the stalk and midrib ; downy especially beneath. The 

 leaves vary much in size, and on vigorous shoots will, including the stalk, 

 reach 8 to 12 ins. in length. Flowers in large terminal panicles ; flower-stalk 

 hairy and spiny ; petals pinkish white ; calyx with narrow, downy, reflexed 

 segments spiny at the back, \ to f in. long, ending in a tail-like point. Fruit 

 black, and both in size and flavour one of the finest of blackberries. 



The origin of this handsome and useful bramble is not known. It was 

 first distinguished by Willdenow in the old botanic garden of Berlin in 1809..
