358 CLEMATIS 



coarsely toothed, 2 to 5 ins. long, i to 3 ins. wide, either smooth or downy 

 The bases of the common stalks of each pair of leaves are flat, thin, and broad, 

 and surround the stem. Flowers bell-shaped, slightly fragrant, produced in 

 September and October in axillary panicles 4 or 5 ins. long. Sepals soft 

 yellow, oblong, | to I in. long, pointed with the points turned back, finely 

 downy inside. Seed-vessel surmounted by silky plumose styles, i to ij ins. 

 long. 



Native of the Himalaya up to 10,000 ft. It bears some resemblance to 

 C. Rehderiana, but its leaves are not silky, and are especially distinguished by 

 the bioad, flattened stalks at the base; the sepals, too, are not so distinctly ribbed. 

 The flower is rather larger and not so fragrant. It is quite hardy at Kew 

 in the open ground. The species varies considerably in the amount oif down on 

 the leaves and young stems, and in the size of the flattened expansions of 

 the leaf-stalks. 



C. CRISPA, Linnceus. 



(Bot. Mag., t. 1892.) 



A deciduous, half-woody climber, varying from 3 to 8 ft. high. Leaves 

 pinnate, consisting of three, five, or seven leaflets ; these leaflets are themselves 

 often trifoliolate or variously lobed, but not toothed, varying from lance-shaped 

 to broadly ovate with a heart-shaped base, and from i to 3 ins. long by 

 \ to i^ ins. wide, thin and smooth. The larger leaves are altogether 6 to 

 8 ins. long. Flowers solitary on stalks i to 3 ins. long, fragrant ; sepals i| 

 to 2 ins. long, convergent below, spreading and separate towards the points, 

 \ to \ in. wide, thin and wavy at the margins, partially downy at the back, 

 bluish purple, nearly white at the margins. Seed-vessel either silky or 

 becoming nearly smooth. 



Native of the south-eastern United States ; introduced in 1726. This is 

 regarded as one of the Viorna group, but is amply distinguished by the 

 upper half of the sepals expanding widely and being much broadened and 

 wavy at the margin. It flowers from June to August. 



C. DAVIDIANA, Decaisne. 



(C. heraclesefolia var. Davidiana, Franchet.*) 



A semi-shrubby, deciduous plant, up to 4 ft. high ; stems ribbed. Leaves 

 rather leathery, composed of three leaflets, the terminal one the largest ; 

 roundish ovate, shallowly and unequally toothed, from 3 to 6 ins. long, and 

 nearly as much wide, side ones similar except in being short stalked and 

 much smaller. Flowers i J ins. across, produced in dense axillary clusters ; 

 the base is tubular, but the four sepals are spreading (not curled back 

 as in C. tubulosa), indigo-blue outside. Male and female flowers occur 

 on separate plants. 



Native of China ; introduced to Paris in 1864 by the Abbe David, after 

 whom it is named. It is, perhaps, the most desirable of the tubulosa 

 group. From C. tubulosa itself it differs in its taller habit ; the plants are 

 unisexual (dioecious), and the sepals are larger, longer, and do not curl 

 back. At the same time the late Mr Franchet made Davidiana a variety 

 simply of the other. 



C. DURANDII, Kuntze. 



(Garden, Feb. 8, 1896, t. 1052.) 



A robust climber, growing 9 ft. high, with stout stems. Leaves undivided, 

 ovate, pointed, tapering or slightly heart-shaped at the base ; ^ to 6 ins. long, 

 about half as wide, with three or five longitudinal veins, firm-textured,
