Editorial Note
Bean treated this species under the name Clematis fargesii var. souliei.
A deciduous climber 20 ft high, with strongly ribbed, purplish, downy young shoots. Leaves up to 9 in. long, composed of five primary divisions each consisting of three leaflets; all the stalks downy. Leaflets ovate, pointed, wedge-shaped to truncate at the base, unevenly and coarsely toothed, sometimes three-lobed; 1 to 2 in. long, 1⁄2 to 11⁄2 in. wide; the terminal one usually more than twice the size of the side ones, which are shortly stalked to stalkless; both surfaces downy, dullish green. Flowers up to 21⁄2 in. wide, pure white, produced from the leaf-axils, singly or a few together on a main-stalk 3 to 6 in. long. Sepals six, obovate, 1⁄2 to 3⁄4 in. wide, each with a short abrupt point; tinged with yellow and downy outside. Stamens with glabrous stalks and pale yellow anthers. Seed-vessel with a feathery style. Bot. Mag., t. 8702.
Native of W. China; introduced by Wilson in 1911. It is quite hardy at Kew and grows freely. Whilst it does not make a great display at any one time the flowers are attractive in their pure whiteness and satiny texture and they continue to appear from June to September.
[Among the various taxa discussed by Bean, but since reduced to synonymy, C. fargesii Franch. – ‘perhaps not in cultivation in this country’ – was said to be distinguished from var. souliei by the proportionately larger anthers in comparison with the filaments, and by the leaflets being ‘more rounded at the base and more downy.’]
