Native of China, mainly in the provinces of Szechwan and Kansu; introduced in 1908. It was successfully grown and flowered by the late Lord Wakehurst in his garden near Ardingly in Sussex.
C. integrifolia Maxim. Introduced by Wilson from W. China in 1908, this is very near C. actinidioides and has, in fact, been made synonymous with it in the Botanical Magazine. The leaves are glabrous and glaucous beneath. It climbs 20 to 25 ft high, the flowers white and fragrant. Discovered by Potanin, the Russian traveller, in Kansu, in 1887. The name integrifolia does not entirely fit the plants now attributed to the species, for they have finely bristle-toothed leaves.
C. lasioclada Maxim. has downy, not bristly, young shoots. The leaves are ovate, 2 to 4 in. long, bristle-toothed, and have tufts of down in the vein-axils beneath; stalks up to 21⁄2 in. long. Flowers white, in cymes of two to seven blossoms. Fruit globose, 1⁄3 in. wide, black. This is a climber 20 to 25 ft high according to Wilson, who introduced it from W. China in 1908.
