Clematis tangutica - Orange-Peel Clematis

Orange-Peel Clematis is a climbing or straggling shrub, with stems up to 3-4 m long, green when young, slender, finely velvet-hairy to nearly hairless. Flowers are borne at branch-ends or in leaf-axils, usually solitary, though sometimes 2-3 together on a short flower-cluster-stalk, lemon yellow, sometimes tinged with brown or purplish-brown on the exterior, nodding with narrowly or widely spreading sepals. Flower-cluster-stalk 0.6-3 cm long. Bracts are like the leaves but generally smaller and trifoliate or trilobed. Flower-stalks are 4-3-32 cm long, slender, sparsely velvet-hairy to hairless. Sepals are lanceshaped-elliptic to oblong, pointed, tapering or blunt, 1.8-3.4 x 0.7-1.6 cm, finely and silky velvet-hairy outside, hairless inside. Filaments are 5-10 mm long; anthers 2-3 mm long. Styles are up to 5.5 cm long in fruit. Leaves are pinnate with 5-7 leaflets, rarely more or less double compound; leaflets green, lanceshaped to narrow-elliptic to oblong, 1-3-5-7 x 0-4-2 cm, unlobed or lobed near the base, the tip pointed or tapering, the margin unevenly incise sawtoothed in the lower two-thirds, hairless or sparsely velvet-hairy above, velvet-hairy to nearly hairless beneath. Orange-Peel Clematis is found from Central Asia to China and West Himalaya, at altitudes of 3000-4900 m.
