Flowers produced in April in terminal clusters of three to six. Calyx reddish, 14 to 13 in. long, deeply five-lobed, the lobes scaly outside and fringed with bristles; flower-stalk 12 to 34 in. long. Corolla widely funnel-shaped, 1 to 112 in. long and wide, five-lobed, deep rose coloured, downy in the throat. Stamens ten, their white stalks with a tuft of down towards the base; anthers brown, well exposed. Ovary scaly; style slender, glabrous, 1 in. long. Bot. Mag., t. 9561. (s. Lapponicum)

R. cuneatum was found by Forrest in 1910 in the Lichiang range, N.W. Yunnan, growing on the margins of pine forests at 12,000 ft. His later collections are all from the drier parts of N.W. Yunnan and S.W. Szechwan, where it is apparently always found on limestone. It is at present placed in the Lapponicum series, with which it disagrees in its habit, large leaves, and in the shape of the corolla, which is funnel-shaped and zygomorphic, whereas in the Lapponicum series it is near to rotate in shape, i.e., has a tubular base abruptly widening into the limb. It is a hardy, quite pretty species, flowering in April.
