Abstract: YUNNAN : Lichiang Range (Forrest 2437, 5766, 6046, 15068) ; Tali Range (Forrest 4412); mountains north-east of Chungtien (Forrest 16783) ; sine loc.(Forrest 28139, 3°97 8 ) 5 slopes of Mt.Gyi-na-lo-ko, the second peak of the Yu-lung Shan (Rock 24989).SIKANG : Mountains south-east of Muli (Forrest 22171).This Himalayan and Chinese plant is of course usually known as P. fruticosa Linn.North America is apparently the headquarters of the Linnean plant for it is common in Canada and the United States, extending as far west as the Rocky Mountains.Elsewhere it is confined to a few detached localities in England, Ireland, Europe and the Altai.It is not to be found in the Himalaya nor in China.Here its place is taken by P. arbuscula Don, a very plastic species with a distributional range extending from Kashmir throughout the Himalaya to Yunnan, Sikang and Kansu and eastwards to Shansi and Hopei (Chili).The two plants can readily be separated by the reticulation of the leaves ; this in P. arbuscula is extremely close whereas in P. fruticosa it is much laxer ; moreover, the leaves of the former are far thicker and firmer in texture than those of the latter.The typical plant is glabrous on the lower leaf-surface, whereas the upper surface is covered with long white silky hairs.P. arbuscula var.albicans (Rehd.et Wilson) Hand.-Mzt. in Symb.Sin., VII, 508 (1933)-excl.specim.3930 and in Acta Hort.gothoburg, XIII, 292, (1939).P. fruticosa var.albicans Rehd.et Wilson in PI.Wil., II, 302 (1916).
