south-facing slope. Flowers pale creamy yellow, with a small 
deep purple blotch at base of corolla, nearly regular. Leaves 
silver beneath. Only one tree seen. F. Kingdon Ward. No. 
3061. May 25, Igig. 
May 28. Many trees seen between 8000 and gooo ft. from 
the beginning of the shrub belt up but they seem to bear very 
few flowers. Perhaps they do better on N.-facing slopes.— 
A beautiful species of the Grande series. The first record 
of the plant is in Capt. Abbay’s specimens which at first were 
supposed to be Rh. grande, Wight, and then were referred to 
Rh. arboreum, Sm. Abbay’s specimens have imperfect flowers 
only. Now we have it in good state from each of the three 
explorers, Farrer, Forrest, Ward, who have been collecting 
in N.E. Burma and W. Yunnan within a few miles of each 
other during last year. The plant comes in the series near 
the Himalayan Rh. argenteum, Hook. f., and Rh. grande, Wight, 
but it wants the glandular ovary of these species.

cushion with straight branchlets reddish-brown of short annual
