In Rhododendron and Fir forest. Tree or shrub 8-15 ft.

Flowers deep fleshy crimson, with deep magenta patches at base ; calyx irregular, large, same colour, and also fleshy ; style and filaments white; anthers red brown ; stigma deep red. 26th May 1936.” Ludlow and Sherriff, No. 1710. Type in Herb. Brit. Mus. A plant somewhat resembling Rh. fulgens Hook. f. but with a very large, rather irregular, fleshy calyx, recalling the calyx of Rh. diphro- calyx Balf. f. and of some forms of Rh. neriiflorum Franch. I prefer to place this species in the Campanulatum Series rather than in the Neriiflorum Series, although the comparatively loose few-flowered truss, and the leaf with its woolly indumentum on the underside, suggest a linkage with the Haematodes subseries. However, in all the different subsections of the Neriiflorum Series the ovary is densely hairy, or glandular, or hairy and glandular, never glabrous as in Rh. fulgens and in Rh. miniatum, and never sparsely floccose,
