Abstract: Two new species, both related to H. hookerianum Wight & Arn., are described from northern Yunnan, H. fosteri N. Robson and H. wardianum N. Robson. The former is apparently endemic, having been found in only one locality, whereas the latter also occurs in north-eastern Myanmar. Both differ in particular from H. hookerianum in that the capsule is elongate, not ovate-subglobose and the sepals are not ribbed. In addition, H. bellum ssp. latisepalum is raised to specific rank as H. latisepalum (N. Robson) N. Robson and the variable H. lagarocladum is divided into two subspecies, one broad-leaved with a spreading habit (ssp. lagarocladum) and the other narrow-leaved and more erect (ssp. angustifolium N. Robson).
