Bhutanthera albomarginata (King & Pantling) Renz (Edinbugh J. Bot. 58: 101. 2001; Habenaria albomarginata King & Pantling, Ann. Roy. Bot. Gard. Calcutta 8: 322. 1898) has been noted from Xizang (Press et al., Annot. Checkl. Fl. Pl. Nepal, 217. 2000). However, the present authors found no relevant specimens and therefore could not substantiate the occurrence of this species in China.
