A new species of Heterostemma, H. barikiana, is described and illustrated. The new species is similar to Heterostemma xuansonense in the absent or very reduced peduncle and in the presence of a pubescent staminal corona.

In their monumental work Flora Indica, Hooker and Thomson (1855) described two new species under the genus Delphinium Linnaeus (1753: 530), namely D. viscosum Hooker f. & Thomson (1855: 52) and D. glaciale Hooker f. & Thomson (1855: 53) from the Sikkim Himalaya. In due course of revisionary studies in the genus Delphinium from India, the taxonomic difficulties associated with D. viscosum were addressed and resolved as a complex (Agnihotri et al., 2016). A thorough search of various national and international herbaria (BM, BSI, CAL, E, GH, JE, K, MEL, MH, NY and S: acronyms according to Thiers 2017 onwards) and a detailed study of both D. glaciale and D. viscosum complex have revealed that three names remain surrounded by uncertainty in typification. Therefore, a lectotype for the names D. glaciale, D. viscosum subsp. viscosum and D. viscosum subsp. gigantobracteum is selected here from amongst the original material.

During our ongoing revisionary studies of the genus Gentiana in India, we found that no lectotypes for the names G. elwesii C.B. Clarke, G. gilvostriata C. Marquand and G. listeri Burkill have been designated, which are here proposed.
