One new genus (Setulocarya R.R. Mill & D.G. Long, belonging to tribe Eritrichieae and allied to Microcaryum I.M. Johnst.: Himachal Pradesh, Nepal, Sikkim) and four new species (Hackelia bhutanica R.R. Mill and H. obtusifolia R.R. Mill, both from Bhutan and Sikkim, Lasiocaryum ludiowii R.R. Mill from Bhutan, Nepal and Tibet, and Trigonotis clarkei R.R. Mill from Darjeeling) are described. The new combinations Setulocarya diffusa (Brand) R.R. Mill & D.G. Long and Onosma emodi Wall. var. stelligera (I.M. Johnst.) R.R. Mill are made. Tournefortia hookeri C.B. Clarke is lectotypified and the typification of Microula pustulosa (C.B. Clarke) Duthie is clarified.

The taxonomy and typification of Ehretia wallichiana Hook.f. & Thomson and allied species (Boraginaceae, subfamily Ehretioideae) are discussed. E. wallichiana is lectotypified; the species occurs from Nepal to Assam. The identity of Cordia acuminata Wall, is discussed and the name is lectotypified. Its type is here treated as Ehretia silvana R.R. Mill nom. nov. Three new species. E. exsoluta R.R. Mill sp. nov., E. psilosiphon R.R. Mill sp. nov., and E. dolichandra R.R. Mill sp. nov., are described and their affinities discussed. A key to all the species of the ‘E. wallichiana complex’, together with contusable species occurring from India to China, is given.

Ten new species of Umbelliferae are described from Bhutan, Nepal and Sikkim: Cnidium atropurpureum M.F. Watson, Cortiella lamondiana Fullarton & M.F. Watson, Heracleum bhutanicum M.F. Watson, H. woodii M.F. Watson, Keraymonia pinnatifolia M.F. Watson, Schulzia bhutanica M.F. Watson, Sinocarum longii M.F. Watson, S. minus M.F. Watson, S. pulchellum M.F. Watson and S. woodii M.F. Watson. Two new combinations are made: Cortiella cortioides (C. Norman) M.F. Watson and Meeboldia digitata (Kljuykov) M.F. Watson.

The synonymy of Asplenium unisodontum C.Presl (Aspleniaceae) in the Philippines is clarified. Asplenium anisodontum C.Presl. A. longissimum Blume and A. caudatum G.Forst. are different species. A. anisodontum C.Presl and A. longissimum Blume are both found in the Philippines. The presence of Asplenium cuudatum G.Forst. in the Philippines is doubtful. Asplenium acutiusculum Blume is the same as A. longissimum Blume and the latter name should be accepted.
