The following new species are described from the E Himalaya: Poa pseudotibetica Noltie (Tibet, Sikkim); P. rohmooiana Noltie (Sikkim); P. chumbiensis Noltie (Tibet); P. dzongicola Noltie (Bhutan, Sikkim); P. cooperi Noltie (Sikkim); P. longii Noltie (Sikkim); P. lachenensis Noltie (Sikkim); P. rajbhandarii Noltie (India, Nepal, Bhutan). Poa himalayana Nees ex Steud. has been misunderstood and a new lectotype is chosen, replacing that of Bor; P. stewartii Bor is reduced to its synonymy.

Three new species and one new subspecies of Stipa are described from the E Himalaya: S. jacquemontii subsp. chuzomica and S. bhutanica which appear to be endemic to Bhutan: S. milleri from Nepal, India (Sikkim) and Bhutan and S. rohmooiana from India (Sikkim).

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.
