Abstract

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.
