Syzygium ngheanense (Myrtaceae: Myrtoideae), a new species of Syzygium from Central Vietnam

Abstract

Syzygium ngheanense (Myrtaceae), a new species from Nghe An Province, in Central Vietnam is described and illustrated. The species is most similar to S. vestitum, S. scarbum and S. levinei but differs from the three latter in having glabrous bracts and bracteoles, sparsely scabrid flower buds and hypanthia, larger sepals and petals, longer stamens and styles. Information on phenology, ecology and distribution is provided, together with a preliminary conservation status assessment and taxonomic notes for the new species and a key to distinguish it from three hairy Syzygium species in Indochina.
