Abstract

A new species, Quercussontraensis Ngoc, Binh & Son is described from Son Tra Nature Reserve, Son Tra Peninsula, Central Vietnam. We examined the morphology and constructed a highly resolved phylogeny of Q.sontraensis and its relatives (including Q.langbianensis and Q.cambodiensis) using Multiplex ISSR genotyping by sequencing (MIG-seq). The morphological analyses and molecular evidence support the distinction between the new species (Q.sontraensis) and its relatives.

Keywords: Da Nang City; MIG-seq; flora; phylogeny; taxonomy.
