AbstractBackground – Coffea malayana, the only species described under that genus in the Malay Peninsula, is re-assessed with syntypes found in the Singapore Herbarium. Methods – This study is based on herbarium material. Conventional herbarium techniques were applied for taxonomy. The IUCN conservation status was assessed using GeoCAT. Results – Coffea malayana is congeneric with Prismatomeris . The name is lectotypified but its potential combination as Prismatomeris is pre-empted by the validly published binomial Prismatomeris malayana for a different taxon. Therefore, Prismatomeris khoonmengiana is proposed as a new name for Coffea malayana .
