Abstract

This paper presents a re-evaluation of the taxonomic identities of Lecanorchis trachycaula and L. betung-kerihunensis. Consequently, L. trachycaula is reduced to a synonym of L. purpurea while L. betung-kerihunensis is treated as a synonym of L. malaccensis. Because no original material of L. purpurea is existent, we designate its neotype to stabilize its taxonomic status.
