New Aglaonema (Araceae) of Thailand

Abstract

Aglaonema chermsiriwattanae is a new species in section Chamaecaulon which was collected from peninsular Thailand. The species is distinguished by its repent stem, cataphyll subtending peduncle, spathe ovate and opening towards apex, and peduncle longer than petiole. This species differs from Aglaonema brevispathum, A. costatum in characteristics of the petiole cataphyll, and differs from A. pumilum in characteristics of the spathe, anther dehiscence and stem cataphyll.
