Abstract

Two new species of Polyalthia from Peninsular Thailand, Polyalthia heliopetala and P. taweensis, are described and illustrated. Polyalthia heliopetala most closely resembles P. oblonga and P. motleyana. Polyalthia taweensis most closely resembles P. obliqua. Polyalthia pumila is newly reported for Thailand from a single locality; the species was previously known only from two localities in Peninsular Malaysia and has not been re-collected in over 100 years.
