Abstract
Two new Friesodielsia species (Annonaceae) from Peninsular Thailand, F. betongensis and F. chalermgliniana, are described and illustrated. The addition of these raises the total number of Friesodielsia species in Thailand to 18. A conservation assessment for each new species and an identification key for all Thai species are provided.
