Abstract

Garcinia sections Dicrananthera and Macrostigma (Clusiaceae) is revised for Thailand. Three species are enumerated, i.e., one species, G. thorelii belongs to the section Dicrananthera, and two species, G. nuntasaenii and G. prainiana, are in the section Macrostigma. Detailed morphological descriptions and illustrations are provided, together with notes on distribution, habitats and ecology, phenology, conservation assessments, etymology, vernacular names, uses, and specimens examined. An identification key to the species of section Macrostigma is presented. One name, G. thorelii, is lectotypified here. For Garcinia nuntasaenii we recommend a conservation status of Endangered [EN B2ab(v)] and for the other two species (G. prainiana and G. thorelii) a conservation status of Least concern [LC]. A number of vegetative characters and features of reproductive organs, especially the flowers, distinguish the two sections and we enumerate these herein.
