Taxonomic treatment of three Thai Garcinia species (section Brindonia, Clusiaceae), with six lectotypifications and conservation status assessments

The taxonomy of three Garcinia species — G. bancana, G. costata, and G. parvifolia (section Brindonia, Clusiaceae) — is revised for Thailand. Morphological descriptions, illustrations, and photographs are provided, along with notes on distribution, phenology, conservation status, etymology, vernacular names, uses, specimens examined, habitats, and ecology. All three species are restricted to Peninsular Thailand and produce edible fruits.

Six names are lectotypified here, including G. bancana and its three synonyms (G. lamponga, G. leucandra, and G. oxyedra), as well as G. parvifolia and its synonym (G. globulosa). Garcinia costata is assessed as Vulnerable (VU) under IUCN criterion D 1, whereas G. bancana and G. parvifolia are assessed as Least Concern (LC).
