Lectotypifications of Three Names in Garcinia, Synonymy of Garcinia pedunculata and Detailed Descriptions of Three Species in Garcinia Section Brindonia (Clusiaceae)

A revision of the genus Garcinia has recently been undertaken by the author as part of the Flora of Thailand. Herbarium specimens deposited in several herbaria, and those included in the digital herbarium databases, were examined by consulting taxonomic literature. In this study, the three names in Garcinia section Brindonia are lectotypified as G. gracilis, G. lanceifolia and G. planchonii. A new synonym for G. pedunculata, namely G. planchonii, is proposed. Detailed descriptions, recognitions and illustrations of three species in Garcinia (G. atroviridis, G. lanceifolia and G. pedunculata) are presented, along with information on distributions, specimens examined, habitats and ecology, IUCN conservation status, phenology, etymology, vernacular names and uses. The fruits, the young shoots and leaves, and the flowers of these three species are edible and have a sour taste. These species are often cultivated for their fruits.
