Abstract
Living collections of botanic garden have been one of reliable reference in species determination. Bogor Botanic Gardens^ (BBG) 2019 database recorded about 25% of Sapotaceae collection were identified to genus or family level only. Furthermore some specimens may have incorrect identity due to complexity of vegetative character or reproductive characters which is not always available. Identification of a historical and economical important species, Palaquium gutta, has a long problematic due to its complex morphology until now. A field morphological observation led the possibility of misidentification of a BBG specimen of ^Palaquium gutta^. By employing the ITS region and generating a phylogenetic tree, we revealed the true identity of the specimen. The DNA barcoding is a powerful method in supporting conventional morphological assessment, particularly reidentification or confirming a Palaquium gutta spesimen of Bogor Botanic Gardens.
