Abstract

Mangiferasumatrana Miq. is an endemic species from Sumatra. The taxonomic status of M.sumatrana remains unclear and is currently treated as a synonym of M.laurina. The present study employed morphological and palynological characters and molecular analyses to address the delimitation between the two species. Pollen observations were carried out with a Scanning Electron Microscope (SEM). Phylogenetic relationships were investigated using the ITS and the trnl-F intergenic spacer markers. M.sumatrana differs from M.laurina by having pyramidal panicles with a low density of pale yellow flowers pale, sepals 3-3.5 × 1.7-2 mm, fruit roundish to flattened with pale yellow pulp, a rough fibre texture, and pollen with a prolate spheroidal shape. The MP phylogenetic tree showed a divergent boundary between the two species suggesting that M.sumatrana could be an independent species, not a variety of M.laurina. The present study supports the view that these two taxa can be treated as different species.
