Taxonomy

Horsfieldia obtusa obviously belongs in the group of species with H. polyspherula on account of the articulated pedicel and angular androecium with the distally free anthers. The species is distinguishable by generally flat nerves and rather large male flowers with 18 or 20 thecae. By the rather small coriaceous leaves with rounded apex it is reminiscent of H. montana which has quite different male flowers. Horsfieldia xanthina has similar large, pale yellowish hair scars on the leaves, but differs in other ways.
