Notes
This species is very close to S. robin- sonii, but has slightly smaller flowers, usually a deeper divided calyx, and the pods have stronger raised margins. The pollen of the two species is very similar too. Serianthes hooglandii has polyads 110-120 pm in diameter, S. robinsonii polyads 140 pm in diameter (Guinet in Nielsen, Guinet & Baretta-Kuipers, l.c.). Serianthes robinsonii and S. hooglandii with its two subspecies could also be considered as three replacing subspecies, in the Moluccas, New Guinea, and the Solomons.
