Taxonomy

1 According to Foreman (1978) this is the Myristica with the largest fruits in New Guinea. It is distinguishable by the stout habit of all parts, the large leathery flowers, the large fruits with thick pericarp, and the aril-lobes only covering the basal part of the seed. 2 Myristica ingens is the only species in the genus Myristica with a reduced aril; in all other species the laciniae of the aril cover the seed over its entire length.
