Taxonomy

1 Myristica sulcata is recognized by its sulcate or angled twigs, especially the apical part, and the on drying conspicuously (dark) brown, seemingly glabrous leaves. 3 Myristica sulcata may be confused with M. crassipes and M. flosculosa, two species generally with rather angular twigs and somewhat resembling leaves. 2 Jacobs 9685 and LAE 52028 (Morobe Prov.) are mutually similar; they deviate from M. sulcata by their faintly angled twigs and ellipsoid (not subglobose) fruits with broadly rounded apex and asymmetrically positioned stigma remnant. Possibly these specimens represent a separate form within M. sulcata. The fruits of these specimens have some reminiscence to those of the related M. undulatifolia.
