2 According to Foreman (I.e.) this species is, although restricted in its distribution, locally quite common. In the Mt Piora area the seeds of M. womersleyi are used as a bait in kapul (possum) traps. The seeds also are a possible source of spice and oil, as already noted by Sinclair, I.e. 1 Resembles M.fusca and M. sphaerosperma in general habit and inflorescences, taxonomically closest related to the latter. Myristica fusca is distinguishable by the papillose lower leaf surface; M. sphaerosperma differs e.g. in the irregularly papillose lower leaf surface and a longer fruiting pedicel (7-15 mm). Myristica womersleyi also resembles M. chrysophylla with similar leaves, but that species has different fruits, 2-4.5 cm long, with 2-5 mm long yellow brown hairs.
