Taxonomy
1 Myristica corticata is closely allied to the variable M. iners; both have the same smooth, non-papillose structure of the lower leaf surface (lens!), which is of almost the same colour as the upper surface. Myristica corticata may be confused with stout specimens of M. iners from northeastern Borneo. The differences between these species have been discussed in detail by De Wilde (I.e.: 158).
2 In M. corticata the distinct marginal arches of the leaf venation are like those of certain forms of M. extensa andM. malaccensis, and the stout twigs with conspicuously cracking bark are like those of M. papyracea (but here the lower leaf surface is strongly papillose).
