Taxonomy

Myristica tubiflora is a lowland species, characterized by leaves of a small size class, sessile inflorescences, elongate male flowers with long pedicels, with the (sub)persistent bracteole usually at some distance below the perianth (in most Myristica species the bracteole is apical) and elongate fruits. Sterile specimens and those with immature fruits may resemble M. lepidota subsp. montanoides, and some, now treated under M. tubiflora, may belong to that taxon or vice versa. This may partly account for the remarkable variation in leaf texture admitted for M. tubiflora: the majority of the specimens have subcoriaceous leaves, but some have brittle membranous leaves, with a more distinct venation, reminiscent of the leaves of M. lepidota subsp. montanoides. The latter subspecies, however, is distinguishable by its small flowers and fruits.
