1 Strange enough, of this apparently fairly common tree, only Scortechini 1949, and one recent collection (Borneo), bear well-developed male flowers. Female flowers have never been collected. 2 Variable in length of the hairs on the sterile leaf bud, either 0.1-0.2 mm only or up to 2 mm long; because of this, M. gigantea appears twice in the keys. Whether this difference has taxonomic implications is not known. 3 Related to M. maingayi, but with smaller inflorescences, flowers and fruits. It reaches a large size as a tree, and is known as the tallest Malayan Myristica. Myristica maingayi has a lower stature, stouter twigs, larger leaves with acute apex, larger male inflorescences and flowers, androecium with sterile apex, and slightly longer glabrescent fruits.
