2 Myristica lowiana is related to M. maingayi which differs in less stout twigs, less coriaceous leaves, slightly larger flowers with less thickly pubescent androphore, and less thickly tomentose fruits; apparently M. lowiana is largely confined to forest on poorer soils, like swamp forest, kerangas, and ridge forest. 1 Usually the nerves are clearly sunken above, but in some specimens from the East Coast of Sumatra, Bangka, and many from Borneo, (in older leaves) they may be raised above. 3 Variation mainly concerns the thickness of the indumentum of the fruits, especially in Borneo, where it may vary between 1 and 3 mm; in S 16509 the hairs are dense and shaggy, 2-3 mm long. In Sumatran and Malayan specimens the hairs are shorter, 1-2 mm. FRI 7734 (Cockburn) from Peninsular Malaysia (G. Panti) deviates from other Malayan material by its stout habit, rather small fruits (6 cm) with very thick fur-like indumentum, hairs 3-4 mm long; possibly this specimen represents a separate variety.
