Myristica guatteriifolia A.Dc.

Tree 10-25 m. Twigs 3-5(-10) mm diameter, hairs rust-coloured, 0.2-0.5 mm; older twigs glabrescent, smooth or rarely flaking, usually without lenticels. Leaves chartaceous, elliptic-oblong to oblong-lanceolate, (12-) 15-35 by 3-12 cm, base rounded or attenuate, apex acute-acuminate; upper surface olivaceous (-brown), lower surface grey-brown or cinnamon, pubescent or late glabrescent, hairs dense, 0.2-0.3 mm, with scattered émergents 0.5(-2) mm; not papillose; dots absent; midrib ± raised above, lateral nerves 15—19(—25) per side, at about 45° to the midrib, flat or slightly sunken, lines of interarching and venation distinct or faint; petiole 15-30 by 2-4 mm; leaf bud 10-20 by 2.5-4 mm, hairs 0.2-1 mm. Inflorescences paniculate, between the leaves or sometimes axillary to reduced leaves in short-shoots, with dense hairs 0.2-0.6 mm; bracts caducous, 2 mm long; in male: 2-8 cm long, once or twice branched, peduncle (0-)4-20 mm, flowers in clusters of (1—)2—10, buds of variable sizes; female inflorescences similar but shorter and fewer flowered, simple or little-branched, 0.5-2 by 0.5-1 cm, peduncle to 7 mm; flowers with hairs 0.3-0.6 mm. Male flowers: pedicel 3-6 mm, bracteole (2-)2.5-3 mm, caducous; buds ovoid or ellipsoid, (4-)5-7 by 3.5-5 mm, cleft 1/4-1/3, lobes 0.3-0.5 mm thick. Androecium 3-5 mm; androphore 1.5-2 mm long, the basal (l/2-)2/3-3/4 with pale hairs 0.4-0.7 mm; synandrium 2-3 by 0.8-1.8 mm, thecae 16-24, sterile apex up to 0.2 mm, glabrous or rarely with few hairs 0.2-0.3 mm, or apex of synandrium ± truncate, rounded, or to 0.3 mm hollowed. Female flowers: pedicel l-2(-4) mm long; buds broadly ovoid, 4-6 by 3.5-6 mm; ovary broadly ovoid, 2.5-3.5 mm diameter, hairs dense, 0.5 mm long, stigma lobes oblique, faintly lobulate or not. Fruits up to 3 per infructescence (sometimes seemingly more-fruited when infructescences are ± clustered), short ellipsoid or subglobose, 2.5-4(-4.5) by (2-)2.5-3 cm, hairs dense, velvety or shaggy, 0.5-1 (-2) mm; pericarp 3-5(-8) mm thick (not woody); seeds 2-2.5(-3) cm long; fruiting pedicel 1.5-5 mm long.

Frequently found in evergreen to deciduous coastal forest/vegetation but also sometimes in forests further inland; on various types of soils, including sandstone and limestone derived and ultrabasic soils; at elevations up to 400 metres.

Can be grown by seedlings.
