Leaves membranous, elliptic-oblong, ll-20(-26, see note 2) by 3-7.5(-9) cm, apex for 1-1.5 cm acute-acuminate. Fruits short-ellipsoid, 1.5-2 by 1.1-1.5 cm including pseudostalk up to 2.5 mm long.
Asia-Tropical: New Guinea present, Bird's Head, near Manokwari present, Papua New Guinea present, W Papua Barat present
Malesia: New Guinea (possibly W Papua Barat: Bird's Head, near Manokwari, cf. De Wilde, I.e.: 106; Papua New Guinea).
2 Sands et al 6165, from Bird's Head, with leaves to 26 by 9 cm and fruits 2 by 1,5 cm, is like a giant form Of var. calcarea; its twigs measure 4(-5) mm in diameter at the apex. Possibly it should be recognized as still another, new variety. 1 The male flowers are stouter and have a thicker perianth as compared with those of var. subtilis. The inflorescences are 8-9 cm long, stouter than generally found in the type variety.
