Inflorescences rather condensed, much branched, 6-15 cm long, the flowers densely rusty pubescent, hairs 0.2-0.5 mm long. Fruits fusiform, ellipsoid, ± obovoid, or pear-shaped, 1.7-3.5 by 1.2-1.9 cm, apex acute to broadly rounded, base rounded or narrowed;

Malesia: Moluccas (Talaud, Morotai, Halmahera, Bacan, Obi, Buru, Seram, Ambon); possibly Sulawesi (sterile coll.) and Philippines (NE Luzon); see notes.
2 Ridsdale c. s. ISU 317, from Palanan, NE Luzon, strongly deviates in its very hairy appearance, and may represent a separate taxon. 1 Subsp. macrocoma is arbitrarily separated from subsp. prainii, the latter being very variable in many features, and mainly differing by a much less developed indumentum on leaf buds and inflorescences, and by its generally larger fruits. Subsp. macrocoma has a remarkable variation in fruit shapes. Its fruits are generally ± ellipsoid, but fruits from Bacan and Obi are small, 1.7-2.2 cm long and either broad-ellipsoid or obovoid; in Buru fusiform fruits 28 mm long are found.
