Taxonomy
Poupartia mangifera Bl. 1826 is an illegitimate name as BLUME cited three earlier names in synonymy, viz Mangifera pinnata L.f. (1781), Spondias mangifera WILLD. (1799) and Spondias amara LAMK (1796), which all refer to Spondias pinnata (L.f.) KURZ. In 1850 BLUME removed these synonyms and named the species Dracontornelon mangiferum Bl., but again mentioned under this name an older synonym (Pou-partia pinnata BLANCO, 1837) making the combination illegitimate.
Uses
The timber is rather soft, rather light to moderately heavy, little durable. The sapwood is pale and subject to insect attack. The heartwood varies considerably from greyish brown, usually with dark grey to black bands, to almost black. Boles have a mean maximum branch-free height of 25 m, a mean maximum d.b.h. of 80-100 cm, but they are usually heavily buttressed. The timber is in demand for matched sliced veneers, but also suitable for rotary veneers; also suitable for panelling, furniture, quality cabinet work, flooring, boxes, matches. Trade names: sengkuang (Malaysia), paldao (Philippines), dar (West New Guinea), New Guinea Walnut (Papua New Guinea).
A handsome and ornamental tree which could be used effectively for avenues.
The fruit is inferior and sought mostly by children. Flowers and leaves may also be eaten as a vegetable (CORNER l.c.). The bark is possibly of medicinal value (BURKILL).
