Tree to 25 or 30 m tall and 1 m d.b.h., the bark narrowly vertically fissured with corky ridges, dark gray to blackish; wood superficially similar to oak, of medium density, light grayish brown with distinct pattern from stripings of brown paratracheal parenchyma, when fresh with faint sweet odor suggesting watermelon; twigs subtetragonal, lepidote, with thick pith, the nodes without interpetiolar glands or pseudostipules. Leaves palmately 5-foliolate, often aniso-phyllous; the leaflets elliptic to elliptic-oblong, acute to acuminate, basally rounded to cuneate, the terminal leaflet 8-35 cm long and 3-18 cm wide, the intermediate pair 6-34 cm long and 3-17 cm wide, the lateral pair 3.5-25 cm long and 1.4-12 cm wide, entire, subcoriaceous to chartaceous, lepidote above and beneath, gray-green when dry; the terminal petiolule 2-11 cm long, inter-
A large tree. The bark is grey and has furrows. The leaves are compound with leaflets spread like fingers on hand. There are 5 leaflets. The flowers are pink. They are produced before the leaves.
It is a tropical plant. It grows in wet, moist and dry forests. It grows from sea level to 1,200 m above sea level. It grows in areas with a temperature range between 20°-30° C. It grows in areas with a rainfall above 500 mm.
