A large tree. It can grow up to 35 m high and be 1 m through in the trunk. The leaves have 3-5 pairs of opposite leaflets and a leaflet at the end. The leaflets are long or oval and 7-25 cm long by 4-8 cm wide. The leaflets are pointed at the tip and wedge shaped at the base. At the base of the leaf stalk there is a round leafy structure called a stipule. It can be 8 mm across and softly hairy. The small branches are 4-6 mm thick. The flowers are fairly small and borne in large compound flower clusters. The flower clusters occur in the axils of leaves. The male clusters are 10-25 cm long while the female clusters are 5-18 cm long. There are many male flowers in the cluster but 3-5 female flowers in the female clusters. The fruiting stalk can be 4-10 cm long. The fruit is oval and slightly triangular in cross section. Fruit are 2-4 cm long by 1-2 cm wide.
Uses. The timber, which is not very hard, is sometimes used. This tree is the principal source of manila-elemi (see W. H. BROWN Min. Prod. Philip. For. 2 1921 40 VALENZUELA et al. Philip. J. For. 6 1949 54 MANALO & WEST Philip. J. Sc. 78 1950 111 Quis. Med. Pl. Philip. 1951 475 ). The seeds are eaten as pili nuts, though the Main source of these is C. ovatum Engl.
