Monoecious tree. Leaves distichous, penninerved, with infrequent laticifers. Racemes corymbiform, short. Calyx in anthesis small, patelliform, shortly 4-dented, much accrescent afterwards to form a frill which includes the fruit below. Petals 4 in the ♂, 6-8 in the ♀, connate to an urceolate tube for the lower ¾, free above in form of 4 lobes. Disk extra-staminal, annular, crenulate, thin, finally disappearing. ♂ Flowers: Stamens 4, epipetalous; filaments fused to a tube which bears the free anthers on top; connective thick. Ovary rudimentary. ♀ Flowers: Staminodial tube without anthers. Ovary pyramidal, 1-celled, with 2 (unitegmic or naked?) ovules pendent from the short basal placenta; style short-conical; stigmas 3, sessile. Fruit drupaceous, concrescent with the much enlarged calyx below; pericarp fleshy; endocarp thin-woody. Seed 1, containing exclusively oil; embryo excentrically at apex of endosperm.
