Abstract

Deciduous, aromatic tree; branches densely lenticellate. Young branches and leaves covered with simple hairs and aromatic, resinous, peltate, basally embedded gland-scales. Leaves alternate, stipulate, imparipinnate. Inflorescences slender, nodding, panicles, clustered in the axils of distal leaves and bracts; flowers in dichasial triplets, the central flower of each triplet perfect and fertile, the lateral ones pistillate, reduced, sterile or abortive. Flowers small, inconspicuous; tepals of the perfect flowers 2 + 2, small, persistent on the fruit; disk wanting; stamens 6; filaments short; anthers basifixed, dithecal, tetrasporan-giate, opening by longitudinal slits. Ovary superior, bicarpellate, bilocular below, unilocular above; stigmas 2, free, lamelliform, carinal; ovule solitary, attached to the septum in one locule, hemitropous to anatropous, bitegmic, crassinucellar. Fruit a two-winged nut; seed solitary, without endosperm; embryo straight, oily, with 2 thick cotyledons.
