General Information

Climbing shrubs or lianas, rarely small trees. Leaves alternate, leathery or nearly so, rarely papery, conspicuously reticulate, base asymmetric, margin entire or toothed. Flowers small, bisexual, 5-merous, few in fascicles or in shortly pedunculate cymes, or in terminal or axillary, cymose panicles. Sepals 5, triangular, adaxially medially keeled. Petals obovate-orbicular, apex emarginate, rarely absent. Disk thick, fleshy, pentagonous. Ovary globose, immersed in disk, 2-loculed, with 1 ovule per locule; styles 2-fid. Fruit a 1-seeded, indehiscent samara, 1/3-1/2 of base surrounded by persistent calyx tube, apex with longitudinally elongating oblong wing, with relict styles; endocarp globose, thin, woody, 1-loculed, 1-seeded. Seeds without endosperm; cotyledon thick.

    Flowers 5-merous, perfect, half-epigynous, usually in very densely crowded divaricate axillary cymes (these so condensed as to appear like nodal glomerules), or sometimes the leaves so reduced and the upper branches so crowded that these smaller inflorescences are borne in thyrses or panicles, or very rarely the flowers solitary in the axils

    Ovary 2-celled (but only 1 cell fertile), half-inferior, the superior moiety (or perhaps better called the style) expanding to hundreds of times its anthetic size in the form of an elongate terminal strap-like wing the plane of which bisects the 2 original ovary cells and which at the tip carries the 2 minute persistent styles

    Disk thick, adnate to the lower (fertile) half of the ovary, later somewhat accrescent and along with the cup fused to the basal sixth to half of the fruit-body (not the wing)
