Morphology General Habit
Lianes or climbing shrubs (or small trees but not in Africa)
Morphology General Tendrils
Tendrils absent
Morphology Branches
Branchlets often zig-zag
Morphology Leaves
Leaves alternate, petiolate; blades serrulate or crenulate or nearly entire, elliptic or more elongate, usually rounded at base, acute, acuminate or obtuse, penninerved with the tertiary nerves often rather elegantly percurrent
Morphology Leaves Stipules
Stipules minute, subulate, caducous
Morphology Reproductive morphology Flowers
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
Morphology Reproductive morphology Flowers Calyx
Sepals deltoid
Morphology Reproductive morphology Flowers Corolla
Petals usually clawed and the body concave, cucullate (or absent but not in African species)
Morphology Reproductive morphology Flowers Disc
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)
Morphology Reproductive morphology Flowers Gynoecium Ovary
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
Morphology Reproductive morphology Fruits
Fruit dry, samara-like, with a basal 1-celled thinly double-walled nearly spherical body, a single small seed and an elongate terminal wing.
