Characteristics

Large woody climbers. Branchlets frequently lenticellate; bud scales or bud scale scars present at base of new growth. Leaves opposite; colleters present in the axils. Inflorescence a terminal panicle; flowers 5-merous. Sepals often connate for large part of length; colleters in a row inside. Corolla lobes dextrorse and twisted to the left in bud; tube distinctly widening at point of stamen insertion, lobes obovate, slightly asymmetrical; salverform in mature flower. Stamens inserted in lower half of corolla tube, completely included in tube; filaments short; anthers fertile in the upper half only, the lower half sterile, laterally with lignified guide rails and sagittate appendages at the base; adnate to the style head. Disk entire, 5-dentate; shorter than the ovaries; glabrous. Gynoecium 2-carpellate, apocarpous but apically united into a common style, often somewhat semi-inferior; ovules numerous; ovaries glabrous. Fruit of paired follicles, mostly rather flattened, rarely fused together at the apices. Seeds with a long narrowly acuminate end topped with a coma directed towards the fruit apex.
