- Diagnosis
- Flowers bisexual, with an enlarged cup-shaped receptacle bearing imbricate bracts (or perianth). Vascular tissue of pedicels with vessels with
scalariform perforation plates. Inner surface of receptacle glabrous, striate. Bracts auriculate. Stamens (presumably) attached to rim or receptacle, laminar, fleshy. Anthers tetrathecal, embedded, opening by longitudinal valves. Pollen monosulcate, exine apparently solid with microchannels.
Carpels free, numerous, attached to the base of the cupulate receptacle; stigmas peltate, contiguous, forming a platform in the receptacular chamber. Seeds six or more in two marginal rows, distally winged, with a proximal flange or aril.
