- Diagnosis
- Flowers bisexual, with an enlarged cupulate receptacle bearing imbricate bracts (or perianth). Vascular tissue of pedicels with vessels with
scalariform perforation plates. Inner surface of receptacle glabrous, smooth. Bracts auriculate. Several imbricate tepals borne on rim of cupule. Stamens (presumably) attached near rim of receptacle, laminar, fleshy, incurved.
Anthers tetrathecal, adaxially embedded, opening by longitudinal
valves. Pollen spheroidal without well-defined apertures, but with sulcoid areas, exine tectate columellate, reticulate. Pistillodes (?) present to outside of carpels. Carpels free, usually about five, attached to the base of the cupulate receptacle; lacking associated trichomes, stigmas bilobed, not peltate, not contiguous. Seeds more than six, in two marginal rows, distally winged, with a proximal flange or aril.
