whorl near the margin of disc (expanded torus); filaments free, filiform; anthers short, oblong or linear, basifixed; connective produced apically; pollen 3-colpate. Carpels 8 -
20 or rarely less, in a single whorl, free or loosely united at base, flattened with papyraceous wings, obovate or oblong, not completely closed; stigma sessile, as a crest, lateral on upper side of carpel opposite to the insertion of ovules.
