Original diagnosis/description

Flower structurally bisexual, with multiparted perianth, androecium and gynoecium. Floral receptacle flat to slightly concave but conical in the pistillate region. Phyllotaxis of floral organs apparently spiral. Perianth of about 50 tepals in several series. Tepals broad with transversely elongate and rhomboidal bases. Androecium of more than 50 stamens in several series. Stamens with short bases, poorly differentiated from the anther, rhomboidal in transverse section. Anthers dithecate and tetrasporangiate with an expanded and slightly pointed connective apex. Pollen sacs in a lateral position. Gynoecium superior, apocarpous, of more than 50 free carpels borne in several series on the conical gynoecial portion of the receptacle.
