Diagnosis
Fruit consisting of a persistent pedicellate hypogynous five-lobed calyx with a thickened central disk supporting one or occasionally two globose to ellipsoidal fruit bodies. Early stages in fruit formation showing one or two whorls of five apocarpous ovaries near the margin of the floral disk. Each carpel with a single style. Corolla and stamens unknown. Calyx widely concave, lobes entire margined, equal to subequal, elliptical to obovate, apices rounded; sinuses between lobes of calyx acute, deeply incised. Venation of calyx lobes consisting usually of five main longitudinal veins; the midvein slightly stronger, the outer pairs successively weaker, all arising independently from the base, sometimes dichotomizing in course to apex. Secondary veins arising from the longitudinal veins at acute angles, commonly meeting those from adjacent longitudinal veins to form distally arching cross veins and forming loops at the margin. Cuticle of calyx, when preserved, showing abaxial lower epidermis with elongate epidermal cells and longitudinally aligned sunken stomata.
