Five to seven vascular bundles are present in the outer fruit wall marked by narrow ribs extending from the base of the fruit to the base of the perianth. Surface of the fruit characterized by small circular grooves arranged in longitudinal furrows between the vascular bundles, giving the fruit wall a foveolate appearance. Fruit apparently a drupe with a thin fleshy outer layer. Epidermis cells with bulging periclinal walls covered by a thick wrinkled cuticle. Apically epidermis cells form distinct elongated verrucae. Minute trichomes occur in the longitudinal grooves.
