Description

Xenofructus is distinguished by a fruit or ovary borne on a short stalk, exhibiting a straight abaxial surface and a convex adaxial surface. A pronounced ridge is present along the abaxial side. The placenta is not attached to either the abaxial or adaxial margins of the fruit or ovary. Ovules are enclosed within the fruit or ovary, occurring in clustered arrangements and possessing a sickle-like shape.^[1]
