The moonseed family (Menispermaceae) consists mainly of vines, rare shrubs or trees with unisexual flowers, and drupaceous fruits. Up to now, six species and three unidentified species in morphogenus Palaeosinomenium have been reported. However, more fossil evidence is required to detect the morphological evolution between the morphogenus and the living genera.
