DIOSCOREACEAE

Dioscoreaceae is a family of twining shrubs or herbs belonging to the Monocotyledonous group, but resembling the Dicotyledons in many superficial characters, the leaves being decidedly stalked and having netted veins. The family is a small one, and with the exception of one genus (Tamus) confined to the tropics. The family includes the Yam.
