Philydraceae is a family of flowering plants composed of three genera and a total of six known species.[3] Such a family has not been recognized by many taxonomists.

The APG II system, of 2003 (unchanged from the APG system, of 1998), does recognize such a family and places it in the order Commelinales, in the clade commelinids, in the monocots. It consists of only very few species of perennial, tropical plants in Southeast Asia and Australia.
Helmholtzia glaberrima
