Sphenoclea is a genus of succulent erect annual herbs. They occur in damp habitats throughout the tropics.

There are two species,[1] S. zeylanica and S. pongatium. The genus is placed alone in family Sphenocleaceae. The position of the family is somewhat uncertain; it is now usually placed in Solanales, but it has previously been placed in Asterales, especially near Campanulaceae, and there is some evidence to support this.
