Thurniaceae

The Thurniaceae are a family of flowering plants composed of two genera with four species. The botanical name has been recognized by most taxonomists.

Prionium serratum, the palmiet, is a robust, evergreen, semiaquatic, rhizomatous flowering plant growing to in height. It is the only species in the genus Prionium, and is endemic to South Africa (Cape Province and KwaZulu-Natal). Some authors have separated Prionium from the Thurniaceae, putting it instead in its own family, the Prioniaceae.

Thurnia is a group of herbaceous plants described as a genus in 1883.
