Description

Triphysaria versicolor is an annual herb producing a green or yellowish stem up to about 60 centimeters in maximum height. Like many species in its family it is a facultative root parasite on other plants, attaching to their roots via haustoria to tap nutrients. The leaves are up to 8 centimeters long and are divided into a few narrow, pointed lobes.

The inflorescence is a dense spike of flowers. Each flower has a white corolla 1 or 2 centimeters long with a beaklike, yellow-tinged upper lip and a wider lower lip which is divided into three pouches. The lower lip may have purple spots underneath.
