Description
Triphysaria floribunda is an annual herb producing a hairy to hairless yellow-brown stem up to about 30 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. Its greenish leaves are up to 4 centimeters long and are divided into several narrow, pointed lobes. The inflorescence is a spike of flowers a few centimeters in length. Each flower has a narrow greenish upper lip and a wide lower lip which is divided into yellowish or white pouches.
