Fimbristylis thermalis grows in alkaline mud and sand, especially around hot springs and mineral-rich seeps.

At the top of the stem is an inflorescence of ovate, pointed spikelets, each on a long peduncle. The spikelet has many hairy bracts. The fruit is a shiny brown achene one to two millimeters long.[4][5]
