Description
This is an annual herb growing erect 10 to 40 centimeters tall. It is mostly hairless except for the sepals, which have some rough hairs. The leaves are located along the stem and measure 4 to 9 centimeters long. The inflorescence is made up of paired branches bearing several five-lobed white flowers each about half a centimeter wide. The fruit is a ribbed nutlet 1 or 2 millimeters long.
Range & habitat
It grows in wet grassy habitat kept moist by runoff from hot springs and pools. The combined area of land containing the two populations was estimated to be less than 80 square meters in 1990. The species is threatened by the disturbance of its grassland habitat; both populations are on privately owned, unprotected land; one of these is situated next to a small airport.
