The inflorescence is a raceme of flowers with oval white petals that narrow near the yellowish bases and measure just over a centimeter long.

It is limited to a part of the Piney Woods region on the Gulf Coastal Plain where there is alkaline soil derived from the Weches Formation.

[3][5] This geologic formation contains carbonates above a layer of water-impermeable glauconite, which keeps the soil above from draining, leaving the area quite moist.

[4] Other rare plants that occur on the Weches Formation include Sedum pulchellum, Calylophus drummondianus, Liatris mucronata, Paronychia virginica, Petalostemum pulcherrimum, Heliotropium tenellum, Eleocharis compressa, and Cuphea viscosissima.

[6] Habitat conservation activities include the removal of brush and vegetation buildup by mechanical means or with herbicides or fire.
