Capsules subglobose, 5–7 mm. Seeds 3–3.5 mm, outer 2 margins winged, wings 0.1–0.2 mm wide, striate, undulating.

Jacquemontia curtissii is endemic to southern Florida, especially to rocky pinelands over limestone in the Everglades, also marl prairies, mesic flatwoods, and disturbed uplands. Stout rootstocks enable J. curtissii plants to survive fires.
