Description
Distribution
Ecology
It is a nitrogen-fixing legume.[1] In a study by Davis, it was discovered that C. rotundifolia had higher mortality and less biomass in high carbon dioxide plots, suggesting that not all species will perform well as global carbon dioxide levels rise.[2]
Habitat
It’s a common associate in longleaf pine savannas.[2] It can also be found in sandhill communities.[3]
Phenology
It has a broad, bimodal flowering phenology with peaks in early April and late fall.[4] Perennial herbaceous legume.[2]
Seed dispersal
Seeds are forcefully expelled after the fruit matures and dries, and ants act as the main dispersal agents. The ballistic dispersal distance was found to be around .94 meters.[3]
Seed bank and germination
Fire ecology
Its reproduction is robust to burn treatments and season of burn.[4]
Pollination
Use by animals
Caterpillars are often found consuming C. rotundifolia. Ants, especially Pogonomyrmex badius, help disperse the seeds long distances.[3]
Diseases and parasites
Conservation and Management
Cultivation and restoration
