Description
Chamaecrista nictitans is a decumbent herb that forms large mats.
Distribution
Ecology
It is a legume. By mid-season in June and July, a maximum nitrogen-fixing rate was observed.[1]
Habitat
C. nictitans is tolerant of overstory canopies that decrease the light level to about half the ambient (i.e., it can live in partially shaded areas and its nitrogen-fixing capability won't be significantly affected).[1] It is also tolerant of a wide range of dry to wet soil types, having been found in soils as diverse as sandy silt loam, low black sandy peat, shallow soil overlaying limerock, shell sand, red clay, loessial soil, sandy clay loam, dry marl, calcareous and shaly soils, clay, igneous intrusive rocky soils, and novaculite ridges (FSU Herbarium).
C. nictitans occurs in a variety of natural and disturbed communities. It is found in longleaf pine-wiregrass communities,[1] longleaf pine-scrub oak sandy ridges, annually burned savannas, xeric oak-saw palmetto scrub communities, wooded banks of creeks, slash pine flats, borders of brackish and salt marshes, low weedy swales, laurel oak woodlands, upland slopes, dry sandhills, margins of hillside bogs, and loblolly pine forests (FSU Herbarium). C. nictitans is also able to colonize some disturbed areas, including roadsides, railways, clear-cut pine flatwoods, vacant lots, cultivated fields, power line corridors, old fields, and plantations of young slash pine (FSU Herbarium).
Associated species include Chamaecrista fasciculata, Panicum, Andropogon, Strophostyles leiosperma, oaks, saw palmetto, broomsede, laurel oak, and others (FSU Herbarium).
Phenology
It has been observed flowering in August through October, and fruiting in August through November (FSU Herbarium).
Seed dispersal
Seed bank and germination
Fire ecology
This species occurs in areas that regularly burn, suggesting a level of fire tolerance (FSU Herbarium).
Pollination
The following Hymenoptera families and species were observed visiting flowers of Chamaecrista nictitans at Archbold Biological Station (Deyrup 2015):
Halictidae: Augochloropsis sumptuosa
Use by animals
A bee, Augochloropsis anonyma (Cockerell) was found on C. nictitans.[2]
