Taxonomic notes
Description
Distribution
It is found in the Coastal Plains of southwestern Georgia (Baker County) (Kirkman et al 2004).
Ecology
Habitat
Stylisma humistrata can be found in longleaf pine-oak woodlands, longleaf pine-wiregrass-scrub oak ridges, annually burned pinelands, mesic woodlands, floodplains, hardwood hammocks (FSU Herbarium), and subxeric and xeric areas in longleaf pine-oak communities (Carter et al. 2004). It can also be found along roadsides, edges of cornfields, recently logged oak-pine slopes, and old fields. Soil types include loamy sand, loam, and red sandy clay (FSU Herbarium). Associated species include Spigelia gentianoides and Quercus incana (FSU Herbarium).
Phenology
Flowers and fruits May through October (FSU Herbarium).
Seed dispersal
Seed bank and germination
Jayasuriya and his team found out that water uptake by manually scarified seeds was about 30 times greater than water uptake by non-treated seeds (2008)! This shows that S. humistrata exhibits physical seed dormancy. It does not require light for germination (Jayasuriya 2008).
