Description
H. tetrapetalum is a slender plant, usually with few branchings (FSU Herbarium). As its name implies, this species has a tetramerous calyx and corolla (FSU Herbarium).
Distribution
Ecology
Habitat
H. tetrapetalum occurs in wet sandy soils, like those of wetland woodlands, mesic flatwoods, or the margins of Karst ponds (FSU Herbarium). It can also occur in disturbed areas like roadsides (FSU Herbarium).
Phenology
This species has been observed flowering in August (FSU Herbarium).
