Description
H. virgatum is a perennial forb/herb of the Clusiaceae family native to North America.[1]
Distribution
H. virgatum is found in the southeastern corner of the United States from Arkansas and Louisiana to Virginia and Maryland, as well as in Illinois, Indiana, and Ohio.[1]
Ecology
Habitat
H. virgatum is found in hardpan woodlands, rock outcrops, woodland borders, glades, and barrens (especially over mafic or ultramafic rocks).[3] It is also generally found in fields, open woods, and various dry roadsides.[4] Specimens have been collected from the loamy sand of longleaf pinelands, pond shores, moist marl-like soil in full sun, and damp meadows.[5]
Phenology
This species generally flowers from late June until September.[3]
Conservation, cultivation, and restoration
Due to taxonomic discussion, this species distribution is not fully known and is therefore listed as G4 on the global status scale. It is also considered vulnerable in Virginia, critically imperiled in West Virginia, and possibly extirpated in Maryland.[4]
