Description
H. gentianoides is an annual forb/herb of the Clusiaceae family native to North America and Canada. [1]
Distribution
H. gentianoides is found in the eastern half of the United States, as well as the Ontario region of Canada. [1]
Ecology
Habitat
H. gentianoides proliferates in fields, rock outcrops, woodland borders, eroding areas, pond margins, and flatwoods. [2] Specimens have been collected from loamy loose sand, wet pine flatwoods, longleaf pine depression, and sandhills. [3] H. gentianoides responds negatively towards soil disturbance in historically forest longleaf pine communities in South Carolina.[4]
Phenology
Generally, H. gentianoides flowers from July until October.[5] It has been observed flowering in May through July and September. [6]
Seed dispersal
This species is thought to be dispersed by gravity. [7]
Fire ecology
H. gentianoides is not fire resistant, and has no fire tolerance. [1]
Conservation and Management
H. gentianoides is listed as endangered by the Iowa Department of Natural Resources Parks, Recreation, and Preserves Division. [1]
