Description
H. gentianoides is an annual forb/herb of the Clusiaceae family native to North America and Canada.[1] It has scaly leaves that are arranged on erect and wiry branches. Flowers are tiny and yellow, and only open with sunlight. Fruit capsules are usually red in color.[3]
Distribution
H. gentianoides is found in the eastern half of the United States, as well as the Ontario region of Canada.[1] More specifically, it is distributed from Maine and Ontario west to Minnesota, and south to southern Florida and Texas.[2]
Ecology
Habitat
H. gentianoides proliferates in fields, rock outcrops, woodland borders, eroding areas, pond margins, and flatwoods.[2] It mostly grows in areas that are open with sandy or rocky soils; it can also tolerate partial shade.[3] Specimens have been collected from loamy loose sand, wet pine flatwoods, longleaf pine depression, and sandhills. [4] H. gentianoides responds negatively towards soil disturbance in historically forest longleaf pine communities in South Carolina.[5] It is listed by the USDA Natural Resources Conservation Service as a facultative upland species, where it most often occurs in non-wetland habitats but can also occasionally be found in wetland habitats as well.[1]
Phenology
Generally, H. gentianoides flowers from July until October.[2] 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]
Use by animals
It consists of approximately 2-5% of the diet for various large mammals and terrestrial birds.[8]
Conservation and Management
H. gentianoides is listed as endangered by the Iowa Department of Natural Resources Parks, Recreation, and Preserves Division. [1]
