Varieties: H. ambiguum Elliott[2]


G. galioides is a perennial subshrub in the Clusiaceae family that is native to North America. [1]


H. galioides is found throughout the southeastern United States, specifically in Florida, Georgia, South Carolina, North Carolina, Alabama, Louisiana, Mississippi, and Texas. [1]



H. galioides is commonly found in wet pine savannas and flatwoods, pools, edges of bottomlands. [2] , and lowlands. [3] Specimens of the species have been collected from habitats including edge of swampy woods, moist loamy sands near a vernal pool, low wet swale in a prescribed fire pine region, pine plantation, oak hammock, and longleaf pine savanna. [4] It is listed by the USDA Natural Resources Conservation Service as an obligate wetland species that is almost exclusively found in wetland habitats.[1]

Associated species include Cyrilla parviflora, Salix humilis, Cephalanthus occidentalis, Saccharum sp., Dichanthelium scoparium, Smilax rotundifolia, Proserpinaca pectinata, Hypericum crux-andreae, and others.[4]


H. galioides generally flowers from June until August.[2] It has been observed flowering in May and June. [5]

Seed bank and germination

This species was not found in the seed bank even though herbaceous vegetation was found in longleaf pine sites.[6]

Fire ecology

H. galioides has been observed in areas that are frequently burned.[4]
