Description
H. fasciculatum is a short lived perennial that has a single stem with reddish bark and forms thin adventitious roots. It can be distinguished from similar species, such as H. brachyphyllum by having flat leaves with no apparent fold [1].
Distribution
Ecology
Habitat
In the Coastal Plain in Florida and Georgia, H. fasciculatum can occur in Nyssa/Ilex communities, dry pond margins, ditches in pine flatwoods, titi bogs, rotted stumps, and dry bottoms of cypress ponds (FSU Herbarium). It responds to an annual, seasonal, or short-term change in water level by rapid colonization of favorable habitats and development of adventitious roots (Carr et al. 2006). Associated species include Ilex myrtifolia, Eriocaulon lineare, Xyris, Rhynchospora corniculata, and Lycopodiella. It grows in moist loamy sand (FSU Herbarium).
Phenology
It has been observed flowering in June and October and fruiting October through December (FSU Herbarium).
Pollination
The following Hymenoptera families and species were observed visiting flowers of Hypericum fasciculatum at Archbold Biological Station (Deyrup 2015):
Apidae: Apis mellifera, Bombus impatiens
Colletidae: Colletes nudus
Megachilidae: Coelioxys sayi
Cultivation and restoration
It contains volatile extracts primarily of composed of decyl acetate and gamma-muurolene, and has been used as cathartic agent in traditional Seminole Indian medicine (Crockett et al. 2008).
