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.[2]
“Usually glabrous herbs or shrubs. Leaves usually punctate, simple, opposite, entire, usually sessile or subsessile, exstipulate. Inflorescence basically cymose; flowers perfect, regular, bracteates, subsessile or short-pedicellate, sepals 2, 4, or 5, persistent; petals 4 or 5, usually marcescent, yellow or pink; stamens 5-numerous, separate or connate basally forming 3-5 clusters or fascicles, filaments usually persistent; carpels 2-5, stigmas and styles separate or fused, ovary superior, 1-locular or partly or wholly 2-5 locular, placentation axile or parietal. Capsules basically ovoid, longitudinally dehiscent, styles usually persistent; seeds numerous, lustrous, areolate, cylindric or oblong. In general our species form a polymorphic complex with many intergrading taxa.” [3]
"Erect shrub, 8-15 dm tall, much-branched above, spongy-thickened below. Leaves linear-subulate or linear, with 2 longitudinal grooves below, largest usually 13-26 mm long, 0.7-2 mm wide, acute, base notched, sessile. Flowers terminal and axillary, solitary or in cymules. Sepals 5, similar to the leaves, 3-7 mm long, usually more than 4.5 mm long; petals 5, 6-9 mm long; styles united or 3, usually separate in fruit, ovary 3-locular. Capsules ovoid, ca. 4.5 mm long and 2mm broad; mature seeds not seen." [3]
Distribution
This plant's range extends from eastern North Carolina to southern Florida, and west to southern Mississippi.[1]
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, beaver ponds, titi bogs, rotted stumps, upland depression ponds, and dry bottoms of cypress ponds. [4] It responds to an annual, seasonal, or short-term change in water level by rapid colonization of favorable habitats and development of adventitious roots. [5] Associated species include Ilex myrtifolia, Eriocaulon lineare, Xyris, Rhynchospora corniculata, and Lycopodiella. It grows in moist loamy sand. [4]
Hypericum fasciculatum is an indicator species for the Peninsula Savannas community type as described in Carr et al. (2010).[6]
Phenology
H. fasciculatum has been observed flowering in February, April to July, October, and November with peak inflorescence in May.[4][7] It has been observed fruiting October through December.[4]
Pollination
Various pollinator species were observed visiting the flowers of Hypericum fasciculatum at the Archbold Biological Station. These include long-tongued bees from the Apidae family (Apis mellifera and Bombus impatiens), plasterer bees from the Colletidae family (Colletes nudus), and leafcutting bees from the Megachilidae family (Coelioxys sayi).[8]
Conservation, cultivation, and restoration
Cultural use
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. [9]
