Description
H. myrtifolium is a native perennial shrub that is a member of the Clusiaceae family.[2] It is most recognizable by its clasping leaves, which are usually glaucous.[3]
Distribution
H. myrtifolium is endemic to the southeastern Coastal Plain, found mainly in Florida, and sparingly throughout southern Alabama, Georgia, and Mississippi.[2][4]
Ecology
Habitat
H. myrtifolium frequents pond-adjacent habitats, fresh-waterbodies. and the occasional marsh.[5][4] Other natural communities include the sandhills and flatwoods.[6] More specifically, H. myrtifolium can be found in dry loamy sands of open pine woodlands, moist loams of pine woodland swales, sand pine stands, and shaded swamps.[7] It is considered an indicator species of the peninsula savannas in Florida.[8]
Associated species include Hypericum harperi.[7]
Phenology
H. myrtifolium commonly flowers from April until June.[9] It has been observed flowering from May to July as well as October to December.[10][7].
Fire ecology
This species is commonly found in fire-dependent pineland habitats.[8]
Conservation, cultivation, and restoration
As it is uncommon in its range and depends on endangered habitat types, Hypericum myrtifolium is listed as G4. It is also considered imperiled in Mississippi.[11]
