Description: Communities dominated by ~Hypericum lissophloeus$ (shrub to 4 m tall), in sinkhole ponds and lakes in the Florida Panhandle, have other unique components. ~Hypericum lissophloeus$ forms a dense tall-shrub layer 3-5 m tall on the outer margins of the steeply sloping pond margins. Other associated species include ~Chrysoma pauciflosculosa, Hypericum reductum, Lupinus westianus var. westianus, Panicum virgatum, Andropogon glaucopsis, Andropogon capillipes, Panicum hemitomon, Centella erecta, Dichanthelium$ spp., ~Lachnocaulon minus, Ludwigia suffruticosa$, and ~Eleocharis$ spp. This alliance is limited to a single association which is endemic to sinkhole ponds in Bay and Washington counties, Florida. The group of sinkhole ponds vegetated with this alliance are unusually large, steep-sided, and deep, with as much as 30 m elevation change from rim (sandhill) to center. The hydrology is seasonally flooded, but the amplitude is great, with the zone where ~Hypericum lissophloeus$ is concentrated being flooded as much as 1.5 m deep, or being exposed up to 1.5 m above the water level.
