Description:
This community is characterized by a 7- to 13-m open canopy of <i>Pinus elliottii var. densa</i> over a well-developed subcanopy (4 m) of <i>Coccothrinax argentata</i> and <i>Thrinax morrisii</i>. In fire-suppressed areas, hardwood species may form a dense understory, but under a natural fire regime, these species are maintained as low shrubs. Tropical species occur as low, sparse shrubs with scattered grasses, forbs, and bare limestone. Greater than 50% of the ground surface is exposed rock, frequently sharp and jagged, and pitted with numerous solution holes and fissures. Typical shrub species include <i>Acacia farnesiana, Bourreria cassinifolia, Byrsonima lucida, Croton linearis, Lantana involucrata, Psidium longipes, Sideroxylon salicifolium, Chrysobalanus icaco, Ficus aurea, Ficus citrifolia, Morella cerifera (= Myrica cerifera), Myrsine floridana, Persea borbonia, Randia aculeata, Rhus copallinum, Sabal palmetto, Serenoa repens, Caesalpinia pauciflora, Catesbaea parviflora</i>, and <i>Strumpfia maritima</i>. Herbaceous species in these communities are predominantly perennials, with a mix of tropical and temperate species. Typical species include <i>Chamaesyce</i> spp., <i>Aristida</i> spp., <i>Andropogon ternarius, Schizachyrium sanguineum var. sanguineum, Sorghastrum secundum, Chamaecrista lineata var. keyensis, Evolvulus grisebachii, Linum arenicola</i>, and <i>Spiranthes torta</i>. This community occurs on elevated outcroppings of mid-Pleistocene marine limestone of the Miami Rock Ridge Formation. Although this community may be subjected to flooding by ocean waters for 1-3 days during hurricanes, conditions are typically quite xeric.
