Hierarchy Level:  Association

Type Concept: This is an open woodland, the open structure perhaps maintained in part by prescribed burning, growing on exposures of Miami Formation oolite in the Florida Keys. The canopy is short (3-7 m) and is dominated by Metopium toxiferum, Leucothrinax morrisii, and Byrsonima lucida, with other tropical hammock species. Understory species present include Schizachyrium spp., Flaveria linearis, Croton cascarilla, and Borrichia frutescens.
