A REVISION OF THE CHAMAESYCE-DELTOIDEA (EUPHORBIACEAE) COMPLEX OF SOUTHERN FLORIDA

Morphological investigation of the Chamaesyce deltoidea complex demons trates a lack of sharp boundaries between the taxa. In combination wit h distributional data, the observed patterns of morphological variatio n suggest that the complex is best treated as a single polymorphic spe cies. New combinations are proposed for Chamaesyce pinetorum and C adh aerens to provide a consistent treatment for the morphological groups within the complex. The current conservation status of each morphologi cal group is reviewed.
