Fissidens santa-clarensis, named for a province in Cuba, is restricted in the United States to peninsular Florida (Citrus, Collier, Dade, Levy, Manatee, Marion, Monroe, Polk, and Sumter counties). The species can be recognized by its abruptly narrowed, rounded-obtuse leaf apex, lenticularly-thickened dorsal and ventral laminal cells, short oblongifolius-type costa that in transverse section of the distal part shows four enlarged cells arranged in two rows, and similiretis-type of peristome. Collections of F. santa-clarensis were long assigned by American authors to F. radicans Montagne, a closely related species with caducous leaves, a broadly acute to rounded leaf apex, and an anomalous peristome with teeth undivided or irregularly divided.
