Worldwide, mostly tropical and subtropical regions.
Genera 3, species ca. 150 (2 genera, 11 species in the flora).
The Calymperaceae are defined by clasping leaf bases with cancellinae, absence of stem central strand, usually thickened and toothed leaf margins, mainly tropical-subtropical range, corticolous habitat, and common production of uniseriate leaf-tip gemmae. Plants of the family are specialized for water capture and retention by their sheathing leaf bases, and the large, empty, porose cells of their cancellinae. The habitat is typically on bark but many taxa occur primarily on decaying wood, rock, and soil. Our taxa occur almost exclusively in the southeastern United States.
