Nearly worldwide, primarily tropical and subtropical regions.
Genera 8–10, species ca. 70 (3 genera, 6 species in the flora).
Cryphaeaceae are distinguished by the combination of creeping primary stems with firm spreading-erect branches, leaves with one costa, mostly immersed capsules, corticolous habitat, dull aspect, and pale peristome. Vegetative leaves of many species of this family are very similar. Cryphaeaceae, as treated here, comprise only Cryphaea, Dendroalsia, and Schoenobryum. Several closely related genera in the family occur outside of the flora area (H. Akiyama 1990; M. G. Manuel 1981). Other genera of the flora area (for example, Alsia, Forsstroemia) have been included in the concept of Cryphaeaceae by various authors, (M. R. Crosby and R. E. Magill 1981), but are here assigned to other families: Alsia to Leucodontaceae and Forsstroemia to Leptodontaceae.
