Morphological Description

Family Recognition in the Field: The single East TX species is typically epiphytic or found growing on rocks; the discrete round sori without indusia are found in single rows on each side of the midvein of the lobes of the deeply pinnatifid leaves; the lower leaf surfaces are conspicuously covered with peltate scales.


Notes: A cosmopolitan family treated today as including ca. 40 genera and ca. 500 species (Smith 1993c).
