Fronds pinnate, narrow elongate, herbaceous or sub-coriaceous, the pinnfe articulated. Rhizome short erect, producing 
elongated slender stolones which bear fasciculate crowns at intervals ; or elongately creeping ; sometimes tuber bearing. (Moore.)

pinnate, pinnae numerous approximate ^-1 inch long glabrous, horizontal from a truncate or cordate base, more or less auricled 
above, oblong obtuse, or especially the fertile ones crenated, rarely acuminate, often subfalcate, lower and sterile ones shorter and more 
obtuse, auricle acute, sori transverse about equidistant from the margin and the costa, involucres firm, coriaceous reniform or nearly half-
