Diagnosis
Fertile pinnae long, with subparallel margins and thick straight rachis. Pinnules attached to the pinna rachis under right (90°) angle. Fertile pinnules lanceolate, long, narrow, straight or slightly curved toward the pinna apex. Each well developed fertile pinnule has more than thirty sori, disposed in two longitudinal rows on abaxial surface of the pinnule, each by both side along the midvein. Sori round, consisting of ovoid basal disc (receptaculum) and 9–12 sporangia attached to the basal disc under an acute angle. Each sporangium bears distinct annulus formed by large-sized specialized cells. Spores in situ are subtriangular, with trilete mark. Proximal surface of the spore is smooth, distal surface is finely vermiculate. Rays of the trilete mark don’t approach the spore equator. Sterile pinnules slightly wider than fertile ones, have pinnate- to reticulate venation and lanceolate or prolonged subtriangular outlines.
