broad, linear, acute or acuminate. Texture rigid: surfaces naked; main veins 

 of the segments distinct to the edge, united by transversing veins forming 

 + 6 quadrangular areolae on each side of the costulae. Sori in single rows 

 between the main veins near their anterior sides, sometimes confluent.
