 two or three feet ; stipes branched, as long as the frond, 

 sparingly clothed with short, broad, pale, semi-hyaline 

 scales ; frond very erect, narrow, linear, pinnate ; pinnae 

 rather distant, short, somewhat triangular, pinnatifid, from 

 five to eight pairs usually of the same length, but the fifth, 

 sixth, seventh or eighth pair somewhat longest, and the 

 others gradually approaching them in length, the distance 

 between each pair gradually decreasing from the base 

 towards the apex ; pinnules generally decurrent, oblong, 

 lobed, serrated, blunt or rounded at the apex, the lower 

 pinnules generally larger and longer than the upper ; 

 involucre flat, its margin irregular ; clusters of capsules 

 crowded, often confluent, confined to the upper part of the 

 frond.
