Genus. — Lophodium. (See page 13G). 



Species. — Callipteeis. Caudex very stout, slowly creeping, 

 extending two or three feet : stipes nearly as long as the frond, 

 sparingly clothed with short, broad, pale, semihyaline scales : 

 frond very erect, narrow, linear, eglandulose, pinnate : pinnae 

 rather distant, short, somewhat triangular, pinnatifid, from five 

 to eight pairs nearly of the same length, but the fifth, sixth, 

 seventh and eighth pairs somewhat the longest, and the others 

 gradually approaching them in length, the distance between 

 each pair gradually decreasing from the base towards the apex: 

 pinnules decurrent, broad, serrated, blunt or rounded at the 

 apex, the lower ones slightly larger and longer than the upper : 

 involucre flat, scale-like, indistinctly reniform, its margin irre- 

 gular, free, except at the sinus, where it is attached to the cap- 

 suliferous vein : clusters of capsules crowded, often confluent, 

 confined to the upper part of the frond.

This species is well figured in the ' Flora Londinensis,' (tab.
