Hab. Mauritius. In habit not unlike A. cultrifolium, but different in texture and

 base rounded, especially on the upper side, the edge often sharply toothed ; texture 

 subcoriaceous ; veins once or twice forked ; sori in regular lines from the midrib 

 very nearly to the edge. Hk. Sp. 3. p. 238. 



Hab. Philippines, and Malayan Peninsula and Isles. A plant gathered by Cuming, 

 herbaceous in texture, with very broad involucres, is perhaps distinct.

 6-9 in. br., subdeltoid, with numerous horizontal pinnce on each side, the lower

 except that the base on both sides is distinctly auricled, the edge in the lower ones 

 bluntly lobed, sometimes one-third to halfway down, the base narrowed suddenly ; 

 texture subcoriaceous ; rachis naked ; lateral veins simple or once forked ; sori in 

 regular parallel rows extending from the midrib to the edge. Hk. Sp. 3. p. 250. 



Hab. Malayan Peninsula and Isles This comes very near to the last in texture, and
