 allied to A. munitum and A. falcinettum. 



A. auriculatwn Sw. There are two plants in this present col-

 obliquum Don, but with subinargmal sori.— Mount Omei, Faber 

 1038, 1040. Also Kwantung, Ford 225. 2, gtmaphyllum, nov. var.,

 spinulose conspicuously auricled pinnae much cut away on the lower 

 side of the midrib.— Mount Omei, 3000 ft., Faber 1035.
