1 92 E. B. COPELAND : 



rather obtuse, broad fronds, and broad paleae; but it is a much 

 larger fern in all parts, and differs also in the exceedingly 

 rigid sterile fronds and continuous but low and compact sori.

Luzon Isl., "Ad Reservationem silvestrem lamaoensem" 

 100 m. s. m. (Copeland no. 1399, type, no. 243); Culion Isl. 

 (Merku^l no. 482). 



Tnis plant is very near to A. pliilippeuse, but differs in 

 the shape of the pinnae, usually right-angled at the base, in 

 their rather shorter petiolules. and very prominent venation, 

 as well as in the winged stipe, rachis and petiolules. As far 

 as I know, no description of A. jJteropiis R. Br., based on 

 S. African material, has ever been publislu^d, and I do not 

 know how completely it may resemble this plant.
