Closely allied to the Malayan A. persicifolium J. Sm., and perhaps 

 not specifically different from that species; it differs by its nearly entire 

 and longer pinnæ, its short sori and its very regular venation. The lateral 

 veins are nearly always in groups of four: from a very short secondary 

 vein or, more often, from the costa of the pinnæ itself, spring out two 

 veins, of which the upper is always simple and soriferous, while the 

 lower is forked 2 — 5 mm. above the costa; the lower fork of these is 

 simple, while the anterior one is forked again once or twice. 



Christ has referred the specimen to A. vulcanicum Bl., which differs 

 from our new species by its coriaceous texture, pale colour, and equally 

 cuneate base of the pinnæ.
