Neai: A. callifolium, BL, but the fronds spathulate-lanceolate, relatively 



horter and broader, narrowed gradually into the short, winged stipe, with 



more distict costa in the lower part; paraphyses linear. — Distinct enough 



rom callifolium if typical specimens only are vieWed, but passing into it by 



iitermediate forms, and it is impossible to draw the line between them.
