Forma typica: Rhizome scales rufoiis or fiiscons; fronds deltoid or 

 triangular-ovate, 2-pinnate; piiiniilac deeply piiinatifid to subpinnate in thc 

 lower part, broadly lobed to piniiatifid, serrate or tootlied in tlie iipper 

 part; segments obloiig \o obliquely ovate or obovate-cuneate, ,crenate to 

 serrate, the lowest posterior commonly very oblique, the lowest anterior 

 more or less aiiriculiform and commonly miich spreading or subhorizontal. 



V a r. Clarkei {A. Clarkei, Bedd., Ferns Br. Ind.. Supplem., 11, 

 tab. CCCLX): Fronds liiiear-laiiceoiate, deeply 2-pinnatifid, rather 2-pinnate 

 witli the pinnules obliquely ovate. lobed and serrate, connected by a 

 narrow costal wing, the lowest anterior lobe more or less auriculiform, 



V a r. dissecta (Clarke?): Like the type but the fronds 3-pinnate 

 with many of the lower secondary pinnulae deeply pinnatifid.

This species is very near A. uigripes Moore but the leaflets are more 

 fiuely (narrowly and deeply) incised in the upper part. — At first view il 

 reminds of Humata hymenophylloides Copel.
