Common in the scrubs of North Queensland. 



Domin describes the varieties fibrillosum and macrurum, and 

 refers to the vars. caudatum {A. caudatum Forst.), and Whittlei 

 (Bail.). V,ar. macrurum is the very large form occasionally met 

 with; I found it near Malanda and at Ravenshoe. The species is 

 so variable, that it hardly seems advisable to define varieties. 

 Compare Luerssen, "Fil. Graeff./' p. 155-6, 1871.

In scrub at base of Bartle Frere; July, 1913. 



This fern is quite comparable with A. Hookerianum Col., in 

 some of its forms, but as that species belongs to the far South 

 (New Zealand, Tasmania and Victoria), and as the North Queens- 

 land fern has a distinctive outline and other distinguishing- fea- 

 tures, it seems to me best to regard it as a separate species. 

 Bailey's description of the Queensland variety is as follows {loc. 

 cit.) : "Rhizome short or shortly repent, the crown and base of 

 stipes densely clothed with dark brown scales; stipes tufted, slen- 

 der, 4 or 5 inches long, dark brown and slightly scaly. Fronds 

 bipinnate, narrow -lanceolate, in outline attaining 8 inches in 

 length, and not over 3 inches wide in the broadest part; pinnules 

 cuneate, the lower ones often divided to the base,' the end inciso- 

 dentate. Sori usually long and narrow." 



It may be added that the scales, while similar to those of A. 

 Hookerianum, are more shortly-celled at the base, and are entire 

 or denticulate, while in A. Hookerianum they are subfimbriate ; also 

 that the first acroscopic pinnule on each pinna is more or less 

 prominent, and grows parallel to the rhachis, that the petioles of 

 the pinnae are much shorter than in A. Hookerianum (sometimes 

 almost none), and that the texture of the leaves is firmer and 

 closer than in that species.
