 cated, glabrous beneath ; basal scales large, linear, pale, spreading, mixed with

Hab. Queensland and New South Wales. We are indebted to Dr. David Moore for 

 material for separating this as a species.

 texture moderately firm ; both sides bright-green, glabrous, the lower slightly 

 furfuraceous on the main ribs ; veins distinct, 10-12-jugate, forked ; sori filling 

 up the whole of the fertile segments except the tip. 



Hab. Louisiade Archipelago, Macgillivray. Resembles closely the American A . ferox 

 in cutting and texture. 



58. A. glalra, var. A. Metteniana, Hance ; recep. densely paraphysate. Seem.

 stalked, l|-2 in. 1., in. br., cjit down to a narrow wing ; segm. close, ligulate, 

 blunt, obscurely toothed, 1 lin. br. ; texture subcoriaceous ; both sides green, the 

 lower densely pilose, with a few bullate scales on the ribs ; veins 4-6-jugate, 

 simple ; sori costular. Kuhn, Linn. 36. p. 152.

59*. A. Andersoni, Scott ; fr. ample, tripinnatifid ; rachises dark-castaneous, 

 naked, beneath rough, with raised points ; pinna; oblong-lanceolate, 1^-2 ft. 1. ; 

 pinnl. lanceolate-ligulate, subsessile, cut down to a narrow wing or the rachis, 

 4-6 in. 1., f-1 in. br. ; segm. close, lanceolate, bluntish, 1^-2 lin. br., distinctly
