778 FERNS OF XORTH QUEENSLAND^ 



A. Beckleri (Hook.) Mett.; Polypodinm Beckleri Hook., Spec. 

 Fil., iv., 224; A^pidium ramosum var. Eumimdi Bail. 



Raveiishoe (by Falls), etc., Cairns district; July- Aug., 1913. 



Domin states (p. 62) that Bailey's plant is perfectly identical 

 with A. Beckleri. 



A. suBMARGiNALis Dom., Prodr., p.62. 



On south side of Bartle Frere, near Russell River; July, 1913. 

 Specimens also in Hb. Syd., from Herberton district; leg. Waller, 

 1908. 



Mr. Bailey questions the validity of this species, but my speci- 

 mens entirely agree with Domin's description, and are differenti- 

 ated from A. ohliterata by the submarginal sori and the character- 

 istic leaf- formation. 



A. tenella J. Sm.,( common in South Queensland and New South 

 Wales, and better known as Poly podium tenellum), I did not find 

 in the Cairns district, nor Domin's new species, A. prorepens. 



Nephrol E PIS Schott. 



N. BISERRATA (L.) Schott; iV. exaltata var, hiserrata Bak.; Aspi- 

 dium exaltatum var. longipinnum Bentham, Bailey et al.; 

 Aspidium acutnm Schkr. 

 Stoney Creek; and near Bartle Frere; July- Aug., 1913. 



N. HiRSUTULA(Forst.) Presl.; N. exaltata var. hirsutula Bak. 



Stoney Creek, etc.; July, 1913. 



Some confusion has crept into the series of ferns, of which N. 

 exaltata is the basal form, owning partly to the fact that in leading 

 descriptions of N. exaltata, the varieties "hiserrata'^ and "hirsu- 

 tula" are included. It is preferable, with Van A. van Rosenb. and 

 Domin, to regard these so-called varieties as distinct species. The 

 typical iV. exaltata is figured by Bailey, in his "Lithograms," t. 

 123. N. hiserrata has a much longer and more acute pinna, and the 

 sori are more distant from the margin ; w^hile N. hirsutula is dis- 

 tinguished by the woolly scales on the rhachis and surfaces, and 

 the erect, narrow acroscopic auricles at the base of the pinnae. 

 Domin rightly says, of .Y. hirsutula, "Ab affine N. exaltata var.
