The classification of the ferns is still in a somewhat unsettled 

 condition. In the following pages, I have followed, as far as I 

 could, the arrangement that Mr. Betche and I propose to follow 

 in our forthcoming Census of the Plants of New South Wales. 



I have drawn attention to some points that require clearing 

 up. In some cases, in translating names to their now accepted 

 equivalents, it has occurred to me that the finds require con- 

 firmation. 



HYMENOPHYLLACE^. 



1. Hymen OPHYLLUM multifidum, Swartz. — The ubiquitous ff. 

 tunhridgense does not appear to have been found on the Island. 



2. Trichomanes apiifolium, Presl. (?'. Bauerianum, Endl., 

 Prod. Norf. 50). 



" The Peperomias grow also on moist rocks, on the dark sides of which 

 Trichomanes Bauerianum, a membranaceous fern, of great beauty, forms 

 tufts exceeding a foot in height " (Backhouse, 267). 



3. Trichomanes humile, Forst., Endl., Prod. Norf. 49. 



POLYPODIACE^. 



4. ViTTARiA elongata, Swartz { V. rigida, Kaulf., Endl., Prod. 

 Norf. 35. — On tree-fern stumps; is possibly a variety of the type). 



5. PoLYPODiUM tenellum, Forst. {Arthropteris tenella, J. Sm.: 

 P. tenellum in Endl., Prod. Norf. 18). 



Diels (Pflanzenfamilien) separates ArthrojJieris from Folypo- 

 diurn on account of the articulate pinnae. 



6. PoLYPODiUM SERPENS, Forst. {Niplioholus rupestris, Kaulf. : 

 iV. serpe7is, Endl., Prod. Norf. 21). 



Niphobolus serpens,'End]., seems to be synonymous with Fol)/- 

 podium serpens, Forst., though Niphobohis rupestris is the only
