730 THE FLORA OF NORFOLK ISLAND, 



Niphoholus given as synoiiyiiious by Hooker tk Baker and 

 Bentham.* 



''Niphoholus serpens and Polypodium tenelliim, two climbing ferns, ascend 

 the trunks of the trees, in the northern portion of the Island " (Backhouse, 

 271). 



7. Polypodium confluens, R.Br., B.Fl. vii. (/'. glahrum, 

 Mett., Christ; P. acrostichoides, Sieb., non Forst.: JVi^jhobolus 

 confluens, R.Br., Nat. Pfl. Fam.). 



Apparently not previousl}^ recorded from the Island, unless the 

 following, which I cannot find in any list of synonj^ms, is the 

 fern in question : — 



'' Drynwglossum carnosum, J. 8m., Journ. Bot. v. 4, p. 66. Xiphobolus 

 carnosus, Blume, Fl. Jav. t. 19? On rocks" (A. Cunn,, in Heward). 



8. Polypodium acrostichoides, Forst. {Niphoholus acrosti- 

 choides, Bedd.) — Recorded by Mueller in Game's List. 



9. Polypodium pustulatum, Forst, (Syn. P, Billardieri, 

 R.Br., Endl., Prod. Norf. 19 : P. sccuulens, Forst.). 



Hooker & Baker (in Synops. Filic.) give P. pustulatum, Forst., 

 a,nd P. Billiardieri, R.Br., as distinct species; while Bentham 

 (B.Fl. vii.) and Christ unite them. P. scandeiis, Forst., is P. 

 pustulatum, Forst., according to Christ (Farnkrauter der Erde). 



Our herbarium material from Norfolk Island consists of only 

 one species, viz., P. pustidatum, Forst. 



10. Polypodium phy3iatodes, Linn. 



''Polypodium i^hymatodes, Brynaria vulgare, J. Sm. , Journ. Bot. v. 4, 

 p. 61; Linn., Mant. p. .306; Schk. Crypt, t. 9. On decayed timber in damp 

 woods " (A. Cunn., in Heward). 



11. Phegopteris punctata, (Thunb.) Bedd. (Polypodium 

 rugosulum, LabilL, Endl., Prod. Norf. 20 : Polypodiiwi puncia- 

 tum, Thunb., B.Fl. vii. 764: Nephrodium punctatum, Diels 1). — 

 Both Christ and Diels separate Polypodium punctatum from 

 Polypodium on account of the totally different habit and vena 



* Diels (Pflanzenfamilien) separates Niphoholus from Polypodium, 

 Bentham, Hooker, Baker and Christ unite it with Polypodium.
