76'2 THE FLORA OF NORFOLK ISLAND, 



Pleris tremida, B.Br., var. Kingiana, Hook, and Baker, Synops. 

 Fil. p. 161. (P. Baueriana, Endl., Prod. Norf. 40). 



P. Baueriana, Endl., Prod. Norf. 37, appears to be a form of 

 P. tremula. 



19. Pteris aquilina, Linn., var. esculenta. (P. escidenta, 

 Forst., Endl., Prod. Norf. 36 : Pteridiiun aquilinnm, 'Kuntze). — 

 Pteris aquilina is separated in the Nat. Pfl. Fain, from the 

 genus Pteris, as Pteridium, on account of its double indusium. 



20. Pteris quadriaurita, Eetz. — P. Trattinickiana, Endl., 

 Prod. Norf. 42, and P. Zahlbruckneriana, Endl., Prod. Norf. 41, 

 both appear, from the descriptions, to be P. quadriaurita, but I 

 am doubtful. P. quadriaurita is a new record for the Island. 



21. Pteris incisa, Thunb. (Ilistiopteris incisa, Thunb., Agardh). 

 Recorded by Mueller in Game's List. Perhaps P. Brunoniana, 

 Endl., Prod. Norf. 38, is the species. 



22. Pteris marginata, Borz. — Recorded by Mueller (Journ. 

 Bot. xxii. 290). 



23. Pteris comans, Forst., Endl., Prod. Norf. 39. 



ASPLENIACE^. 



24. Blechnum"^ discolorum, Forst. {Lomaria discolor, 'WiWd.) — 

 This species does not appear to have been previously recorded. 



25. Blechnum lanceolatum, Spreng. {Lomaria lanceolata, 

 Spreng. : Stegania lanceolata, R.Br., Endl., Prod. Norf. 34). 



Perhaps this and the following are identical, or B. Norfolk- 

 ianum with acuminatum. 



Blechnum Norfolkianum, Hew. 



^^ Lomaria norf olkiana, Hew. (nov.sp. ) [Stegania, A. Cunn. MSS.), fron- 

 dibus glabris lanceolatis pinnatifidis, laciniis sterilibussubfalcatisacuminatis 

 integris apice subdentatis : infimis semiorbicularibus, fertilibus angustioribus: 

 Frons sterilis bipedalis glabra. Pinnas 3-4 pollicares. On the margins of 

 water courses in shady ravines." 



* Lomaria is merged in Blechnum by both Christ (Farnkrauter) and Diels 

 (Pflanzenfamilien).
