fronds, and, secondly, elongata, in which the fronds are pinnatifid. But it was long 

 ago proved that elongata commonly produces simple fronds, and Patersoni has also 

 been found with pinnatifid ones, so that the supposed distinction falls to the 

 ground. The specimens brought from the Auckland Islands show both forms of 

 fronds. 



Diels, in the " Pflanzenfamilien," and Christensen in the more recent " Index 

 Filicum," have both followed Mettenius in reducing Lomaria to Blechnum, and it 

 must be confessed that the two genera are much too closely allied. 



Lomaria discolor, Willd. 



Osmunda discolor, Forst., Prodr., n. 413 (1786). Lomaria discolor, Willd., 

 Sp. Plant., V, 293 (1810). Hook, f., Fl. Nov. Zel., i, 30 (1855). Blech- 

 num discolor, Mett., Fil. Lips., 64 (1856). 



Auckland and Campbell Islands : Hooker. (Throughout New Zealand ; Nor- 

 folk Island ; Australia and Tasmania.) 



This is not mentioned in the " Flora Antarctica," but both Sir J. D. Hooker, 

 in the Handbook, and Sir W. J. Hooker, in the " Species Filicum," give it as a native 

 of the Auckland and Campbell Islands. So far as I am aware, it has not been found 

 by any recent collector, and the supposition arises that large forms of L. dura (a 

 species which was not recognised at the time of Hooker's visit) were taken for it. 



Lomaria dura, Moore. 



Lomaria lanceolata. Hook, f., Fl. Antarct., ii, 110 (1844), not of Spreng. 

 L. dura, Moore in Gard. Chron., 1866, 290 ; Hook, f., Handb. N.Z. 

 FL, 748 (1867). Blechnum durum, C. Chr., Ind. Fil., 153 (1905). 



The Snares, Auckland, Campbell, and Antipodes Islands : Rocks and woods 

 near the sea, abundant ; Hooker, Kirk ! and all subsequent collectors. (New 

 Zealand, coastal localities from Banks Peninsula and the Chatham Islands 

 southwards.) 



I think there can be no reasonable doubt that the Lomaria lanceolata of the 

 " Flora Antarctica " is identical with Lomaria dura. No subsequent traveller has 

 met with L. lanceolata ; and L. dura is much too abundant in the islands to have 

 escaped the notice of such a keen observer as Hooker. 



Lomaria penna-marina, Trev. 



Polypodium penna-marina, Poir., Encycl., v, 529 (1804). Stegania alpina, 

 R. Br., Prodr., 152 (1810). Lomaria alpina, Spreng., Syst. Veg., iv,
