Auckland, Campbell, Antipodes, and Macquarie Islands : Not uncommon in 

 all situations, from sea-level to the tops of the hills ; Hooker and all subsequent 

 collectors. (Throughout New Zealand ; Australia and Tasmania ; Fuegia ; Falk- 

 land Islands ; Tristan d'Acunha ; Amsterdam Island ; Kerguelen Island ; Marion 

 Island.) 



The Grammitis rigida of Hombron and Jacquinot, judging from their drawing 

 and a couple of specimens collected by Dr. Cockayne, has a very distinct appearance, 

 and should be distinguished as var. rigida. The fronds are often 6 in. long by ^ in. 

 broad. 



Christensen, in his " Index Filicum," proposes to substitute Willdenow's name 

 of Billardieri for Brown's australe. Both names were published in the same year, 

 and in the absence of any positive assurance as to which appeared first it seems 

 highly inadvisable to disturb the present nomenclature, which has received almost 

 universal acceptance. 



Polypodium grammitidis, R. Br. 



Polypodium grammitidis, R. Br., Prodr., 147 (1810) ; Hook, f., Fl. Antarct., 

 i, 111 (1844). Grammitis heterophylla, Lab., PL Nov. HolL, ii, 90, t. 239

Auckland Islands : Apparently not common ; Hooker, Kirk ! Tennant ! Camp- 

 bell Island : Hooker (Handbook). (Throughout New Zealand ; extra-tropical Aus- 

 tralia, and Tasmania.) 



I have seen no specimens from Campbell Island, which is not quoted as a habitat 

 in the " Flora Antarctica," although it is in the subsequently issued Handbook. 



Polypodium Billardieri, R. Br. 



Polypodium Billardieri, R. Br., Prodr., 147 (1810). P. diversifolium, Willd., 

 Sp. Plant., V, 166 (1810) ; C. Chr., Index Fil., 523 (1906). Phymatodes 

 Billardieri, Presl., Tent. Pterid., 196 (1836) ; Hook, f., Fl. Antarct., 

 i, 111 (1844). 



Auckland and Campbell Islands : Common on rocks and on trunks of trees, 

 usually at low elevations. (Throughout New Zealand ; Norfolk Island ; Lord Howe 

 Island ; Australia and Tasmania.) 



Auckland Island specimens show no points of difference from the ordinary form 

 of the species in New Zealand.
