442 SUBANTARCTIC ISLANDS OF NEW ZEALAND. [Systematic Botany. 



land, from Cape Colville southwards ; Australia and Tasmania ; Juan Fernandez ; 

 Fuegia and the Falkland Islands.) 



By far the most abundant fern of the southern islands ; found abundantly from 

 sea-level to a height of 1,000 ft. or more. At low levels, and particularly in the 

 shelter of the rata forest, it often forms a trunk 2-4 ft. high, thus assuming quite 

 the character of a low-growing tree-fern. 



Aspidium mohrioides, Bory. 



Asfidium mohrioides, Bory., Voy. Duper., Crypt., 267, t. 35 (1827) ; Hook, f:, 

 Fl. Antarct., ii, 392, t. 149 (1847) ; T. Kirk in Trans. N.Z. Inst., xiv, 

 386 (1882). Polystichum mohrioides, Presl, Tent. Pterid., 83 (1836). 



Auckland Islands : Kirk. (South America, from Chili southwards to Fuegia and 

 the Falkland Islands ; Amsterdam Island ; Marion Island ; South Georgia.) 



As I have stated in the Manual, Mr. Kirk's notice in the Trans. IST.Z. Inst., 

 quoted above, is the only authority for including this species in the lists. It was 

 not seen by any member of the expedition, and but for its very peculiar distri- 

 bution, which would seem to make its occurrence probable, I should not have in- 

 cluded it in the present enumeration. 



Aspidium cystostegia, Hook. 



Aspidium cystostegia, Hook., Sp. Fil., iv, 26, t. 227 (1862) ; Hook, f., Iiandb. 

 N.Z. Fl., 376 (1864). Polystichum cystostegia, Armst. in Trans. N.Z. 

 Inst., xiii, 364 (1881). 



Auckland Islands : Hills above Carnley Harbour ; Kirk, Aston. (New Zealand, 

 alpine districts from Mount Egmont southwards ) 



I have not seen specimens from the southern islands. 



Polypodium punctatum, Thunb. 



Polypodium punctatum, Thunb., Fl. Jap., 336 (1784) ; Hook. & Bak., Syn. 

 Fil., 312 (1874). P. rugulosum. Lab., PI. Nov. Holl, ii, 92, t. 241

 dium punctatum, Diels, Natiir. Pflanzf., i, 4, 177 (1905). Dryopteris 

 punctata, C. Chr., Index Fil., 287 (1905). 



Auckland and Campbell Islands : Moist places on the hills, especially under 

 the shelter of bushes ; Hooker, Chambers ! (Universally distributed throughout the 

 tropics and the South Temperate Zone, excepting Africa.) 



Campbell Island is apparently the most southern station for this species^ for 

 in America it does not reach the Straits of Magellan, and Tristan d'Acunha is its 

 southern limit in the Atlantic. 



Polypodium australe, Mett. 



Grammitis australis, R. Br., Prodr., 146 (1810) ; Hook, f., Fl. Antarct.,
