19G THE VOYAGE OF H.M.S. CHALLENGER 



Previously to 1S73 this fern, which is easily distinguished from its nearest allies, was 

 only known from the extreme south of America, the Falkland Islands, and one or two 

 places in the mountains of Chili; but in 1879 it was discovered in the mountains of 

 Northern California, at an altitude of 7500 to 8000 feet, and De l'Isle collected it in 

 Amsterdam Island the year after (1874) Moseley found it in Marion. 



Polypodium (Grammitis) australe, Mett. 



Poli/podium (Grammilis) australe, Mett., Polypod., p. 36 ; Hook, and Bak., Synop. Fil., p. 322. 



Marion Island. Moseley. 



Widely spread in the south temperate zone, including the Tristan da Cunha group and 

 Amsterdam Island. 



Mr Moseley 's Marion Island specimens of the plant are dense tufts, bearing fronds from 

 a quarter to three quarters of an inch long. 



[Polypodium vulgare is recorded from Marion Island in the Botany of Kerguelen 

 Island (Phil. Trans. Boy. Soc. Loud., clxviii. pp. 16 and 23), but no specimen can be 

 found, and it is probably an error, arising from a confusion of the lists.]

Marion Island. Moseley. 



All round the temperate zone of the southern hemisphere ; and the typical form is as 

 widely dispersed in northern countries having a cold damp climate.

Marion Island. Moseley. 



South Africa and the mountains of Western Tropical Africa, South America, and in 

 most of the islets from Ascension to Kerguelen. Typical Lycopodium selago, Linn., is 

 almost universal in damp, cold regions. We have been guided by Mr J. G. Baker in 

 retaining specific rank fur fjycopudium saururus.
