394 Filicum were brought by Capt. King. It is represented in New Zealand by the G. Cunniughamii, Hook.; in Tasmania by G. tenera, Brown, and G. flabellata, Br.; and in Chili, north of Valdivia, it appears to be in a great measure replaced by the G. pedalis, Kaulf.

Falkland Islands (West Island?); ''Lieut. Robinson, Capt. Sulivan, Mr. Chartres''.

Very nearly allied to the G. acutifolia, but readily distinguishable by the revolute margins of the pinn&aelig; covering the sori; this character, together with the stout, rigid, and very coriaceous habit, appear to indicate its being a native of drier places than the former. It has hitherto been found only in the Falklands, in plains of Valdivia, and on the Island of Chiloe.

Falkland Islands; Gaudichaud.

I have seen no Falkland Island specimens except those collected by M. Gaudichaud, which are identical with others gathered by myself in Lord Auckland's group and Campbell's Island.

Falkland Islands, Gaudichaud, &amp;c. Var. Saururus, Kerguelen's Land, J. D. H.

The Falkland Island specimens are perfectly identical with others of British growth, but the var. Saururus is so different from any aspect of L. Selago found in Europe, that it requires the most perfect suite of specimens, showing the gradual passage of the one into the other, to prove their common origin. Such, however, exist, especially in volcanic islands, which seem peculiarly favourable to the production of this variety.

In its largest and handsomest form, the var. Saururus inhabits the Andes of Peru, the Island of Bourbon, and Kerguelen's Land. A more slender state, but not slenderer than what occurs amongst Andes specimens, is found in Tristan d'Acunha, St. Helena, and in some of the West Indian Islands.

The narrow form of var. Saururus was brought from St. Helena as early as 1702, and given to Dillenius, who figured it. On the Andes, and there alone, the Selago division of Lgcopodia assume a deep brick-red colour, which, however, affords no specific character, for the Saururus is as often wholly green as red, and at other times is only tinged with the latter colour at the apices of the leaves; and this is the case with the Kerguelen's Land specimens. It is difficult to imagine the cause for this tint of plants. On the gloomy Island of Desolation, it cannot be due to the tropical sun, nor to colouring matter contained in the soil, for it also occurs in two species which I believe are always parasitical.
