One of the commonest Ferns between the latitudes of Concepcion and Cape Horn on the west coast of South America, and also in the Falkland Islands, often covering the ground for many yards. It has also been collected in South Brazil by Sellow, and in Tristan d'Acunha, Kerguelen's Land, New Zealand, and in Tasmania ; throughout all which countries it retains its characters very markedly, and is altogether a most distinct species. The Blechium horenle is evidently its representative in the northern hemisphere, and is very similar in size, form, and habit, though abundantly distinct in the nature of its involucre.

Hab. South Chili, Fuegia, and the Falkland Islands, very abundant. This species is more confined in longitude but has a much wider range in latitude than L. aJpina. I have examined what appears to be the same from British Guiana (possibly a distinct species), from Brazil, and La Plata, on the east coast of South America ; and from Peru, Juan Fernandez, and Chili, on the west ; it also inhabits Tristan d'Acunha. Its New Holland representative is the L.procera, Br.

Mr. Gardner's name of zamioides is peculiarly applicable both to his Brazilian and my Falkland Island specimens, they smgularly resemble a Zamia iu habit and general appearance.

This, again, is a Fern of the Southern Ocean, being found in Tasmania, New Zealand, Lord Auckland's group and Campbell's Island, the west coast of South America, from Cape Horn probably all the way north to Lima, and on Tristan d'Acunha. I have seen no American specimens but Capt. King's, my own, and Cuming's (n. 1052). Its tropical representative is the beautiful little G. marginella. 8. GLEICHENIA, Sm.

Like all the pedate, erect, southern species of Gleichenia, this has a very narrow range, and is probably confined to the coast between the Strait of Magalhaens and Chiloe, whence the specimens quoted as Patagonian in Species
