392 of Good Hope. Its aversion to damp or uniform heat is conspicuously displayed in its not being a native of New Zealand or Fuegia proper on the one hand, or of India or tropical Africa on the other.

Hab. Strait of Magalhaens ; Port Famine, Capt.King; Falkland Islands, B'Urville, Sfc.

The Magellanic specimens are larger, and have longer and more laxly imbricating pinnae, than those from the Falkland Islands ; which are characteristic of a climate less favourable to Ferns.

2. Aspidium (Polysticlium) coriaceum, Swartz, Syn.Fil. p. 57.

Hab. Chonos Archipelago ; C. Darwin, Esq.

A species apparently impatient of cold, for though inhabiting the damp west coast of Chili, as far south as the Chonos Archipelago and the dry climate of Patagonia, reaching there the latitude of Port St. Elena, it neither enters the Strait of Magalhaens, nor occurs in the Falkland Islands or Fuegia. It is almost universally diffused throughout the Tropics, and the temperate regions of the southern hemisphere.

Var. pinnulis profnndius sectis apicibus acutis.

Hab. Var. Tierra del Fuego, south part, C. Banvin, Esq.

The only specimen wdiich I have seen is imperfect, but appears merely a variety of the A. vestitwm, with rather narrower and more deeply cut pinnules, which are acute, but not pungent or spinulose ; the segments of the pinnules also are narrower, and the whole frond smaller. In other respects, and particularly in the clothing of the stipes, rachis, Sec, it exhibits all the characters of the species I have referred it to, which is a native of Juan Fernandez and Chiloe. I am not prepared to say how far all may be distinct from the British A. aculeatum, the incisions of the broader mucronate pinnules in the European plant are closer, and all aculeate, which is not the case with the typical states of A. vestitum ; and the clothing, too, is different.

This species is represented by the A. vemtstum, Homb. and Jacq., in Lord Auckland's group, and by A.proliferum, Br., in Tasmania.

5. ASPLENIUM, L.

1. Asplexium Magellanicum, Kaulf. En. Fit. p. 175. Hook, et Grev. Ic. Fit. 1. 180.

Hab. Strait of Magalhaens, Commerson ; Port Famine, Copt. King ; Hermite Island, Cape Horn, J.B.H.

A very pretty and distinct little species ; probably not uncommon between the latitudes of Concepcion and Cape Horn, on the west coast of South America. It has a very nearly allied representative in New Zealand; and another, the Asplenium laxitm, Br., in Tasmania.
