Falklands, etc.] fastigiatum, ramis erectis fastigiato-paniculatis.

Var. Magellanicum, Strait of Magalhaens and throughout Fuegia, the Falkland Islands, very abundant; Kerguelen's Land, J. D. H. fastigiatum, Port Famine, Capt. King.

I have in the former part of this work given my reasons at length for assigning these varieties to L. clavatum. The var. fasligiatum is a plant of a warmer climate than the var. Magellanicum, which inhabits not only the low-lands of Fuegia, the Falklands, and Kerguelen's Land, but also the lofty heights of the Cordillera of Peru and Colombia, and the mountains of New Zealand, Tasmania, and Lord Auckland's group.

I am quite unacquainted with this species, either as a Falkland Island or Magellanic plant.

Kerguelen's Land, in the fresh-water lake above Christmas Harbour, abundant, J. D. H.

After a careful comparison of this plant with English specimens of C. flexilis, I consider them to be the same species, and am confirmed in this opinion by my friend Mr. Wilson, who has studied the British species of this difficult genus very carefully; he says, that the points at the apices of the branches are, perhaps, longer than common in the Antarctic specimens. It is probably not an unfrequent plant in the southern temperate zone.

Var. 1 and 2, Hermite Island, Cape Horn; Kerguelen's Land, var. 1, on alpine rocks.

This species has in Europe frequently been confounded with A. rupestris, and we cannot assent to the remark in the 'Muscologia Britannica', that Dr. Mohr was the first to distinguish it accurately; since neither the description of Weber and Mohr (Bot. Tasch. p. 383), nor their citation of Dillenius (Hist. Musc. t. 73. f. 40), as a synonym for A. rupestris instead of A. Rothii, tends to prove that these authors understood the species.
