Hab. Var. Magellanicum, Strait of Magalliaens and throughout Fuegia, the Falkland Islands, very 

 abundant; Kerguelen's Land, /. D. H. \zx.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. fasligiatitm 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.

After a careful comparison of this plant with Engbsh specimens of C.fiexilis, I consider them to be the same 

 species, and am confirmed in this opinion by my friend Mi - . 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.

This species has in Europe frequently been confounded with A. rupestrig, 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. Muse. t. 73. f. 40), as a synonym for 

 A. rupestris instead of A. Rothii, tends to prove that these authors understood the species. The illustrative figures
