396 FLOKA ANTAECTICA. [Fuegia, the 



and observations show tbat A. alpina of Weber and Mohr (Bot. Tamil, t. 11. f. 3, 5), is only a state of A. rupestris, 

 with leaves spreading in all directions. This is confirmed by the fact that A. alpina of Mougeot and Nestler 

 (Stirp. Crypt. Voges. no. 115), is that very form of A. rupestris to which we allude. The figures of Dillenius doubtless 

 refer to A. alpina ; but the absence of a separate figure of A. rupestris, and the remark, " in rupibus surculi e fusco 

 rufescunt" (p. 507), prove that this author considered both these as varieties of one species. The true A. alpina 

 may always be known from A. rupestris by its obovate dark glossy leaves, and its longer and more robust stems.

With some hesitation we venture to separate this from A. alpina, on account of the more gradual acumination 

 of its leaves, which are full twice as long. It differs from A. acutifolia in having the leaves considerably larger, 

 the lower part more suddenly dilated, and the base not gibbous ; also in their dark colour and glossiness, and in the 

 more evident perichffitium. It is easily recognized by its habit.

Slightly differing from British specimens in its wider, less evidently papillose leaves, which are more suddenly 

 dilated near the middle. Bridel (Bryol. Univ.) cites with doubt, Dillenius (Muse. p. 507. t. 73. f. 40) as a synonym 

 for this species, but the description of Dillenius distinctly mentions the nerved leaves which are characteristic of 

 A. Rothii, to which species even the description of Linnaeus (as Bridel properly remarks) seems to refer. The secund 

 foliage, generally ascribed to A. rupestris, is not a constant character, even in specimens gathered in the same locality.
