doubtless refer to 4. 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 Æ. 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 4. alpina, on account of the more gradual acumination 
of its leaves, which are full twice as long. It differs from 4. 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 perichztium. It is easily recognised by its habit.

Slightly differing from British specimens in its wider, less evidently papillose leaves, which 
dilated near the middle. Bridel (Bryol. Univ.) cites with doubt, Dillenius (Musc. 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 Linnzeus (as Bridel properly remarks) seems to refer. The secund 
foliage, generally ascribed to 4. rupestris, is not a constant character, even in specimen
