and observations show that A . alpina of Weber and Mohr (Bot. Tasch. 1 .11. f. S. 5), is only a state of rt. rupestris,
with leaves spreading in all directions. This is confemed by the fact that rt. alpina of Mougeot and Ncstlw
(Stirp. Orypt. Foyes. no. 116), is that very fom of rt. rupestris to which we aUtide. Tlie figures of Dillenins doubtless
refer to rt. alpina; but the absence of a separate figure of rt. rupestris, and the remai-k, “ in rupibus surculi e fusco
rufescunt” (p. 607), prove tbat this author considered both these as varieties of one species. The true A. alpina
may always be knowm from rt, rupestris by its obovate dark glossy leaves, and its longer and more robust stems.

With some hesitation we venture to separate this from rt. alpina, on account ofthe more gradual acuminatioii
of its leaves, which ai-e fob twice as long. It differs from rt. acutifolia in having the leaves considerably larger
the lower part more suddenly dilated, and the base not gibbous ; also in thefr dark colour and glossiness, and in “thé
more evident perichætimn. It is easily recognized by its habit.

Sbghtly 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, DiUenius (Muse. p. 607. t. 73. f. 40) as a synonym
for this species, but the description of DiUenius distinctly mentions the nerved leaves which are characteristié of
A.Bcthii, to which species even the description of Linnmus (as Bridel properly remarks) seems to refer. 'The secund
fohage, generally ascl'ibed to rt, rupestris, is not a constant character, even in specimens gathered in the same locabty.
