Although smaller in all its parts than Norwegian specimens for which
I am indebted to the kindness of Prof. Lindberg, the Scotch plant
unquestionably the same, and it is equally certain that it must take its place
in the long series of forms referable to Andr. petrophila, of which it is the most
marked variety, a position we prefer to that of establishing intermediate
subspecies. Th e areolation is also less completely circular than in the Scand
navian plant, which, it may be mentioned, grows associated with Andr. obovata
and Hartmani, two species still desiderata in the British Flora.

Common as this beautiful moss is with us, it is utterly unknown on the
continent, with the exception of a few stations m Norway, and Ites thus led
to great confusion in the synonymy of the older authors. In the Lmnean
herbarium it is represented by A. petrophila, and in Sweden by A . obovata, a
species having leaves gradually lanceolate in the upper half, the basal
L r g in quite entire, and the apical cells much larger and more angular.

This marked variety has a strong superficial resemblance to A . Hartmani,
but is readily distinguished by its more acute leaves, and much more minute
areolation.
