G a t h e r e d by the Rev. H. Davies and by Mr. Turner m
North Wales and in Ireland. Dillenius observed it originally
on Snowdon. We have found it at Hafod, Cardiganshire. It
grows in the clefts of alpine shady rocks, ripening its fruit in
summer and autumn, and is perennial.
Nothing can be more distinct from the real Bryum cirratum,
which is a Grimmia. This is a true Dicranum, and of much
larger size. The stems form dense elastic tufts, an inch or
more in height, and are branched, very leafy, the summits of
the branches all nearly level. Leaves pale yellowish green,
imbricated, linear-lanceolate, acute, keeled, with one nerve;
serrated towards the point. When dry they curl inward. By
age they become very black, but remain on the stem. Fruit-
stalks lateral, several, erect, slender, generally solitary. Capsule
erect, elliptical, smooth, brown. Fringe purplish. Lid
awl-shaped, straight. Veil striated, at length torn at the edge.
