Woods and banks, among bushes, frequent. Fr. Oct.— Allied to H.
purum ; but slenderer, more rigid and more compressed in the stems and
branches, which are of a red colour, best seen by holding the plant between
the eye and the light.

Not uncommon on rocks in the Breadalbane mountains. Fr. .
21. H. catenuldtum, Schwaegr. (catenulated Feather-Moss);

Wet rocks and in woods. Dargle and Powerscourt, near Dublin, Dr.
Taylor. Ben Lawers, Dr. Greville. Campsie hills, near Glasgow, Mr.
Arnott. Mill Dingle, near Beaumaris, and woods near Bangor, but always
barren, Wilson. Fr. ?—This has probably not unfrequently
been taken for Pterogoninm filiformc, and Mr. Mackay's specimens in E.
Bot. under the last-mentioned name, are H. catemdatum. The present
plant is a genuine Hypnum, having a single filiform process between the
segments of its inner peristome. The stems are closely tufted, from one
to two inches in length, rigid. Leaves rather remote, of a dark green
colour, their margins appearing as it were serrated from the papillae on
the surface. In our specimens, the nerve is short, not more than one
fourth of the length of the leaf, whilst in II. catenulatum of Schwaegr.
it is said to disappear beyond the middle.
