Moist banks and stone walls, abundant in subalpine countries. Fr.
June.—The slender stems, which are pinnated, the long and uncinate
leaves of a brighter colour, together with their striae and serratures, abundantly
distinguish this from H. aduncum and all its affinities.
66. H. rugidosum, Web. et Mohr, (wrinkle-leaved Feather-
Moss); leaves secund ovato-lanceolate serrated nearly plane
crisped transversely when dry the margins recurved the nerve
reaching half-way. Web. et Mohr, Fl. Cr. Germ. p. 366.

On the ground, in heathy places, near Thetford, F. K. Eagle, Esq.—
Mountainous parts of Scotland, especially in Breadalbane. Fr. unknown.—
This lies on the ground in dense tufts of a yellow-brown
colour. The transverse undulations are peculiarly striking, even to the
naked eye, in which particular, as well as in the broader and shorter,
more plane, secund, but not falcate, leaves, it differs from all the varie-
ties of H. aduncum. The only species that is very closely allied to this
is the H. robustum (Muse. Exot.) of the N. W. Coast of America.
67. H. commutdtum, Hedw. (curled Fern Feather-Moss);
stems pinnated, leaves falcato-secund cordate very much acuminate
serrated their margins reflexed the nerve disappearing
