Hypnum.] MUSCI-PLEUROCAKPI-PERISTOMI. 75
Taylor. On moist inclined faces of rocks, usually near rills, on the side of
Turk mountain and Cromagloun near Killarnev, rarely upon trees ; Mr.
Wilson. Fr. Oct. Dec.— The plant grows in large tufts : stems slightly
branched, scarcely half an inch high ; branches erect ; leaves rather loosely
imbricated, almost erect, of a delicate nearly membranous texture, faintly
reticulated, the margins thickened and somewhat waved, entire, those of
the periehectium are few, small, ovate, nerveless. Seta scarcely rising
above the stems, scabrous above. Capsule inclined, ovate, with an in-
distinct apophysis. Calyplra mitriform, nearly white, delicate, faintly
reticulated ; the base cut into fine capillary segments. Lid conicorostrate,
nearly as long as the capsule. Peristome large in proportion
to the size of the capsule, pale yellow : Outer one of 16 subulate teeth
expanding in water, inner of 16 slender cilia alternating with the outer
teeth, united by a membrane which scarcely rises beyond the mouth of
the capsule. (Wils.)
39. Hypnum. Linn. Feather-Moss.
Seta lateral. Peristome double : the outer of 16 teeth ; the
inner of a membrane cut into 16 equal segments, with filiform
processes frequently placed between them. Calyptra dimidiate.
(Muse. Brit. t. 3.)—Named from wvog, sleep, according to Bridel,
given to some kind of tree-moss or Lichen ; and by Ray ap-
plied to this Genus and its allies on account of some fancied
soporiferous property. Leshca, of authors, is here united to
Hypnum : for the characters by which it is separated (the absence
of the intermediate cilia orfiliform processes) is too minute
to be generally available to the student.
