    Moist. rocks; in fructification at Campsie, near Glasgow. About Powerscourt Waterfall, near Dublin, common, but barren. Fr. (fully ripe) April.—The stems are elongated, flaccid, loosely tufted, branched, branches spreading. Leaves lax, spreading, one third of an inch long, linear-acuminate, grooved, flexuose, entire, waved at the margins, which are not_at. all recurved; their substance is rather thick, yet tender, composed of such minute cellules as to have no appearance of being reticulated, the nerve strong and reaching to the point. rut rare. Seta scarcely an inch long, pale reddish-yellow, sometimes two from the same perichztium. Capsule cylindrical or oblongo-cylindrical, each with its side slightly unequal. id subulate, straight, two-thirds of the length of the capsule, reddish-yellow ; calyptra dimidiate. Pertstome of 16 equidistant, linear-subulate, somewhat torulose, red teeth, erect when dry, when moist forming a cone or arch over the mouth of the cap- sule.—The general habit of this plant is quite peculiar ‘among the Weissie, having loosely entangled, spreading stems and remarkably flaccid patent leaves, in these last particulars resembling T'richosto- mum Barbula, Schwaegr.; and still more Tortula tortuosa. The peristome, however, is that of a Weissia. In some respects it approaches in the general form of the leaves and of the capsule, WV. curvirostra; but that is abundantly distinguished by its erect, bright red, wiry stems, its leaves much shorter and smaller, less waved, so distinctly recurved at the edges as to be margined: and above all by its lid, whose beak is far shorter, more obtuse and oblique in its direction. In April, 1831, Dr. Greville and myself gathered numerous specimens in the Campsie ‘station, but the fruit was rare. 12. W. curviréstra, Hook. and Taylor, (curve-beaked Weissia); stems elongated wiry (usually red), leaves patent linear-subu- late margined with the revolute edge, nerve strong, capsule ovato-cylindrical, lid shortly rostrate oblique, teeth of the peristome subulate erect.
