nately beyond this I could not go. I may mention that 

 an old capsule, dark red also, sulcated and nearly erect, on 

 a seta of the same colour, was observed rather close to 

 the stem producing these objects. 



The following was found in three places near the base 

 of what are reckoned the highest cliffs in Great Britain. 



Bryum rubicundum, n. sp. In very dense convex, 

 widely extended tufts, in one instance 8 inches in longer 

 diameter, of a brilliant wine-red colour throughout ; stems 

 upright, red, about 1 inch long, simple but rather frequently 

 fastigiatety branched near apex ; leaves at first pale green, 

 quickly red, closely arranged around stem, upright, ap- 

 pressed, but often showing a slight contortion when dry, 

 including acumen about 7 mm. long, narrowly lanceolate, 

 pagina joining nerve above at an acute angle, the one side 

 joining at a higher level than the other ; nerve strong red, 

 near base about '11 mm. broad, tapering and excurrent in 

 a long, very slender, red, solid acumen, hair-like in upper 

 half, about 3 mm. long, margin reflexed below, composed of 

 three to five rows of very long, narrow cells up to apex, 

 where they join the acumen ; cells at base nearly bluntly 

 square, detached, about - 023 mm. across, above this group 

 cells elongato-hexagonal, -06-08 by •012--017 mm., the rest 

 of cells to apex smaller but of the same shape or acutely 

 rhomboid. I cannot recall having ever seen, in any other 

 Bryum, such a long slender acumen, nearly the length of 

 the leaf proper. 



Hypnum intortum, n. sp. In rather dense nearly up- 

 right tufts, green above, pale brown below, from 2 to 

 4 inches in height ; stems strong, pale, irregularly branched 

 below, densely pinnate above ; pinnae short, spreading 

 widely, shortening regularly upwards so that the whole 

 assumes a triangular form, branches ceasing considerably 

 below apex of stem, leaving this part bare ; stem leaves very 

 large — three or four times the length and breadth of the 

 branch leaves or nine times their area, — spreading nearly 

 at right angles to the stem, rather abruptly and broadly 

 expanded at base, narrowing also nearly as abruptly 

 into the long, tapering, curved acumen, nerveless, margin 

 plane serrated from base to acumen, and when this acumen 

 is broader than usual, serrated considerably up its margin :
