Dioicous ; in tall bright green soft tufts 3 — 4 in. high. Stem erect, 

 densely coated with ferruginous tomentum, sterile shoots erect, lax- 

 leaved. Stem leaves longly decurrent, decurved towards point and at 

 sides so as to be convex, longish-oval, comal from a narrow base, oval- 

 spatulate, with a short recurved point ; limb of four rows of narrow 

 cells, teeth solitary, pointing forwards, short obtuse, of one or rarely 

 two cells, nerve excurrent in the point ; cells in oblique rows, irregular, 

 angular-roundish, with thick walls. Caps, pendulous, longish oval, 

 usually solitary, lid orange, convex with a point, peristome pale yellow- 

 green. 



Hab. — Watery heaths and about springs. Fr. 5 — 6, rare.

This fine species is very close to M. cuspidatum L., but differs in habit, 

 and the leaves are remarkably convex on the upper surface, from the bending 

 down of the wings, the cells also having a lining of collenchyma, which 

 swells by moisture and materially diminishes the cell-lumen, in which the 

 chlorophyl usually runs together into bands lying free in the cavity. The 

 true M. insigne Mitt, is confined to North America, and it was by mistake 

 he referred the Croft specimens to it in Hook. Journ. Bot. viii, 230. 



8. MNIUM CUSPIDATUM (L.) Neck. 



Dioicous ; with long trailing shoots. Leaves roundish and obovate, 

 slightly decurrent, with long sharp points; teeth long divergent, of 

 three cells. Caps, oblong, pendulous, lid convex. (T. LXXXII, B.)
