I runks of trees. Fr. June. — Stems frequently as tall as in O. Lyellii. 

 The inner peristome is very peculiar, it is broad, pale-coloured, and com- 

 posed of moniliform joints, usually arranged in single rows, but not 

 unfrequently having other joints attached to their sides. Here, too, 

 they arise from an inner membrane to the capsule, as in Hypnum. 



9. O. Lyellii, Hook, and Taylor, (Mr. LyelTs Bristle-Moss); 

 >t<'ins erect elongated, leaves linear-lanceolate subundulate 

 carinated very acute crisped when dry. capsule oblong furrowed, 



cilia filiform, calyptra very hairy. Muse. Frit. ed. 1. p. 76.

First discovered on trees in the New Forest, Hants, by C.Ii/ell, Esq. 

 since ascertained to be not unfrequent throughout Britain, esperfallj in 

 subalpine regions. Fr. Aug. — Readily distinguished from the preceding 

 by its long, narrow and crisped leaves, and senile fruit. '1 he inner 

 peristome is, too, wry different, red, not moniliform, and arising from the 

 side of the teeth. Hedwig ha> probably confounded the two spci.it 

 well ;is the following, but they are truly distinct.
