Hab. Abundant on dry shady roeks ; near the Strid and other parts of Bolton 

 ,woods, Wharfdale ! Found with capsules. May 1857 ! Ardingly Bocks, Sussex, 

 W. Mitten (sub-nom. J. trichomanoides) ! ft Bolton woods ! Malham Moor, July 10,

Tufts broad, depressed, densely humifuse, attached to the surface 

 of (calcareous) rocks, and having the habit of Saccogyne viticulosa. 



Stems serpentine-flexuose, creeping, depressed or arcuate, simple 

 and prolonged from the apex, or irregularly branched, olive-brown, 

 purplish near the base, brittle when dry. 



Rootlets numerous from the bases of the leaves, translucent, 

 tawny. 



Shoots leafy throughout (f. 11, 2), complanate, depressed, or 

 ascending only at the apex, rarely fertile, from f " to 1\'' long by a 

 line in breadth, tapering a little towards each extremity, in older 

 plants interrupted from the annual growths, the earlier leaves being 

 smaller and more distant. Branches more or less numerous, ax- 

 illary or proceeding from the ventral aspect, growing in the same 

 plane as the main shoots, sometimes producing shorter ramuli. 



Leaves elliptic-ovate (f. 11, 3) or quadrilinear (f. 11, 5), about 

 aV' in length, distichous, alternate, horizontally imbrica,ted, sub- 

 cbmplanate, the terminal ones ascending and connivent; apex 

 rounded and obtuse, retuse, or emarginate (f. 11, 3, 4, 6) in hi-, 

 tri-, or even quadri-dentate (f. 9) ; dorsal margin scarcely decurrent, 

 ventral entire, plane or waved, and like the summit a little recurved, 

 so that the surface is slightly convex, but much less so than usual 

 in this genus.
