Common on trunks of trees (Fr. Winter) ;
growing in dense purplish-brown patches.
Stems about f inch long, creeping,
and branched. Leaves in two opposite
rows, distant below, and overlapping in
the upper portion of the plant so as to
conceal the stem, roundish, with
a small lobe or auricle at the base,

stipules, notched at the apex. Calyx reversely
heart-shaped, with a projecting angle on the underside
; the whole surface covered with minute fleshy
tubercles ; mouth greatly contracted. Capsule

On shady rocks and trees.
Scarcely exceeds i inch
in length, of a dusky, reddish-
brown colour, collected into
thin patches, firmly attached
to the rock’s surface, or more
rarely to the bark of trees.
Branches scarcely pinnately
disposed. When the tip of the — 21.
finger is pressed against the surface of the wet
plant a multitude of leaves adhere. Cells of the
leaves large. Calyx kidney-shaped, or nearly
round. It may be distinguished from Frullania
tamarisci by the wider cellulation of the leaves
