PTEROGONIUM? caespitosum.
Matted Wing-moss.
CR YPTOGAMJA Musci.
Gen. Char. Caps, oblong, from a lateral scaly sheath.
F r in g e simple, of l6 linear upright teeth. V e i l generally
hairy.
Spec. Char. Stems branched, entangled, prostrate,
slender. Ultimate branches ascending, obtuse.
Leaves ovate, concave; revolute at the base;
minutely serrated at the summit.
F O R the same reasons as those in the foregoing page, we here
exhibit another presumed species of Pterogonium ; as little exposed
to uncertainty as any can be on the score of habit, and
undoubtedly nondescript.
This was gathered in Scotland, in 1810, by Mr. W. Borrer,
on rocks by the river at Dulsie bridge, but destitute of fructification.
The much-divided stems are entangled and prostrate,
throwing up numerous ascending, simple, obtuse branches,
clothed with larger leaves than those on the main stems, and of
a light bright-green colour-. The leaves are closely imbricated,
ovate, bluntish, concave, with a short rib at their base; revolute
in their lower part; finely serrated towards the point only.
