COMMUNICATED by Mr. Hooker from Scotland, where
Lightfoot first observed it to he frequent on the Highland rocks.
The stems form close tufts, about half an inch high, and
are nearly upright, divided at the base; their branches bluntly
quadrangular, swelling upwards, entirely covered with numerous,
two-ranked, closely imbricated leaves, which are of a
dull green, mostly tinged with brownish red, of a broadly el.
liptical concave figure, entire at the edges, but cloven with a
sharp notch at the top. The upper pair are much the largest,
enfolding each other, but rather inflated, concealing the sheath,
which is very minute. The marginal part of all the leaves is,
to a considerable extent, white and pellucid. The fruitstalk
is scarcely two lines long, white and tender. Capsule of four
elliptical black valves,
J.julacea, to which this has been compared, has its leaves
imbricated in every direction,
