G a t h e r e d by the late Mr. W. Brunton upon trees in
rivulets near Ripon, Yorkshire. The late Mr. R. Teesdale
observed the same on the trunks of willows, chiefly about the
roots, in Yorkshire, Wiltshire, and at Chiswick near London,
bearing capsules from June to September. Our specimens all
agree with those of Dillenius, and with what Dr. Swartz
sends as Hedwig’s plant, and yet his figure seems not altogether
expressive of it.
The stems are perennial, creeping, forming lax entangled
tufts, of a dull, dark,,or tawny green. Branches various in
length, scattered, upright or ascending. Leaves small, ovate,
entire, concave, bluntish, loosely imbricated, inclined toward
one side, each marked with a fine rib, most visible when dry,
in which state the rib projects. Sheaths pale, yellowish or
tawny, their leaves lanceolate, acute, without ribs, but when
dry so plaited as to seem ribbed. Fruitstalks slender, not
an inch high. Capsule erect, cylindrical, slender, pale
yellowish brown, smooth. Lid conical, short, blunt, reddish.
