T h i s Orthotrichum, found by Mr. Winch and Mr. Thornhill
on trees in Causey wood, also at Pont Bourn, and other
places in the county of Durham, was justly determined as a
new species by the late Mr. W . Brunton of Rippon, of whose
observations we have partly profited in the following description.
The stems grow in tufts, and are about 3 lines high, somewhat
branched or divided. Leaves bright green, lanceolate,
acute, beardless, keeled, single-ribbed, revolute, entire, spreading
; slightly twisted, but not curled, when dry. Fruitstajks
longer than the leaves, solitary, twisted, yellowish, upright.
Capsule erect, cylindrical inclining to ovate, pale, with 8
distinct ribs and as many furrows, Lid shortish. Fringe of
16 red, spreading, external teeth, and as many internal, in-
flexed, pale bristles. Veil conical, smooth and shining, destitute
of hairs, crenate at the base.
