G a t h e r e d on Wascherley Edge in the county of Durham
by Mr. John Thornhill, and sent us by Mr. Winch. It is
indeed not uncommon upon stones in mountainous heathy
places j we have gathered it near Edinburgh. The capsules are
produced from March to May, nor are they of rare occurrence.
The stems are an inch or two high, branched and leafy,
forming dense perennial tufts. Leaves dull green, imbricated,
more or less curved to one side, lanceolate, keeled, single-
ribbed, entire, tipped with a white pellucid point, whose margins
are finely serrated, not toothed. Fruitstalks terminal,
almost always solitary, erect, brownish green, twisted, from
half an inch to nearly an inch long. Capsule quite erect,
cylindrical inclining to oval, smooth, brown, with a purple
orifice. Fringe shortish, red, its teeth united at the base in
pairs. Lid awlshaped, taper, reddish, about half as long as
the capsule. Veil of the same figure, greenish, split into many
parts at the base.
If the white serrated points of the leaves be attended to, this
species cannot be confounded with the following.
