C o m m u n ic a t e d by our very intelligent and indefatigable
friend Mr. G. Don from a marshy spot in the King’s Park,
Edinburgh. It bears its capsules in the spring and summer,
and is presumed to be perennial. Mr. Crowe gathered the
same on sandy turfy ground at St. Faith’s near Norwich.
It is known by the pale whitish hue of its leaves. The
stems are short and simple. Leaves pellucid, of a membranous
appearance, reticulated with rather coarse veins, lanceolate,
acute, single-ribbed, very obscurely serrated near the
point only. Fruitstalk solitary, an inch and half high, terminal,
erect, red, rather wavy. Capsule inclining, particularly
when dry, pear-shaped with a contracted base, curved,
obtuse, brown, opaque, not polished. Lid convex, almost
hemispherical. Outer fringe short, reddish; inner twice as
long, yellowish, formed of 16 teeth united by a reticulated
base.
