A large strong-growing shrub, with stiff spreading
branches: branches clothed with a brown glossy bark,
slightly viscous, and scarcely pubescent. Leaves petio-
late, cordate, tapering to a point, reticulately veined,
rugged and uneven, without pubescence, of a dark green
colour, margins undulate, minutely denticulate. Petioles
rather long, widened and fringed at the base, clasping
the stem, channelled on the upper side, and rounded on
the lower, slightly pubescent, and spotted with numerous
very small black warts or scales. Flowers large, white,
cymose, nodding before expansion, afterwards becoming
erect. Peduncles bracteate, pubescent. Bractes crossing-
each other, oblong, acute, keeled, concave, fringed, of
a reddish purple; lower ones smallest. Pedicles short,
thinly pubescent, rather viscous. Calyx of 5 sepals, the
2 outer ones largest, cordate, acute, smooth and glossy,
viscous, slightly pubescent, sides a little reflexed, inner
ones smaller, more taper-pointed and membranaceous.
Petals 5, white, with a light yellow spot at the base,
