nerves on the young leaves beneath bearing white pubescence. Leaves 
cordate-ovate, obtuse, mucronulate, base shallowly cordate, about 3 in. 
long by 23 in. broad, glabrous, the older leaves slightly bullate ; petiole 
slender, a little shorter than the blade, with a large gland on each 
side at the back of the leaf-insertion. Peduncles axillary, standing 
raceme-like in the axils of the upper leaves of the short shoots, 
I-flowered, about } in. long, becoming 1 in. or more in fruit; 
pedicels slightly longer, thickening slightly upwards. Calyx glabrous, 
tubular; sepals elliptic-oblong, obtuse or emarginate, 7-8 lin. long, 
coriaceous, dark brown, the edges thinner and lighter in colour, becoming 
more than 1 in. long in the fruit. Corolla showy, salver-shaped, white, 
glabrous, 34-4 in. long; tube cylindric, 2} in. long, about } in. in 
diam, Ovary 4-celled. Capsule large, about } in. long, sub-

evil. 49. A robust shrub. Stems thick, woody, the younger minutely 
but densely grey tomentose, the older } in. thick, terete, glabrescent, 
yellowish, shining, rough when dry. Leaves orbicular, retuse, with 
truncate or subcordate base, 3 in. long, nearly as broad, covered on both 
surfaces when young with dense grey tomentum, ultimately glabrescent 
above, with sparse arachnoid tomentum beneath; petiole up to 24 in. 
long, 1 lin. thick, tomentose when young like the leaves, with on 
each side at the base of the lamina a long inconspicuous nectary. 
Flowers forming a dense many-flowered spike, with small young leaves 
at the end of the shorter shoots from which the older leaves have fallen. 
Peduncles up to din. long, terete, thick, grey-tomentose, 1-flowered ; 
subtending leaves petioled, oblong, 1} in. long, glabrous above, white 
on the margin, covered with white tomentum beneath especially on the 
nerves, beset with dense capitate glands and strongly bullate. Pedicel 
subclavate, 3—5 lin. long, like the sepals, glabrous or sparsely pulverulent, 
bearing a pair of opposite minute elongate triangular subobtuse bracts. 
Sepals 6-7 lin. long, about } in. broad, elongate-elliptic, obtuse or 
emarginate, coriaceous, yellowish-green, with paler membranous margin, 
the two outer shorter. Corolla salver-shaped, white; tube slender, 
cylindrical, 34-4 in. long, 2-2} lin. in diam., expanding above into a 
broad subrotate 5-lobed limb, about 3 in. in diam.; midpetaline areas 
plainly limited, yellowish. Stamens and style included, about equal to 
the tube ; anthers linear, din. long. Capsule large, ovoid, nearly 1 in. 
long, beaked with the persistent style-base, glabrous, shiny, dark
