Roy. Bot. Gard. Edinb. x. 160 (1917). 
A spreading shrub about 4 m. high; branchlets short, laxly 
leafy towards the apex, the older ones covered with smooth 
grey bark; young branchlets finely lepidote, about 2.5 mm. 
thick, apparently not bristly; axillary leaf-bearing buds very 
small, and dormant at the time of flowering. Leaves elliptic- 
obovate or oblong-obovate, rounded to a very shortly cuneate 
base, acutely acuminate at the apex, 6-10 cm. long, 2.3-4 cm. 
broad, coriaceous, glabrous above when mature and slightly 
shining, slightly bullately reticulate, densely lepidote below, 
the scales pale brown and contiguous or overlapping, with a few 
larger ones scattered here and there, the body of the scales 
somewhat dry and depressed in the middle, with a narrow 
membranous fringe, the epidermis between the scales rather 
laxly papillous ; midrib impressed above, prominent below and 
rather densely lepidote ; lateral nerves 6—7 on each side of the 
midrib, a little impressed above, straw-coloured and flexuous 
below, obscurely looped and branched towards the margin ; 
petiole about 1 cm. long, grooved above, lepidote. Flower bud- 
scales thinly coriaceous, slightly keeled and densely lepidote 
towards the apex, apiculate, fringed with soft white hairs. 
Inflorescence 2-3-flowered, umbellate ; pedicels nearly 1.5 cm. 
long, densely lepidote with rather dry flake-like scales. Calyx 
saucer-like, undulately lobed, about 2 mm. long, densely lepidote 
outside and bristly with rather short stiff hairs on the margin. 
Corolla pale pink, about 7.5 cm. long; tube about 4 cm. long, 
infundibuliform, fairly narrow at the base, rather densely 
lepidote outside, and very finely pubescent towards the base ; 
lobes 5, broadly oblong, about 3 cm. long, lepidote outside 
except towards the margin. Stamens 10, unequal, exserted ; 
filaments pubescent towards the base; anthers 6-7 mm. long. 
Ovary 5-celled, 7 mm. long, very densely lepidote ; style as long 
as the corolla, rather densely lepidote in the lower %, crowned 
by a large deeply lobulate stigma. sule ;
