ad 18 cm longis, obtuse acuminatis, basi rotundatis ad acutis,

tinctis, anastomosantibus, reticulis laxis; paniculis axillaribus 
terminalibusque, axillaribus circiter 5 cm longis, terminalibus 
usque ad 12 cm longis et 5 cm latis, multifloris ; sepalis coriaceis, 
orbicularibus, margine leviter ciliatis; corolla circiter 12 mm

A scandent shrub apparently of large size, entirely glabrous 
except the inflorescences. Branches terete, smooth, very pale, 
the younger branchlets sometimes brown or dark-brown, never 
angled. Leaves coriaceous, oblong, 10 to 18 cm long, 3 to 8 
cm wide, smooth and shining, of the same color on both surfaces, 
and uniformly brownish or purplish-brown when dry, the apex 
shortly and obtusely acuminate, the base rounded to acute; lat- 
eral nerves 6 to 8 on each side of the midrib, distinct, somewhat 
curved, anastomosing, the reticulations lax, not prominent; pet- 
ioles stout, 1 to 2 cm long. Panicles axillary and terminal, 
when young sparingly pubescent with dark purplish-brown, 
short hairs, ultimately glabrous, the whole inflorescence uni- 
formly dark-brown when dry, the axillary panicles about 5 cm 
long, the terminal ones up to 12 cm in length and 5 cm in diam- 
eter, rather densely many-flowered. Flowers white or pale- 
yellowish, fragrant, about 12 mm long, their pedicels 3 to 4 
mm long, sparingly pubescent, ultimately glabrous. Sepals or- 
bicular, coriaceous, 3 to 3.5 mm in diameter, margins somewhat 
ciliate, otherwise glabrous. Exposed parts of the corolla in bud 
densely purplish-brown pubescent, the central pubescent part 
in flower ovate-lanceolate, 4 to 5 mm long; corolla tube 4 to 5 
mm long; the lobes in anthesis obcordate, about 12 mm wide 
and 8 mm long. Anthers ovoid-lanceolate, acuminate, 2.5 mm 
long. Fruits ellipsoid, glabrous, brown when dry, 1.5 to 2 cm 
long.
