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.
