 glabrous shrub, 12 ft. high, with hook-branched slender tendrils from 

 the branch-forks ; young branches dark reddish -brown, glossy, with 

 minute lenticels. Leaves elliptic or oblong, shortly and abruptly or 

 gradually acuminate or obtuse, shortly cuneate at the base, oJ-4 in. 

 long, 1 J-2 in. broad, thinly coriaceous, somewhat glossy above, opaque 

 beneath, margins slightly wavy ; midrib flat or obscurely channelled 

 above, slightly convex below; secondary nerves about 15 to an inch, 

 fine, raised on both sides, with still finer, parallel tertiary ones between 

 them ; petiole 3 J lin. long. Flowers sessile, few, glabrous, in small 

 axillary clusters, slightly exceeding the petioles ; bracts minute. Calyx 

 J lin. long, glabrous ; sepals ovate, obtuse, ciliolate. Corolla glabrous 

 without ; tube subcylindric, 2 J lin. long, widest at J from the base, very

 tube. Stamens inserted near the base ; anthers erect ; filaments slightly 

 curved, very short. Ovary ovoid-globose, passing into a stout style 

 which is shorter than the ovoid-conical stigma. — Pierre in Bull. Soc.

 4-6 to an inch, with still finer, parallel tertiary ones between them, all 

 slightly raised on both sides.; veins obscure beneath ; a distinct outer 

 marginal nerve running close to the margin (apart from the inner, which 

 consists of the arches connecting the lateral nerves) ; petiole 3|^-6 lin. 

 long, rather stout. Cymes glabrous, 6- or more flowered, as long as the 

 petioles or slightly longer ; bracts minute ; pedicels up to 1 J lin. long.
