elliptic, obtuse or acute or sabacuminate, narrowed (often suddenly) 

 from below the middle to the base, 4-|-5J in. long, 2 J-3| in. broad, sub- 

 coriaceous, finely pubescent to subtomentose on the nerves below ; 

 secondary nerves 12-15 on each side, rather spreading, straight or 

 gently curved ; petiole (if any) very short and winged from the decur- 

 rent blade. Inflorescences usually geminate from the youngest branch- 

 forks, dichotomously corymbose, many-flowered, glabrous or sparingly 

 pubescent below; peduncle about 2 in. long, moderately stout; bracts 

 ovate, subacute, up to 3 lin. long, caducous ; pedicels rather slender, 

 6-9 lin. long. Calyx subcampanulate, 5-6 lin. long, subherbaceous, 

 with a zone of glands above the base ; lobes rotundate, almost as long 

 as the tube, at last spreading or reflexed. Corolla deep yellow ; tube 

 4-5 lin. long, stout, constricted just above the middle, twisted ; lobes 

 obovate or elliptic, up to 9 lin. long. Stamens inserted above the 

 middle of the corolla- tube ; anthers 2-2 J lin. long, tips very shortly 

 exserted, tails rather short. Disc fleshy, annular, much shorter than

 on the nerves, at length glabrescent ; secondary nerves 9-12 on each 

 side, rather spreading and almost straight or oblique and gently curvea ; 

 petiole slender, 2-4 lin. long. Inflorescences geminate from the 

 young branch-forks, dichotomously corymbose or of paired pseudo- 

 umbels, rather loose, pubescent up to the calyces ; peduncles slender, 

 1-1 J in. long; bracts obovate-oblong, up to 6 lin. long, caducous; 

 pedicels slender, up to 10 lin. long. Calyx subcampanulate, 5-6 lin. 

 long, rather firm, with a zone of small glands somewhat above the 

 base ; lobes broad-ovate or ova-te-oblong, obtuse, as long as the tube, 

 porrect or sometimes reflexed. Corolla-tube stout, 4J-5 lin. long, con- 

 stricted at thue middle and mouth, twisted, finely tomentose within just 

 below the stamens, otherwise glabrous ; lobes obliquely obovate, wavy, 

 6-7 lin. long, horizontally spreading. Stamens inserted above the

 straight, very acute. Disc fleshy, annular, free, less than half the
