 glabrous from the beginning. Leaves sessile, rarely sub.^es.sile, elliptic 

 or elliptic-oblong, acute or obscurely acuminate, narrowed from the 

 middle downwards, obscurely and minutely cordate or rounded at the 

 base or decurrent on the very short petiole, 4-8 in. long, 2-4 in. broad, 

 papery, usually more or less softly pubescent below, especially on the 

 midrib, rarely quite glabrous; secondary nerves 11-13 on each side, 

 rather spreading (or oblique in the nariow leaves), straight for more 

 than half their length or gently curved. Inflorescences geminate, from 

 the young branch-forks, dichotomously corymbose, many-flowered, more 

 or less pubescent (at least in the lower parts), or more rarely quite 

 glabrous; peduncle rather stout, 1-5 in. long; bracts ovate-oblong, 

 obtuse or subacute, up to 4 lin. long, caducous ; pedicels rather slender, 

 3-7 lin. long. Calyx subcampanulate, herbaceous, 3^-4^ lin. long, 

 with a transverse zone of numerous glands above the base, not or very 

 tardily circumscissile at the base ; lobes rotundate-ovate, obtuse, about 

 as long as the tube, at length often spreading or reflexed. Corolla 

 greenish-yellow ; tube stout, constricted at the middle and mouth, 

 twisted, 4-4J lin. long, very finely tomentose on and especially between 

 the filamental ridges, otherwise glabrous between them : lobes broad, 

 obovate to obovate- oblong, up to 7 lin. long. Stamens iiiserted above 

 the middle; anthers 2-2| lin. long, tips very shoitly txserted, tails 

 moderately long. Disc fleshy, annular, less than half the height of the 

 ovary. Style 2 lin. long. Berries (often one abortive) obovoid-glo-

K. Sciuimann states that the flowers of the plant, which he descrij^ed oripinally 

 as V. Boehmii, are white, and smell slightly like plue. Goetzo's plant, also named 

 V. Bishmii by K. Schumann, has according to the collector greenisli-yellow flower.*. 

 It agrees exactly with Kirk's specimens (from the district between Lupata and 

 Sena), of which there is a coloured sketch by Kirk, at Kew. showing the flowers to 

 be a pale greenish -yellow. The original V. Boehmii was collected in the Kawondi 

 district on the east shore of Lake Tanganyika.

 shape, size and tomentum, lanceolate to obovate, ovate or elliptic, ncute
