7. V. lutescens, Stapf. A shrub, 9-1? ft. high; branches 
moderately stout, pallid, usually pubescent when young, rarely quite 
glabrous from the beginning. Leaves sessile, rarely subsessile, 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 narrow 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, 34-44 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, 444 lin. iong, 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 inserted above 
the middle; anthers 2-24 lin. long, tips very shoitly exserted, tails 
moderately long. Disc fleshy, annular, less than half the height of the 
ovary. Style 2 lin. long. Berries (often one abortive) obovoid-glo- 
bose, oblique, 2 in. long; pericarp thick, coriaceous when dry, mottled. 
Seeds coated with a thick pulpy mantle (aril? ), longitudinally grooved, 
grooves wide with transverse partitions; testa finely granular.

K. Schumann states that the flowers of the plant, which he described originally 
as V. Behmii, are white, and smell slightly like glue. Goetze’s plant, also named 
V. Beehmii by K. Schumann, has according to the collector greenish-yellow flowers. 
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 
€ a pale greenish-yellow. The original V. Behmii was collected in the Kawendi 
district on the east shore of Lake Tanganyika. 
8. V. africana, Stapf in Journ. Linn. Soc. xxx. 87 partly. A 
shrub or small tree, up to 15 ft. high; branches moderately stout, 
glabrous or pubescent when young, pallid. Leaves rather variable in 
Shape, size and tomentum, lanceolate to obovate, ovate or elliptic, acute 
to acuminate, rarely obtuse, long (rarely abruptly) attenuate towards and 
acute (rarely subcordate) at the base, 14-8 in. long, 1}-4} in. broad,
