papery, glabrous or softly pubescent beneath, especially on the midrib; 
secondary nerves 11-16 on each side, subhorizontal or oblique, gently 
curved ; petiole up to 6 lin. long or hardly any. Inflorescences usually 
paired from the young branch-forks, dichotomously corymbose, many- 
flowered, glabrous or more or less pubescent in the lower part ; peduncle 
2-5 in. long ; bracts oblong, up to + lin. long, caducous ; pedicels slender, 
upto 10 lin. long. Calyx subcampanulate, 34-44 lin. long, with a trans- 
verse zone of very numerous glands above the base; lobes rotundate- 
ovate, as long as or almost as long as the tube. Corolla white, sweet- 
scented ; tube 3-44 lin. long, stout, constricted at the middle and mouth, 
twisted, finely tomentose on the filamental ridges, otherwise glabrous 
within ; lobes subobliquely obovate-oblong, from 6 lin. to almost 1 in. 
long. Stamens inserted above the middle; anthers 2 lin. long, tips 
shortly exserted, tails long. Disc annular, surrounding the ovary to 
half its height. Style 2 lin. long. Fruit unknown.—V/. glabra, K.

A specimen collected near Yaunde in the Cameroons, by Zenker & Staudt (121!), 
and distributed as V. Schweinfurthii, probably also belongsto V. africana, although 
the corolla-tube is almost 6 lin. long. All the Senegambia and Sierra Leone specr 
mens have more or less hairy leaves and peduncles; the same is the case with 
Barter’s specimens trom Nupe, and Mann’s from Fernando Po. The amount of 
hairiness varies considerably, and in Skues’ specimen from the Gambia, the youngest 
and smallest leaves are quite glabrous, whilst the larger lower ones have pubescent 
midribs. In a similar way, the Leopoldville specimen, collected by Dewévre, has 
glabrous leaves, whilst that gathered by Laurent has pubescent branchlets 8” 
leaves. I originally took V. africana in a very wide sense (Journ. Linn. Soc. ai 
87); but renewed examination, additional material and collector’s notes convince 
me that I had gone too far. 
9. V. chalotiana, Pierre MS. Quite glabrous. Branches rather 
slender, pallid. Leaves oblong to oblong-lanceolate, more or less abruptly 
acuminate, acute at the base, 3}—4 in. long, 14-14 in. broad, chartaceous, 
dull green above, brown beneath when dry; secondary nerves up to 2 
on each side, almost straight, rather spreading; petiole very slender, 
up to 1 in. long. Inflorescences geminate from the young branch-forks, 
dichotomously or trichotomously corymbiform, loose, many-flowered ; 
peduncles rather slender, up to 2 in. long; bracts caducous ; pedicels 
very slender, up to 8 lin. long. Calyx campanulate, about 3 lin. long;
