408° FLORA NIGRITIANA. 
laciniis tamen acumine subulato 3-4 lin. longo terminatis. 
Annulus internus tubi e paleis brevibus reflexis constat. 
Stamina versus apicem tubi inserta, antheris ovato-oblongis 
connectivo acuminatis. Ovarium 5-loculare, ovulis solitariis 
pendulis. Stigma C. acutiflore. 
The Pachystigma venosum, Hochst., from South-east Africa, 
appears to be a third species of Cuviera, a genus which comes 
very near to Vangueria and Canthium, as well in inflorescence, 
zstivation, style and ovules, as in the curious ring of reflexed, 
often scaly hairs, in the tube of the corolla. 
The Ancylanthus rubiginosus, Desf., from Angola, is not 
among our collections. :

Ramuli pilis brevibus rufis hirti. Folia vix bipollicaria, ob-

As Vangueria and Canthium are only known from each other, 
when in flower, by the number of cells of the ovary, this plant 
must, in the absence of fruit, be referred to the former genu» 
although in habit it comes so very near to some Canthia. 
1. Canthium horizontale, Benth.—Phallaria horizontalis, Schum. 
et Thonn. Beskr. p. 112.—Cape Coast, Vogel ; Guinea. — 
, Although I have not seen Thonning’s specimens, bis descrip" 
tion indicates most clearly a Canthium, and Vogel’s single 
specimen, although in fruit only, agrees with it as far as it 
goes. Like the rest of the genus, the fruit is generally vey 
oblique, and reduced to a single cell, although occasionally # 
perfect didymous two-celled berry is met with.
