pedition, without the exact locality, Vogel; Senegal. 
Vogel's specimens have smaller and more shining leaves than 
the Senegambian ones, but both appear to belong to one 
species, both agreeing with De Candolle’s characters, and having 
the young shoots compressed, the stipules narrow, rigid and 
acute, the cymes reduced to a head or umbel, either all but 
sessile, or borne on a peduncle about a line long. The fruit- 
bearing pedicels are from half an inch to an inch long, but 
from the remains of flowers, it is evident that they were much 
shorter at an earlier stage. The fruit is usually dimidiate, a& 
described by De Candolle, yet occasionally a perfect didymous 
one may be observed. 
The remaining W. Tropical African species of Canthium are: 
C. Cornelia, Cham. Schl., C. subcordatum, DC., and C. Sene- 
galense, A. Rich., (Plectronia hirsuta, DC.) from Senegambia ; 
C. Thonningii, (Phallaria spinosa, Schum. et Thonn.), irc 
Guinea, and two undescribed species in Heudelot’s Senegambian 
collection. 
The genus Canthium should without doubt be placed next to 
Vangueria and Cuviera, in the subtribe for which I have pro 
posed the name of Vanguieriee ; as a genus, it should probably 
include (as partly suggested by Arnott and others) Plecfron" 
Linn., Psydraz, Gertn., Dondisia, DC., Phallaria, Schum. & 
Thonn., Mitrastigma, Hary., Psilostema, Klotzsch., and 
cocca barbata, Forst. On the other hand, Kraussia, Harv» 
(Carpothalis, E. Mey.), referred to Canthium by Endlicher, 
is very different, both in the zstivation of the corolla and the 
form of the fruit. Mitriostigma, Hochst., again, differs stil 
more widely, being a Gardenieous genus, closely allied t° 
-Fernelia, notwithstanding the character assigned to it by
