It is possible that more than one species may be here con- 
founded, although I.am unable to distinguish them in the 
dried specimens. 
1. Geophila reniformis, Cham. et Schlecht. DC. Prod. 4. p. 587; 
var. ? foliis obtusissimis retusisve, —On the Nun, Vogel ; St. 
Thomas, Don. 
The leaves are more deserving of the epithet reniform, than 
the generality of the South American specimens, yet as far as 
the specimens go, they do not show any other distinctive 
character. 
2. Geophila hirsuta, Benth. ; foliis cordato-ovatis oblongisve 
acutiusculis utrinque ad venas petiolisque hirsutis, pedunculis 
abbreviatis, (bracteis subulatis.?).—On the Nun River, Vogel. 
Affinis G. violacee, sed folia superiora angustiora, tota planta 
siccitate nigrescit et multo hirsutior est quam unquam vidi 
varietates G. violacee. -Calycis lacinie pilis longis ciliatz. - 
Specimina flores paucissimos ferunt. Planta, teste Vogelio, 
dioica est. 
A third species, near G. reniformis, with remarkable broad 
bractew, is in Heudelot’s Senegambian collection. "das 
4. Octodon füifolium, Thonn., DC. Prod. 4. p. 540.—On the 
Quorra, Vogel ; Senegal and Guinea. 
1. Borreria Kohautiana, Cham. et Schlecht., DC. Prod. 4- P-
