It was collected in the “ interior of Africa ” by Vaillant. This description evidently 
refers to a totally different plant from WM. indica, var. 8, and to it belongs the 
synonym, Villarsia orbiculata, G. Don, Gen. Syst. iv. 169. Therefore, since the name 
L. orbiculatum, Griseb., belongs to one plant and the description under it to another, 
and as G. Don clearly perceived the difference between the two and gave the name 
Villarsia senegalensis to one of them, it appears advisable to discard the name LD. 
orbiculatum and retain that of L. senegalense for the preceding species.—N. FE. Br.

This may be the same as one of the species above described, but it is certainly 
not L. indicum, Griseb., which according to the type specimen at Kew is identical 
with Z. eristatum, Griseb., and has white flowers. I have not found a single 
instance in which the African and Indian plants of this genus belong to the same 
species.— NV. FE. Br.
