NOTES ON THE GENUS FICU8 (TOUBN.), LINN. 
By Joseph Burtt-Davy, F.L.S., RE.S.S.Af., F.E.G.S. 
(With Plates XII., XIII.) 
(Bead October 18, 1911.) 
In the Keio Bulletin for 1908 (No. 4, p. 165) I discussed the relation- 
ship of the Wonderboom, as the result of studies in the herbaria of Kew 
and Zurich. At that time I was unable to arrive at any definite con- 
clusion, but subsequent study of the tree at different seasons and 
under varying conditions shows clearly that it is a distinct species, for 
which I propose the name of Ficus PretoricB. 
Ficus PretoricB, Burtt-Davy, sp. nov. — Arbor majuscula, umbrosa, 
ad 60 ped. alt., ramis patentibus in comam latiusculam expansis, ramulis

coriaceis, glabris, integerrimis, apice obtusis vel acutis, basi truncatis vel 
rotundatis vel vix sub-cordatis, petiolis eglandulosis 1-1-| poll, long., 
receptaculis tribus in axillis, densis, sub-globosis, glabris, verrucosis,

Vahl var australis Warb. non F. australis, Willd. 
Spreading, umbrageous, evergreen tree, up to 60 feet high ; branchlets
