nervo primario valido, recto, apicem versus attenuato, exourrente ; nervis 
secundariis distinctis, fere prominentibus, subangulis 70-80° oricntibus

subrecto exeuntibus, ramosis ; reticulo valde evoluto. 
Obs. — This leaf one might consider, on only superficial examination, 
as having much likeness to that of Myrica lignitum and to that of the allied 
living M. cerifera, Linn. But on closer examination it becomes the more 
evident that it cannot belong to a Myrica , as its texture is rigid and coriaceous 
and its nervation shows all the properties of Quercns. The primary nerve is 
strong ; the secondary nerves being curved are rather strong ; the tertiary 
ones, diverging nearly at right angles, are branched and united to one another; 
the network, enlarged in Big. 15 a, agrees most with that of Quercus. 
The comparison of the fossil with the present species leads perceptibly 
to those of Asia with oblong or oblanceolate leaves, being narrowed to the 
petiole and coriaceous. Among these Quercus Hancei , Bentli., from the Isle 
of Hongkong, bears leaves, which show a nervation and other qualities very 
similar to the fossil, excepting that the base is less narrowed and the margin 
entire. 
Of the Quercus of the European Tertiary, Quercus Hamadryadum, 
Ung., Q. Orionis, Ileer, and Q. argute-serrata , Ileer, agree more or less 
with the Australian one here described, especially respecting the form and 
partly, also, the texture. But they differ by some peculiarities of the nerva- 
tion and by the teeth of the margin.

preceding ones, from which it is distinguished as follows : — The form is
