Celastrophylltjm Cunninghami, sp. non. 
Plate VI, Fig. 5. 
Sp. Clian. — C. foliis submembranaceis, ovalis (?) dentatis ; nervatione 
camptodroma; nervo primario distincto recto, secundariis approximatis, sub- 
angulis 60-65° orientibus, tenuibus simplicibus vel furcatis ; nervis tertiariis 
angulis acutis, egredientibus, tenuissimis dictyodromis. 
Ohs . — This fossil is too imperfectly preserved to admit of a definite 
determination of its form. But from the contraction of the area of the leaf 
at the lower end, we may suppose that it was ovate at the base. It also 
appears that the apex could not have been far distant from the line of fracture 
at the upper end, so that the form of the leaf must have been ovate or 
elliptical, rather than oblong or lanceolate. The margin is distinctly visible 
in one place only, and shows small approximate teeth, which have not left 
shallow impressions at cither their sinuses or their apices. This circumstance, 
as well as the feeble midrib, indicates a more delicate texture. The characters 
adduced and the venation, of which Pig. 5a is an enlargement, point to the 
order of Celastrinem, in which similar small dentate leaves often occur, as, 
for example, in Maylenus Loaria (Ettingsliausen, Nervation der Celastrineen, 
Denksch. K. Akad. Wissenscli. Wien, vol. xiii, PI. IV, figs. 4-6), Evonymus 
anicricanus (Ettingsliausen, loc. cit, PI. VIII, figs. 6, 7), and several others. 
The Cclastrineoe are abundantly represented in the Tertiary Plora of 
Europe, and among them the Eoonymus Latonice, Ung., the Celastrus 
oxyphyllus, Ung., and the C. JEoli , Ett., approach the Australian Celastrinese 
in some respects, although their leaves have a stronger texture. As the genus 
to which the described fossil belongs cannot at present be ascertained, and 
may possibly have become extinct, I have preferred to place it in the 
collective genus Celastrophyllum. 
I named the species after the English botanist, Allan Cunningham, 
who, fifty years ago, made important exploratory journeys towards the interior 
of Australia.
