Obs . — This leaf reminds one of the Cinchonidium leaves of the Fossil 
Floras of Sagor and Bilin. As regards its characters, it approximates especially 
the leaves of C. mucronatum, Ett., and C. coprosmcefolium, Ett. It is, how- 
ever, distinguished from both in its thicker coriaceous texture and the 
smaller number of more acute-angled secondary veins. It has a more 
prominent spinule, and more distant, more bent, and forwardly ascending 
secondary veins than the C. mucronatum , which it otherwise resembles. It 
has, further, a shorter petiole, and is more narrowed towards the base than 
C. coprosmcefolium , with which it agrees best as regards the form and size 
of the leaf, as well as the characters of the secondary veins. Among the 
North American Tertiary plants, the Cinchonidium Copeanum, Lesq.,sp.,* may 
be mentioned as approximating the described Australian species. 
Among leaves of existing Rubiacecc , I find the leaves of Coprosma 
cuspidifolia, Be Cand., from Australia (see Ettingshausen, Blattskelete der 
Dicotyledonen PI. XXI Y, fig. 8), which are likewise provided with a strong 
spinule, so closely corresponding to the described fossil in texture, form, and 
venation, that I have no hesitation whatever in including it under the genus 
Coprosma itself.

The leaf described by Lesquereux as Diospyros Copeana, in tlie work quoted (p. 232, PI. XL, fig. 11), has 
less resemblance to a leaf of Diospyros than with leaves of the Cinchonacece, especially those of Cinchonidium 
bilinicum, Ett. (Foss. Flora von Bilin, vol. ii, PI. XXXV, figs. 28-31). As regards the form of leaf and the 
venation, the leaf referred to agrees perfectly with the leaves of the species named. It only differs in its some- 
what stronger texture and the shorter petiole. As a matter of fact, no Cinchonacete have as yet been discovered 
in the Tertiary Flora of North America ; yet it appears probable that representatives of the family were included 
therein, inasmuch as Cinchonaceae have been traced even in the Tertiary Flora of Europe, and the proper home 
of the family is at present America.
