Obs . — A remarkable fossil fruit, discovered by Mr. It. M. Johnston in 
the Derwent district of Tasmania, of which Dig. 4 shows a longitudinal view, 
and Fig. 5 a view of the base. It is an acutely oviform quadrilocular putamen, 
the surface of which is irregularly covered with numerous small depressions 
and intervening tubercles, and resembling more especially the quadrilocular 
fruit stones of Cordia. 
The fossil leaf, PI. V, fig. 3, from Itisdon, is so imperfectly preserved, 
it is true, that its form can only be guessed at, yet it shows some very 
peculiar characteristics by means of which the determination of the genus 
becomes more than approximate. The fragment is capable of being restored 
into a broad, obtuse, ovate or elliptical leaf. The thick margin indicates a 
remarkably stiff texture. The surface is distinctly covered with close and 
very small protuberances (see the enlargement of the venation Dig. 3 a). The 
midrib and the camptodromic secondary veins are very prominent. The 
latter are not approximate, and proceed a short distance up the margin, where 
they merge into the leaf net. The tertiary veins are connected, and almost 
transverse ; the reticulation is very fine, but, owing to the protuberances, not 
distinctly visible. 
The characters enumerated point to the genus Cordia, in which are 
found species with very similar leaves, for example C. Bossieri, De Cand., C. 
subopposita, De Cand., C. scncgalensis, Juss., C. dioica, Boj., C. JPerrottetii, 
De Cand., and others. 
From these facts the occurrence of the genus Cordia in the Tertiary 
Flora of Tasmania can scarcely be subject to doubt. In the present flora of 
this part of Australia the genus Cordia is not to be found, although a few 
species are met with in tropical Australia, having emigrated thither from the 
Monsoon regions of India.
