With this legume a small leaf, Pig. 29, has been found at Vegetable 
Creek, which, respecting form, texture, and nervation, most agrees with those 
of Podogonium leaflets. It is oblong, and scarcely narrowed at apex. The 
primary nerve is percurrent and prominent. The secondary nerves are 
numerous, fine, somewhat undulate, and the basilar ones diverging at more 
acute angles than the others. The tertiary nerves, being very fine and 
abbreviate, proceed at varying acute angles, and anastomose into a very 
tender hut slightly developed net, Pig. 29a, enlarged. 
The leaflet of Podogonium Knorrii which Heer has figured in his 
Tertiarflora der Schweiz (vol. Ill, PI. CXXXVI, fig. 2), exhibiting a rather 
protruded apex, agrees best with the above-described one. The latter is 
different from the former only by its secondary nerves being a little more 
distant. The basilar ones are barely twice as long as the others.

Obs. — The existence of the American genus Copaifera in the Tertiary 
Plora of Europe is proved by legumes and leaflets discovered in the Tertiary 
strata. It is very probable that this genus is present in the Tertiary Plora of 
Australia. There lie indeed only leaflets before us, upon which that pro- 
bability is based ; hut the leaflets of Copaifera are characterised by such 
striking features that at least the hitherto known living species may he safely 
distinguished from those of other genera. The fossil represented in Pig. 23 
corresponds almost perfectly to those of the Badobqj Plora, referred to a 
legumen of Copaifera and denominated C. radohojana by Unger (see Sylloge 
Plant. Poss., ii, PI. XI, figs. 4-9). Whilst the most minute-meshed network,
