Obs . — The leaf fossil, Fig. 3, lias the character of Apocynaccous 
leaves, namely, of species of Taberncemontana, Aspidosperma, Allamanda , 
&c. It shows a somewhat coriaceous texture, a lanceolate, entire form, 
narrowed at both ends, a short petiole, and a camptodromic venation. The 
midrib is very prominent only at the base, and sends forth on either side at 
slightly acute angles several simple secondary veins, which towards the 
margin are bent slightly forward, equi-distant, and gradually shortened 
towards both ends. The tertiary veins have been preserved in one place 
only, are very fine, and issuing from the outer side at acute angles. No 
reticulation can he seen. 
The characters mentioned are met with almost entirely in the leaves of 
species of Taberncemontana (see Ettingsliausen, Blattskelete dor Dicotyledoncn, 
Plate XXIX, figs. 1, I and 8). Those leaves show also a slightly developed 
fine reticulation, which in a fossil condition might easily disappear. It is 
therefore extremely probable that the fossil from Dalton, just described, 
belongs to Taberncemontana. 
As an analogous and representative species from the European Tertiary 
Flora we may regard Taberncemontana bohemia , Ett., from the Fossil Flora 
of Bilin. As an analogous species in the present flora, I regard the T. 
laurifolia , L., from Jamaica. 
Locality and Horizon. — Dalton, near Gunning ; in hard siliceous 
grit, reposing on Silurian rocks. 
Eciiitonium ouscunrw, sp. nov. 
Plate IV, Fig. 10. 
Sp. Char. — E. foliis ovatis (?) coriaceis, integerrimis ; nervatione 
brocliidodroma ; nervo primario valido, recto excurrente ; nervis secundariis 
prominentibus subangulis 75-85° orientibus, valde arcuatis, laqueos margini 
approximates ; nervis tertiariis baud conspicuis. 
Obs . — In the Miocene strata of Badoboj and Leoben there occur 
seeds which are characterised by a long tuft of hairs. They belong to the 
Apocynacese, and have been referred by Unger to the fossil genus Eciiitonium. 
Together with these seeds in the strata of Leoben I found leaves, which 
have the habit of Apocynaceous leaves, and must belong to the seeds in 
question. These leaves are coriaceous, ovate or broadly elliptical, entire, and
