The species was described by ANDREÁNSZKY (1955) from the Eger-Wind's Brickyard section, where it is frequently found in the upper flora. It has not been found on other Upper Oligocène floras of Hungary as yet. As we have only a fragmented single specimen here, and the characteristic basal parts are missing, we cannot unambiguously state the presence of C. macrophylla in the Vértesszőlös assemblage. Fabaceae Leguminosae I. Pl. XXVIII, Fig. 2. Material: No.: 76.10.1. 1 piece Description: The basis of the leaf is missing; thus we can only estimate its length, approx. 9 cm. The width of the leaf is 4.5 cm. The margin is en­tire, the apex is emarginate, the basis is missing. The state of preservation of the leaf is poor, the veins of the second­ary order are visible only at some parts: they are thin, set at relatively great distance from each other, running till the margin of the leaf. The form of the leaf is oblong, on the medial phase of the leaf the margins are nearly parallel to each other along a longer phase. The leaves with emarginate apex found .in the Lower Oligocène were mainly described under the name of Dalber- gia bella . These leaves, however, are considerably differing from this speci­men­! The leaves of D. bella found in the Tard Clay do not exceed 5 cm, their shape is obovate, the basis is considerably narrow. There were several leguminose fruits found in the flora, supporting con­siderably the presence of the family, however, we could establish no direct connection between the fruits and the leaf, all the more because several oth­er remnants of leaves were found in the flora that could be equally associat­ed with these fruits. Legumi nosa e II. Fig. nr. Material: No.: 76.263.1. 1 piece Description: The apical and basal parts of the leaf are missing, the me­dial part is intact. The lamina is narrow oblong-lorate . The margins of the leaf are parallel to each other throughout the complete medial fragment, probably narrowing towards the apex and the basis. The margin is entire. The midvein is apparent, the secondary vein system is much more weaker. The camp­todromous character of the venation is still fairly well observable. The se­condary veins branching off the midvein flatly, getting thinner at the bend, and the loop can be observed only by the help of microscope already. The measurable length of the fragment is hardly reaching 4 cm, anyway, it could be probably essentially longer because there is no sign of either of the ends getting narrow as yet. The width of the lamina is 1.3 cm. Similar small, camptodromous veined leaves are most frequently encoun­tered under the name of Sophora in palaeobotanical literature. These remains are, however, though similar in size and venation, not so long. Their shape is much rather ovate or elliptic. Most features in common were observed with the species Sophora multifor­ mis described from the Tertiary flora of Alaska by HOLLICK (1936). Opposed to the rest of the Sophora species, the leaves of this species are elongated, their form is oblong, and the venation is camptodromous. The length of the leaves varies between 1.8-7.5 cm, their width is 1.75-5 cm. There were no more remains found of this type in the Vértesszőlös flora, at least none of the reminiscent forms were in adequate state of preservation for assignment. Remains of Sophora from Hungary are known mainly from the Miocene, in the first place, the Sarmatian period.
