Rásky, K.: Tertiary plant remains from Hungary (Upper Eocene and Middle Oligocene)

Materials: impression and counterpart shown on Plate V, Figs. 1 — 2, and 3 further fragmentary specimens. Remarks : Remains similar to Scolopiaephyllum protoluzonense had been described by BERRY under the names Celastrophyllum cassinoides BERRY (1925, p. 65, Pt. 12, Fig. 11) and Celastrophyllum perryi BERRY (1925, p. 65, Pt. 12, Fig. 12) in the flora of the Bipley formation (Upper Cretaceous), but the configuration of the secondary venation differs from those of the Scolopia leaves. KNOWLTON lists a frequently occuring leaf as Zizyphus longifolia NEWBERRY from the flora of the Green Biver formation of the Middle Eocene (KNOWLTON, 1923, p. 169, Pt. 40, Fig. 7), whose type is similar to the leaves of Scolopia protoluzonensis, but, owing to the narrower lamina, denser dentation, and different secondary vena­tion, one cannot associate them. The leaves of Scolopiaephyllum protoluzonense are already known from Hungary, from the fossil flora of Ipolytarnóc (BÁSKY, 1959. p. 457, Pt. 70, Fig. 9). Comparison with recent species: The fossil leaf remains can favourably be compared with those of the recent Scolopia luzonensis (PRESL.) WARB. Today, they are small trees or shrubs on the islands of SE Asia, on the Philippines, Borneo and Celebes. The genus Scolopia inhabits also Africa and Australia, ranging preponderantly in tropical areas, thriving in the plains or the lower mountainous ranges, but some species occur also in subtropical zones. They grow r alike in clayey soils, on sandy beaches, or on limestone. Banara eoeeniea BERRY (Plate V, Figs. 5-6) Description: Leaves elongate-oval. Base expanded or cuneate. Apex blunt. Margins approximately parallel with each other and midrib, with rare dentation at irregular distances. Teeth blunt, with spines remaining on some places only. Teeth present also on slightly asymmetric base. Measurable length of leaf 7,5—8,0 cm; actual length could have been slightly greater. Width of leaves 3,5—4,0 cm. Midrib thick. First pair of basal secondary veins, originating beside midrib, extending upwards; other laterals emitted higher. Number of secondaries 4 — 5 pairs, connected by great arches, camptodrome, emitted alter­nating from midrib. Basal secondaries bordered by smaller camptodrome veins in front of margin. Tertiary veins creating large-spaced polygonal venation, filled with minutely meshed reticulation. Short and minute veins excurrent from smaller camptodrome arches into teeth. Materials: 6 fossil leaves were found, none of them completely un­injured. One was retained together with its counterpart. B e m a r k s: The leaf remains are easily identifiable as the species Banara eocenica described by BERRY (1930, p. 110, Pt. 45, Fig. 17) from the Wilcox flora of the Lower Eocene. BERRY noted that the midrib is slightly bent on the Wilkox specimen, a feature well recognizable also on the Óbuda spécimen (Pt. V, Fig. 6). Fossil Banara leaves are known from South America and the North Ameri­can Wilcox group of the Lower Eocene flora (Puryear, Tenn.) ENGELHARDT pub­lished a leaf remain as Banara sp. from the Lower Miocene of Chile (ENGELHARDT, 1891, p. 667, Pt. 8, Figs. 2,4); BERRY from the Miocene of Patagonia, as Banara sp. (BERRY, 1925, p. 220, Pt. 6, Fig. 1), and from the Paleocene formations of Patagonia as Banaraphyllum ovatum (BERRY, 1937, p. 46, Pt. 9, Fig.l). Comparison with recent species: BERRY compared the fossil leaves with those to the recent species Banara reticulata GRIESEBACH (Bahama island) and Banara vanderbiltii URBAN (Porto Rico).
