Rásky, K.: Studies of Tertiary plant remains from Hungary

from Greenland is a synonym of Comptonia diforme (STERNB.) BERRY. ANDREÁNSZKY (1955) and PÁLFALVY (1951) described a similar leaf remain from ths environs of Eger, North Hungary. It cannot be doubted that the leaf remains of Comptonia sehrankii (STERNB.) BERRY, which had been known already from the Tertiary and the Cretaceous in Europe (with all of its synonyms) are not dissimilar to the American forms relegated by BERRY to the Comptonia diforme (STERNB.) BERRY form group. Sometimes it is extremely difficult to delimit them. Nor does the leaf remain of Comptonia hesperia BERRY differ much from the above species. Also, the form groups of Comptonia sehrankii and Comptonia diforme are closely connected with Myrica (Comptonia

) naumanii (NATHORST) HUZIOKAfrom the Early (?) to Middle Miocene and Early Pliocene of Japan. Comparison with recentspecies: The leaf remains of Comptonia sehrankii (STERNB.) BERRY are as well comparable to the leaves of the recent Comntonia aspleniifolia BANKS as to those of Myrica (Comptonia) naumanni (NATHORST) HUZIOKA from Japan. Comptonia aspleniifolia BANKS lives today in the NE United States. The blades found in the Rupelian clay of Budapest - Óbuda can be satisfactorily compared to the recent Comptonia aspleniifolia BANKS. KNOBLOCH connected the leaf and fruit remains of Comptonia diforme (STERNB.) BERRY, described from Czechoslovakia, also with the recent North American Comptonia peregrina L. Engelhardtia brongniarti SAPORTA (Plate VII, Fig. 5) Description : The involucre is small and trilobate. The lateral wings are shorter, the median one longer. The length of the central wing, together with the fruit, is 5 cm, the lateral ones 2.5—3 cm. The wings of the fruit markedly display the midrib and the two laterally decurrent 2 secondaries. The midrib and the secondaries are connected by tertiary veins. The wings are nearly equilateral and direct upward. Nucellus of medium size, ovate, 0.5 cm long. Remarks: The winged fruit is well comparable to the Upper Eocene fruits described in an earlier paper (RÁSKY, 1956, p. 169, Taf. 27, Fig. 1). The wings found in the Rupelian clay are considerably longer than those described from the Upper Eocene. For the sake of comparison, we submit now also two smaller impressions from the marl layer of Buda (Plate VII, Figs. 6—7). KRÄUSEL (1939, p. 40, Taf. 5, Figs. 3—6, and Textfig. 9) published Engelhardtia brongniarti fruits from the Aquitanian flora of Mainz

Kastel; STAUB (1885, p. 233, and 1886, p. (66—67) from the Tertiary of Freck (Felek), Roumania. WEYLAND (1937, Taf. 10, Figs. 12—13) separated the shorter and the wider winged fruits (with rounded apices) under the name Engelhardtia schlickumi. BERRY reported large-sized fruits, under the names Engelhardtia (Oreomunnea) mississippiensis (1916, p. 183, Pt. 17, Fig. 1), and Engelhardtia puryearensis (1916, p. 185, Pt. 17, Fig. 7) from the Wilcox flora. REID & CHANDLER (1926, p. 87, Pt. 6, Figs. 1—6) described larger fruits under the name Engelhardtia macroptera from the Bembridge flora. Tha size of these large fruits is not attained by those described by Unger from the fossil flora of Sotzka, of which the specimen on Taf. 32, Fig. 4 best resembles the impression found in the Rupelian clay from Hungary. Comparison with recent species: The European occurrences of this fossil fruit are now generally relegated to the recent species Engelhardtia serrata BL. On the other hand, SAPORTA'S Engelhardtia serotina resembPs the recent Engelhardtia spicatavav. colebrookeana (LINDL.) O.KTZE. GRANGEON (1958, Pt. 26, Fig. 13) described a fruit under the name Engelhardtia äff. wallichiana LINDL, from France. The species Engelhardtia mississippiensis BERRY is compared to the recent Engelhardtia oreamunoa (OERST.) DC. living in Costa Rica. REID & CHANDLER compared the Bembridge specimens with the fruits of the recent Engelhardtia spicata Lech, ex BL., and Engelhardtia nudiflora HOOK ( = E. serrata BL.).' Kydia palaeocalycina RÁSKY (Textfig. 5) Remarks: There were found fragmentary and badly preserved specimens in the Rupslian layer of the Kiscell clay; they are similar to the leaf remains of Kydia palaeocalycina RÁSKY (1956, p. 178, Pt. 32, Fig. 1) described from the Upper
