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

Frankfurt a. Maine. MÄDLER also discussed a cone fragment. STAUB (1881) described the genus Libocedrus from the Aquitanian flora of the Fruska Gora. The remains of Libocedrus occur everywhere in the Tertiary floras of Radoboj, Bilin, etc. In Hungary, the impressions of the side-shoots of the flat branches are also frequent in the rhyolite tuff of Ipolytarnóc. Even a cone fragment was found in Ipolytarnóc. Comparison with recent species: Libocedrus macrolepis (KURZ) BENTH. = Heyderia formosana (FLORIN) LI, and Libocedrus formosana FLORIN = Heyderia formosana (FLORIN) LI might come into consideration when comparing the species with recent ones. The trees, attaining a height of even 50 m, grow on not too dry soils in the ranges of Formosa and Yunnan in SE Asia today. MALPIGHIACEAE Tetrapteris harpyarum UNG. (Plate I, Fig. 4) Description: While almost 20 specimens of this fruit were found in the Upper Eocene marl formation, there was only one in the clay sediment of the Middle Oligocène. The tetraalate fruit resembles the open wings of a butterfly and is identical in all respects with the specimens originating from the so-called Buda marl formation and discussed in an earlier paper of the author (RÁSKY 1956). ETTINGSHAUSEN^ (1872, Taf. 15, Fig. 6—11) Tetrapteris sagoriana specimen, published from the Tertiary flora of Sagor, seems to be identical with UNGER'S (1851, p. 176, Taf. 50, Fig. 8-10) Tetrapteris harpyarum. The Tetrapteris bilinica ETTINGSHAUSEN (1868, p. 23, Taf. 46, Fig. 10) and Tetrapteris minuta ETTINGSHAUSEN (1888, p. 341, Taf. 7, Fig. 10 — 11) specimens described from Leoben are dubious fragments and, being badly preserved, are not suitable for comparison. Comparison with recent species :As concerns recent species, most Tetrapteris species are lianas. The genus ranges in Mexico, the Western Indies, and from Bolivia to Southern Rrasil. The fossil remains can best be compared to the fruits of the recent tropical species Tetrapteris cordifolia MART., Tetrapteris maranthamensis A. Juss.,and Tetrapteris schiedeana CHAM. & SCHLECHT. EUPHORBIACEAE Balouhiaepbyllum mioeenicum (ETTH.) n, comb. (Plate I, Fig. 1) 1869. Baloghia miocenica ETTH. - Foss. Fl. Bilin, p. 45, Pl. 50, Fig. 22. Lectoholotype: the leaf shown on Plate I, Fig. 1. In the Paleobotanical Collection of the Botanical Department, Natural History Museum, Rudapest; Collect, nr. 62.62. 1.

Materials, impression of 4 leaves, lectoholotype, the counterpart, and 2 small leaf fragments. Diagnosis : Obovate leaves. Length of leaf lamina 10 cm, width 5,0 cm Leaf entire. Apex mucronate. Leaf gradually tapering but not elongated
