Hably, Lilla: Egerian macroflora from the Andornaktálya sandpit (Hungary)

1963 Spirematospermum wetzleri (Heer) Chandler; Rüffle, p. 170, Pl. 2, Fig. 11; Pl. 17, Fig. 7. 1969 Spirematospermum wetzleri (Heer) Chandler; Knobloch, p. 48, 146, Pl. 13, Fig. 5; Pl. 57, Figs 5, 6. 1971 Spirematospermum wetzleri (Heer) Chandler; Bûzek, p. 91. 1978 Spirematospermum wetzleri (Heer) Chandler; Mai and Walther, p. 138, Pl. 48, Figs 14-18. 1985 Spirematospermum wetzleri (Heer) ('handler; Mai and Walther, p. 127, Pl. 31, Figs 33-35. Material: 89.532.1. Description: Fruit 7.0 cm long, 1.5 cm wide. Seeds 0.4-0.5 mm long, elongate. One end acute, another rounded. The species is very widespread from the Late Eocene to the Pliocene in Europe and Asia. There are a few unpublished Pannonian localities in Hungary. The Andornaktálya specimen from the sandy layers is the first find in the Hungarian Upper Oligocène. Spirematospermum wetzleri is a characteristic member of swamp vegetations. Monocotyledonae Material: 89.542.1. Description: Small, monocotyledonous leaf imprint; no characters except dense, parallel venation. FLORISTIC EVALUATION The Egerian flora of Andornaktálya contains a single species of Gymnospermatophyta phylum, a Tetraclinis salicornioides specimen. The flora mostly consists of the members of the phylum Angiospermatophyta. Dicotyledons are dominant, monocotyledons are very restricted. The Lauraceae family is the most widespread beyond any doubt, displaying the highest diversity, too. Clearly, these species lived under optimal conditions. Although Lauraceae dominate almost all Hungarian floras, their unusually high proportion at Andornaktálya is surprising. A special method for interpreting leaf floras has been developed by GREGOR (1982) for Neogenc floras. His method is applicable for Hungarian Egerian floras, too, since the Egerian and the older Neogene floras are very similar in morphology and species composition. GREGOR (1982) established 23 categories for leaf types, based on leaf margin, shape, laurophylous character, not completely free from taxonomic composition. The categories arc marked by letters from a to x. a = cinnamomoid i = quercoid r = typhoid b = lauroid k = tilioid s = smilacoid c = diospyroid 1 = populoid t = ginkgoid d = taxodicoid m = carpinoid u - comptonioid e = myricoid n = cornoid V = viscoid f = juglandoid o = rosoid w = pinoid g = aceroid p = salicoid x = palmoid h = leguminosoid q = hidrophytoid
