by HEER (1859, p. 93, Taf. 148, Fig. 11 -12), can also be relegated to this formgroup. SQUINABOL (1889, p. 57, Tav. 21, Fig. 2, andTav. 29, Fig. 7) published similar leaf remains under the name Palaeothalia sanctae justinae. BERGER(1950, p. 93) 1 mentioned the remain of „Musophyllum bohemicum UNG." from the Lower Pliocene near Vienna. There are some remains of a resembling type described as Cannophyllites, or Zingiberites. KNOWLTON (1923) relegated a rather similar leaf fragment to the genus Pontederites. REID & CHANDLER (1926, p. 85, Pt. 5, Figs. 8-9, and Figs. 10 — 11) connected similar leaf remains from the Bembridge flora with a number of recent genera of the family Zingiberaceae. On the leaves of Cannaceae, as remarked by BRONGNIART, the tertiary veins are no more to be seen. On the basis of epidermis studies, KRÄUSEL and WEYLAND (1954, p. 120) separated the genus Zingiberoideophyllum, then WEYLAND (1957, p. 68) established the new genus Scitamineophyllam by the epidermal structure of the fossil finds. ILYINSKAYA (1963, p. 174, Pt. 1, Fig. l,and PL 2, Fig. 1) separated leaves of a dissimilar character in the new genus Nitophyllites zaisanica of the family Podostemaceae, found in the Soviet Union (Kiin-Kerish, Zaisan Basin). On the Nitophyllites species, the primary secondary veins do not seem to be prominent. Comparison with recent species : The Ipolytarnóc leaf remains can be compared to the leaves of the recent Anadendron montanum (BL.) SCHOTT, and Anadendron latifolium HOOK. The scandent plants live in the whole Malayan Peninsula, in Borneo, Sumatra, Java, Celebes. They advance to about 700 m high up in the mountains. The remain illustrated on Plate VIII, Fig. 5, can also be compared with the incised leaf segments of Raphidophora korthalsii SCHOTT, and Raphidophora beccarii ENGL. Similar recent species are Raphidophora oblongifolia SCHOTT, also with a slightly asymmetrical leaf base, or Raphidophora hookeri SCHOTT, Raphidophora tonkinensis ENGL., and KRAUSE, of SE Asia. Morphologically similar leaves might also ne found in the genera Pothos, Scindapsus, and Epipremnum. CHANDLER (1963, p. 364) published Epipremnum and Raphidophora seeds from the Tertiary strata of England, and DOROFEEV (1958, p. 1104), from the Soviet Union. There are certain resemblances between the leaves oî Aglaonema cambodianum GAGNEP., and Aglaonema decurrens BUCHET, and the Ipolytarnóc remains. Also, the Aglaonema leaves are morphologically closely allied with those of Zingiber paradochelium WALL, and Zingiber clarkei KING. Araceites hungaricus sp. n. (Plate IX, Fig. 5) Diagnosis: A cylindrical spadix fragment. The measurable length of the incomplete spadix impression is 2.5 cm, width 1.2 cm. The spadix shows 3—4 mm Fig. 3.
