Cornus View in CoL ” ferox UNGER

2004 “ Cornus ” ferox UNGER; Kovar-Eder et al., p. 84, pl. 12, figs 6, 7.

D e s c r i p t i o n. Leaf (?) sessile; lamina broadly obovate, l × w = 53 × 40 mm, base subcordate, apex rounded – (?) mucronate; margin entire; venation subpalmate, midvein stout, straight, basal lateral primaries 2 (–4, outermost very thin) arising from lamina base, forking; secondaries brochidodromous, delicate, very widely spaced, arising at very narrow angles, at first converging towards midvein, then distinctly turning towards the margin and bent towards it proximally (concave), forking once to several times near margin; intersecondaries present, forming elongated meshes; higher order venation not preserved.

Cotinus (?) aizoon (UNGER) KOVAR- EDER et KVAČEK Pl. 3, Figs 1–8

2004 Cotinus (?) aizoon (UNGER) KOVAR- EDER et KVAČEK; KovarEder et al., p. 80, pl. 11, figs 6, 8–10.

A d d i t i o n a l m a t e r i a l. GBA 2005/0004/0010 + 0011, 0012, 0014, 0071, 0075, 0086A + B (part and counterpart), IBUG 2018.

D e s c r i p t i o n. Leaves long-petiolate; lamina broadly obovate, l × w about 19–45 × 13–31 mm, ratio l/w about 1.2–1.5 (2), base cuneate, apex rounded, mucronate or slightly emarginate; margin entire; midvein straight, medium thick; secondaries brochidodromous/eucamptodromous, sometimes deeply forked, relatively dense; intersecondaries occasionally developed; tertiaries forming a polygonal network.

R e m a r k s. Hably (2020) noted that Cotinus sp. from the flora of the Mecsek region differs by a thicker petiole. The material described here from Parschlug also includes such a specimen (Pl. 3, Fig. 4). However, the specimen from Mecsek area differs from the Parschlug material by its larger size.

Differing from Dicotylophyllum sp. A by the reticulate (not percurrent) tertiaries.

Differing from Dicotylophyllum sp. B by the obovate shape, lower l/w ratio, denser and occasionally deeply forked secondaries.

Differing from Leguminophyllum sp. E by smaller blade, long petiole, obovate shape, denser and steeper secondaries.

Daphnogene polymorpha (A.BRAUN) ETTINGSH. Pl. 1, Fig. 13

2004 Daphnogene polymorpha (A.BRAUN) ETTINGSH ; KovarEder et al., p. 55, pl. 2, fig. 8.

A d d i t i o n a l m a t e r i a l. IBUG 1284 + 2827 (part + counterpart), 1285.

D e s c r i p t i o n. Leaves petiolate; lamina (broad) elliptic, l × w about 31–52 × 17–32 mm, ratio l/w about 1.5–1.8, base wide cuneate/convex, apex not preserved; margin entire; venation acrodromous; midvein straight to slightly bent, lateral primaries suprabasal, reaching well above the middle of the lamina, giving rise to numerous exmedial veinlets; lateral primaries looping with secondaries; secondaries brochidodromous, few, restricted to upper part of lamina, at wide angles; tertiaries thin, arising from midvein at almost right angle to wide angle, tertiaries between secondaries percurrent, higher order veins fine reticulate.

Differing from Dicotylophyllum sp. X by thicker primaries originating suprabasally and reaching the upper third of the lamina.
