A d d i t i o n a l m a t e r i a l. GBA 2005/0004/0095A, 0095B, IBUG 1208, 239 + 1843 (part + counterpart), 1844, 1847, NHMW 1878/6/6510 ( Cercidiphyllum crenatum sensu Kovar-Eder et al. 2004 ).

D e s c r i p t i o n. Petiolate leaves, petiole 6–8 mm long; lamina subcircular to widely oval, l × w about 20–42 × 15–33 mm, ratio l/w about 0.9–1.3 (1.7), base cordate to rounded, often slightly asymmetrical, apex rounded to acute (acuminate); margin entire to finely indistinctly crenulate; venation acrodromous; midvein straight, thin, lateral primaries sometimes diverging from the petiole below the lamina base, at moderate angles, running into the apical third of the lamina; higher secondaries delicate, widely spaced, looping with lateral primaries, higher order venation indistinct.

R e m a r k s. Foliage of Ziziphus closely resembles that of Paliurus ( Bůžek 1971) . Our assignment is supported by the record of fruits of P. favonii UNGER from Parschlug ( Kovar-Eder et al. 2004). Although P. favonii sporadically also occurs in the Mecsek area, Hably (2020) assigned similar but larger leaves to Ziziphus paradisiaca (UNGER) HEER. P. tiliifolius differs from Cercidiphyllum crenatum (UNGER) R.W.BR. by the almost entire margin and primaries often arising from below the lamina base.
