Populus latior A. BRAUN

Pl. 8, Figs 16, 17

2004 Populus populina (BRONGN.) ERW.KNOBLOCH ; Kovar-Eder et al., p. 70, pl. 8, fig. 18; pl. 14, fig. 1, nom. illeg., see Doweld (2017).

A d d i t i o n a l m a t e r i a l. GBA 2002/0001/0078, GBA 2005/0004/0084, 0125, IBUG 1233, NHMW 1878/6/7762, 7767, 7792, 9083.

D e s c r i p t i o n. Long-petiolate leaves; rather variable in shape, broadly oval to rounded to deltoidal, l × w about 13–77 × 15–77 mm, ratio l/w about 0.7–1, base truncate to widely cuneate, apex bluntly acute to acuminate; margin crenate-serrate, near the base often entire, teeth sometimes irregular, sinus rounded, apex blunt, indistinctly glandular; midvein straight; secondaries semicraspedodromous to craspedodromous, basal pair running at wide angles upwards towards margin, looping with higher secondaries or their branches near margin, sending regularly exmedial side veins towards basal margin; further secondaries at wide to moderate angles, in broader specimens curved, in deltoidal forms rather straight; tertiaries dense, (forked-)percurrent, more or less obtuse to midvein depending on position within lamina; quarternaries and higher order veins polygonal reticulate.

R e m a r k s. Doweld (2017) reidentified Populus latior A.BRAUN as the correct name instead of P. populina (BRONGN.) ERW.KNOBLOCH , which is an illegitimate homonym.

Prinsepia serra (UNGER) KOVAR- EDER et KVAČEK Pl. 8, Figs 20–24, Pl. 10, Fig. 15

2004 Prinsepia serra (UNGER) KOVAR- EDER et KVAČEK; KovarEder et al., p. 72, pl. 13, figs 9–17.

A d d i t i o n a l m a t e r i a l. IBUG 2059, NHMW 1878/6/7500, cf. 9119, cf. 9440, 9530, NHMW Ett. No. 660.

D e s c r i p t i o n. Long-petiolate leaves, petiole up to at least 18 mm; lamina rather variable in shape, elongated to roundish, l × w about (13) 20–90 × 12 to nearly 40 mm, ratio l/w about 0.9–3.6, leaf base cuneate to convex, often somewhat asymmetric, apex rarely preserved, narrow to broadly acute or emarginate; margin densely, but irregularly, serrate almost along whole leaf length, teeth irregularly sized, narrow triangular and sharp (narrow acute), sinuses acute or rounded; midvein stout, straight; secondaries semicraspedodromous, delicate, densely spaced, at moderate to wide angles, looping with sub-parallel intersecondaries, forming narrow elongated meshes near the leaf margin; side-veinlets arising from loops, some of them running into tooth apices; tertiaries and higher order venation reticulate.

R e m a r k s. The tertiary and higher order venation is reticulate (Pl. 10, Fig. 15); it is not exmedially ramified as suspected by Kovar-Eder et al. (2004). Specimen NHMW 1878/6/9119 is a rather large leaf and its margin is incompletely preserved. The venation is indicative of P. serra .

Differing from Dicotylophyllum sp. W see that taxon.

Differing from Ternstroemites pereger by the very variable, laminar shape, the usually larger size and lower l/w ratio, the dense, differently sized, triangular and sharp (narrow acute) marginal teeth lacking apical glands.
