A d d i t i o n a l m a t e r i a l. GBA 1841/0001/0036 (bis), GBA 2005/0004/0065, 0066,? 0067, 0093, IBUG 874 + 875 (part and counterpart),? 12001.

D e s c r i p t i o n. Leaves long petiolate; lamina lanceolate, rarely somewhat ovate to obovate, l × w about 18–>80 × 5–20 (30) mm wide, ratio l/w about (2.5) 3–5.3, base wide to narrow cuneate to convex, non-decurrent, apex narrow acute to long acuminate; margin often entire in the lowermost part of the lamina, then regularly, sharply toothed; teeth slender, spine-like, partly s-shaped, in broader leaves shorter, sinuses rounded to narrow rounded; midvein stout, straight or slightly bent; secondaries craspedodromous, regularly spaced, in number corresponding with that of marginal teeth, originating at moderate to acute angles, running rather straight into the tooth apices, rarely forked; tertiaries very thin, percurrent, almost perpendicular to secondaries.

R e m a r k s. The assignment of the specimens figured on Pl. 9, Figs 17 and 18 remains ambiguous.

Differing from Dicotylophyllum sp. 5 , Dicotylophyllum sp. M and Myrica lignitum see those taxa.

Differing from Quercus zoroastri by the more slender shape of the lamina and more densely toothed leaf margin.
