Trees; a handbook of forest-botany for the woodlands and the laboratory . etween two lobes, and mayfork over it. The basal secondaries sometimes come off asif primaries and palmate. [The var. monogyna is said to have the leaves bluishbelow and the secondaries more divergent.] ** Leaves oblong or obovate-oblong in out-line ; not tomentose beneath; pinnatelyand more or less sinuate-lobed, withdistinctly pinnate venation, the lowersecondaries shorter than those in midleaf. t Lobes more or less rounded, slightly mucro-nate or acute, but not acuminate or drawnout to long points or teeth. © Lobes rather angular, acute or mucronate, often separated by toide and rather deepsinuses, and themselves cut; leaf-base notauricled; stipules persistent on the leaf-bases and round the buds; surface roughwith stellate or tufted hairs. Quercus Cerris, L. Turkey Oak (Fig. 67). Large tree, with persistent setaceous stipules surrounding the buds. 14—2 212 TURKEY OAK Leaves 5—7 x 2—4 (8—18 x 2—9) cm., narrow-oblong oroblong-obovate and broadest near the middle, attenuated. Fig. 67. Turkey Oak, Quercus Cerris, p. 211 (Sc). or slightly cordate but not auricled at the base, obtuse;lobes rather narrow, rounded triangular, the middle incisednearly half-way, otherwise shallow, mucronate, rarely cut. OAKS 213 There is however much variation in the lobing, from largenearly serrate teeth to coarse sinuate, and occasionallynearly pinnatipartite segments; and leaves on suckers maybe large and hairy. Deep dull green above, glabrous exceptfor a few tufts of hairs; paler beneath and slightly velvetywith stellate hairs, hardly hoary. Petiole short, 3—20 mm.Stipules long, setaceous, curved and tomentose, persistenton the leaf-bases. Autumn leaves russet-brown to dull whitish grey.In young trees the dead leaves may remain on the twigsthrough the winter. Venation reddish, pinnate as in Q. Robnr; the second-aries about eight pairs. © © Lobes obtuse, rounded; stipules not per-sistent round the bu
