Acorns single and sessile, in the axils of fallen leaves ; 

 long ovoid, more or less cylindroid above, polished brown. 

 Cupule hemispherical, smooth, with small ovate, closely- 

 appressed scales. 



Cupule, even in flower, investing more 

 than half-way up. Acorn projecting 

 about \ to \ its length. 



Quercus coccinea, Wangenh. Scarlet Oak. Very like 

 Q. rubra in habit and foliage, but leaves more deeply 

 divided, and brighter scarlet in autumn. 



Acorn in a stalked and more urceolate cupiile, investing 

 the globoid-ovoid nut more than half-way up. 



OO Scales of cupule elongated and subulate, 

 more or less reflexed or spreading, giving 

 the cup a mossed appearance; acorn thin- 

 shelled, long and slender, rough. Aborted 

 seeds in the lower part of the acorn. 



Leaves hardly coriaceous, sinuate-lobed, 

 green both sides; buds fringed with 

 persistent stipules. 



Quercus Cerris, L. Turkey Oak, Mossy-cupped Oak 

 (Fig. 91). Fairly large tree, easily known by the subu- 

 late persistent stipules investing the buds and leaf-scars, 

 the pinnate angular-lobed leaves, and " mossy-cupped " 

 acorns. 



Male catkins about 7 8 cm. long, with very distant 

 flowers, on a tomentose axis. Perianth usually 4-partite, 

 tomentose outside, with 4 yellow hairy stamens. Pollen 

 ellipsoid-oblong, with 3 longitudinal furrows. Female 

 flowers sessile, and single or grouped in 2 4, on short, 

 thick, axillary peduncles, the bracts and ovaries grey- 

 tomentose ; stigmatic arms often 4, sessile and reflexed, 

 linear and pointed.
