OAKS: HAZEL: BEECH 111 



with an expanded base in the shallow cup ; it is pale 

 brown, longitudinally striated, smooth as are the scales 

 of the cupule. That of Q. coccinea is very similar. 



7~7 l~~l Cupule-scales long, narrow, spreading, and 

 hairy. 



Acorn smooth, cup hemispherical, with 

 fimbriated scales. 



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

 (Fig. 106). 



Acorn velvety, half submerged in the 

 conical cup. 



Quercus Suber, L. Cork Oak (Fig. 105). 



Cupule tubular of foliaceous aspect, fim- 

 briated at the free margins, which project 

 beyond the top of the enclosed nut. 



Corylus Avellana, L. Hazel (Fig. 107). The Hazel- 

 nut has a hard woody shell, and exhibits traces of the 

 fused perigone margin near the apex : it occasionally 

 contains 2 kernels, but as a rule one of the two ovules 

 aborts. 



ft Cupule closed above until maturity, then 

 opening by 4 valves and disclosing 2 3 

 more or less angular nuts. 



Nuts 2, sharply trigonal; cupule stiff, 

 almost woody, covered with soft blunt 

 prickles. 



Fagus sylvatica, L. Beech (Figs. 108, 109). Each nut 

 is about 12*5 mm. long and shows traces of perigone and 

 stigmas at the apex, and is shining, smooth, brown, with 

 a triangular scar of attachment. As a rule it contains 

 only one seed, in which the cotyledons and first leaves 

 are peculiarly folded; the other two chambers and 5 

 ovules being aborted.
