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. 



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



Acorn smooth, cup hemispherical, with 

 Jimbriated 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, Jim- 

 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.
