I. FAGUS L. 



Trees with smooth, close, ash-gray bark, and slender, often 

 horizontal, branches. Staminate flowers in long, slender-pedun- 

 cled, roundish clusters ; calyx bell-shaped, 4-6-cleft ; stamens 

 8-12 ; anthers 2-celled. Pistillate flowers solitary or more often 

 in pairs, peduncled, surrounded by a 4-lobed involucre and 

 numerous linear bracts ; ovaries 3-celled, ^ith 2 ovules in each 

 cell, but usually only 1 ovule maturing in each ovary ; styles 3, 

 thread-shaped. Fruit a thin-shelled, 3-angled nut.* 



1. F. grandifolia Ehrh. Beech. Large trees. Leaves oblong-ovate, 

 taper-pointed at the apex, serrate, straight-veined, very white-silky 

 when young, nearly smooth with age. Involucre densely covered with 

 short recurved spines. Nuts thin-shelled, edible. Common on damp 

 soil everywhere. The ■^^■ood is vei'y hard, tough, and close-graiued, 

 and is especially valuable for the manufacture of small tools.* 



2. F. sylvatica L. The Emopean beech is occasionally found 

 planted as a shade tree. The variety known as the copper beech 

 is most usual, and is readily recognized by its dark, crimson-purple 

 leaves.
