I. Beech, Chestnut, Wild Cherry, Birch, 

 Alder. Elm, Linden and Locust: Trees whose 

 slender and flexible ttjoigs hare alternate buds 

 and dark burl:. The twigs of these trees re- 

 semble one another closely and are more 

 difficult of recognition than all others. 



1. Beech (Fagus americana Sweet) . Beech 

 twigs are known by their unusually long and 

 .slender, pointed buds which have many over- 

 lapping scales (Fig. 56). The twigsare smooth 

 and reddish brown, and are bent at the points 

 of attachment of the buds. The tree is recog- 

 nized also by the clean and smooth gray bark 

 of the trunk. 



2. Chestnut (Castanea dentata Borkh.). 

 Chestnut twigs of recent growth have strong 

 ridges extending downward from the leaf scars 

 (Fig. 57). The rounded buds are light brown, 

 have few scales and extend from the twig at an 

 aneic of somewhat less than 45°. The bark of 

 the twigs and youngshoots is smooth and shin- 

 ing. The bark of the trunk is coarsely ridged 

 lengthwise. 



3. Wild Cherry or Black Cherry (Prunus 

 seroiina Ehrh.). The Wild Cherry has rigid- 

 looking steins which are flexible when bent but 

 which break when bent sharply. The small 



scaly and pointed buds hug the stems closely.
