Figure 2. Length Width Ratio. 



1. SCAMMELL — ratio greater than 2 



2. PIONEER — ratio 2 



3. JERSEY — ratio less than 2

Apex angle varies enough to be another important characteristic. It may be 

 narrow as in Cabot, medium as in Grover, or wide as in Jersey (Figure 3). 



.To establish classes of base angles, leaf bases were measured with a leaf gage 

 furnished by Clark (4). On the basis of the.se measurements varieties were 

 divided into four groups. Those having a base angle of 60°-70° are called narrow, 

 represented in Figure 3 by the variety No. 73; 70°-80° are medium, Wareham; 

 80°-90° wide, Pioneer; and over 90° ver>- wide, Jerse>-. 



The various types of leaf folding are very important. In some varieties such 

 as Sam the edges of the leaves curve back in such a way as to form a reverse
