I give here also (compare § 9) the values of the means 

 and the dispersions : 



Breadth the of leaf: 



M = 14,03 ± 0,36 

 Ö = 4,38 ± 0,25 



(;:lf = 0,3i2. 



Length of the leaf : 



M== 35,52 ± 0,90 

 G = 11,1 1 ± 0,63 

 (7: il/ = 0,3 13. 



Hence we have 



breadth : length = 0,395. 



Certainly there are several biological conclusions to be 

 drawn from the different characteristics given above, I con- 

 sider it, however, most judicious to leave those conclusions 

 to the biologists.
