The samples with 9 leaves were too few to allow a de- 

 termination of the values of M and g. 



b) Regarding the length of each leaf in the rosule I have 

 examined 55 samples with 5 leaves and 38 samples with 6 

 leaves in the rosule. In the tables beneath I denotes the 

 mean-value of each class in millimeters.
