THE FLOWER. 49 



Questions upon the Buttercup (Fig. 60) and its 



Schedule.

 How is this stated in the schedule ? 

 Are the stamens free or adherent ?

 How is this expressed in the schedule ?

We have now reached the complete schedule of 

 Prof. Henslow, which he called the flower-schedule, 

 and which was used by his classes both at Cambridge 

 University and at his parish school at Hitcham. Corn-- 

 plaints have been made that it was difficult. Pupils 

 who commence its use before they fully understand 

 the features of plants to which it calls attention, will, 

 no doubt, get confused when they attempt to fill up 

 the blanks one after another, but those who have ex- 

 amined a variety of flowers, in connection with the 

 foregoing pages, will have no such trouble. 



The presence or absence of cohesion and adhe- 

 sion in flowers is of great importance in determining 

 the relationships of plants, and scholars cannot do 

 better than continue the use of this schedule through- 

 out the summer season, along with the making of 

 an herbarium. Do not fail to fill out schedules of 

 the following flowers, from your own observation. 

 Never write a word of description unless it be of 

 something your own eyes have seen, and that you 

 could point out to any one who might contradict you.
