BOTANY. 



Questions upon the Buttercup (fig- 1 94) and its Schedule. 

 Is the calyx free or adherent ? 

 How is this expressed in the schedule ? 

 Where is the corolla inserted ? 

 How is this stated in the schedule ? 

 Are the stamens free or adherent ? 

 Where are they inserted ? 

 How is this expressed in the schedule ? 

 Is the pistil free or adherent ? 

 How is this written in the schedule ? 

 This is the complete flower -schedule of Professor 

 Henslow, which was used by his classes both at Cam- 

 bridge University and at his parish school at Hitcham. 

 Complaints have been made that it is 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 examined a variety of 

 flowers, in connection with the 

 foregoing pages, will have no 

 such trouble. 



The presence or absence of 

 cohesion and adhesion in flowers 

 is of great importance in deter- 

 mining the relationships of plants, 

 and scholars can not do better 

 than continue the use of this 

 schedule throughout the sum- 

 mer season, along with the mak- 

 ing of an herbarium. Always 

 write from your own observation. 

 Never give 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. We give some further 

 examples of the use of the schedule in flowers of very un- 

 like structure.
