A LESSON ON BUTTERCUPS. 215 



This work, however, must also be pursued along other 

 lines out of doors. In all collecting of wild plants the 

 teacher should understand the importance of noting the 

 situation where found, the kind of substratum generally, as 

 well as the mere identification of the species. It is desirable 

 that he should recognise well defined " regions " such as 

 " wayside," " field," " moor," " wood," etc., and also the 

 kind of soil, sandy, clayey, etc., for plants, and that he 

 should record the plant under these headings. 



Pupils should be taught never to hand in a plant without 

 stating the kind of situation where found. From the lists 

 built up in this way, in course of time, " plant associations " 

 or groups of plants of the same type of habitat may be 

 drawn up. For detailed guidance with regard to studies 

 of this kind teachers should consult Plant Biology by 

 Cavers (University Tutorial Press).
