APPENDIX II 461 



the field will, too, it is opined, stimulate the student to 

 endeavour to discover the relation of the plant to its environ- 

 ment, its requirements, and the functions of plants or their 

 organs ; and even to carry out experiments in physiology 

 relating to nutrition, growth, etc. 



This will naturally, it is probable, lead to a study of their 

 structure and form, or their morphology, and the con- 

 nection between these features and the functions of plants. 

 It may be carried as far as their external features, when 

 a study of the different organs and their meaning may be 

 made from the plants themselves in the field ; or even 

 extend to their internal features, and embrace a knowledge 

 of anatomy or histology demanding microscopical work. 

 These mastered, the more difficult problems of cytology and 

 embryology will come as a further inquiry in the realm of 

 the unseen, and here also microscopical work is involved to 

 make the invisible visible. Such work is generally not so 

 interesting to the majority of lay students, hence its place 

 in this plan is after enthusiasm has been securely obtained 

 and maintained by more general and less arduous work 

 at first. 



If the student, however, wishes to specialise in systematic 

 botany or taxonomic work, he will, having mastered the 

 types here described, next tackle the complete British flora 

 by degrees, supplementing the knowledge thus gained — 

 acquired only by much travel and long experience — by 

 acquainting himself with Continental floras in the field and 

 in the study. In this latter work much labour may be saved 

 by a knowledge of the special monographs and papers dealing 

 with individual genera and orders which are scattered 

 throughout the scientific journals of this country. A few 

 memoranda upon this subject are given. It must be 

 emphasised that in each case only a summary can here be 

 attempted, thougli this is more than most works attempt,
