FLORA ORCADENSIS, 
INTRODUCTORY. 
HE Science of Botany seeks to elucidate plant 
life in its various forms. The study of this 
science in its fullest sease embraces plant mor- 
phology, anatomy, physiology, ecology, palzobotany, 
pathology, and systematic botany. Only a few 
botanists bave been able to devote the time neces- 
sary to master all these branches of the subject. 
Many people study the subject as a hobby, and 
find it one of the most delightful and exhilarating 
of studies, as it takes its votaries far afield in the 
bracing air and sunshine of our heaths, moors, and 
sea-sides. In fact, the one branch of botany which 
suits the holiday excursionist is systematic botany. 
It classifies all plant life and elaborates schemes of 
relationship whereby the affinities of plants to one 
another are shown. The essential study in modern 
systematic botany is by a comparison of the pro- 
cesses of growth and development. We can thus 
arrange plants in groups according to aie apes
