PREFACE. ix 
some of the more commonly employed alternative terms applied 
to particular organs’ have been added in brackets after those 
adopted in this work, so as to assist the student in correlating them 
correctly. 
The account of the Cycadacee calls for a word of explanation. 
It was hoped that this might have been prepared by Sir W. T. 
Thiselton-Dyer, F.R.S. Circumstances have unfortunately frus- 
trated the hope that his exact and extensive knowledge and his 
practised judgment in dealing with the members of this interesting 
and important order could be utilised in full. The work, none the 
less, is still largely his. The material in the herbarium at Kew, 
on which the account here printed is mainly based, has been arranged 
and annotated by him with such care and critical insight that the 
task of preparing that account has involved little more than the 
drafting of co-ordinated descriptions of the various genera and 
species.
