PREFACE. 



The object of this work is to supply students and field-botanists with a 

 fuller account of the Flowering Plants and Vascular Cryptogams of the 

 British Islands than the manuals hitherto in use aim at giving. 



For the plants regarded as composing the British Flora proper, I have

 introduced have less claims than some they have rejected, but this 

 applies to very few cases indeed. 



The Ordinal, Generic, and Specific characters are to a great extent 

 original, and drawn from living or dried specimens or both. After work-

 of the descriptions in which work I cannot speak in terms of too high 

 praise. By this method of re-description, whilst I believe I have avoided 

 some errors of my predecessors, I have no doubt made others of my own ; 

 such creep into all endeavours to describe most or all of the organs of
