PREFACE. vil 



various local floras would have occupied too much space, 

 besides which many of them are too unreliable. 



My thanks are due to the following gentlemen for 

 much valuable help : the Rev. W. A. Leighton, Mr. C. 

 B. Plo wright, the Rev. J. Stevenson, the Rev. Dr. Keith, 

 Professor James, W. H. Trail, and many others, besides 

 those already mentioned. 



As errors, in spite of all one's care, will creep into a 

 work of this kind, I shall take it as an act of kindness 

 on the part of those who will point them out, with the 

 view of correcting a second edition should it ever be 

 called for. 



WILLIAM PHILLIPS.
