xlviii 



ABBREVIATIONS. 



I. II. m. &c. represent the months of flowering, viz. Jan., 

 Feb., March, &c. ; but they differ so much in different parts of 

 the kingdom that only an approximation to the true time can 

 be given. 



When the Initial letter of the generic name is prefixed to that 

 of a variety, it is intended to show that the author quoted con- 

 sidered it to be a species.
