6 The Flora of Glamorgan. 



When a species is common and abundant, this paragraph will 

 be omitted as superfluous. Rare and critical species will 

 receive special attention — the localities in which they occur 

 will be fully quoted, together with the authorities for the 

 records. The Secretaries are mainly responsible for this citation. 

 Upon them has devolved the work of collating the reports of the 

 corresponding members. The sign of certainty (!) indicates 

 that a specimen has been seen by the Editor, and when the sign 

 is affixed to a locality, in that locality. 



The double sign (! !) indicates that the record has been 

 confirmed by Mr. A. Bennett, F.L.S., of Croydon. Much of the 

 value attached to the records of the more critical forms is due 

 to the untiring and constant help afforded to the Editor and 

 Secretaries by this most distinguished and expert student of the 

 British Flora. It is noteworthy that the specimens of the 

 Cardiff Museum Herbarium have all been submitted to him for 

 revision of the nomenclature, and that collection has now there- 

 fore a very special value for local botanists. The sign (?) 

 implies suspicion or doubt of the accuracy of the record. 



The Editor is responsible for most of the critical notes ; some 

 of these are written in the first person, others have Ed. appended 

 to them, but most of them are inserted without any special 

 indication of their origin. 



A complete list of all printed papers and books dealing with 

 the Flora of Glamorgan will, it is hoped, be added at the end 

 of the work. The following is a list of the abbreviations used 

 for the more important of them consulted in the compilation 

 of the first part.
