A SUPPLEMENT 



TO THE 



"Flora of the North-East of Ireland" 



of Stewart and Corry. 



By S. A. STEWART, F.B.S.Edin., and R. LLOYD PRAEGER, B.E. 



IT is now within a few months of seven years since the Flora of the North - 

 East of Ireland was published, affording botanists a summary of our 

 knowledge of local topographical botany, and giving a general account of the 

 flora of the twelfth district of Oybele Hibermca. Since that time, considerable 

 progress has been made ; a goodly number of species have been added to the 

 flora, and our knowledge of the distribution of others has been augmented to a 

 noteworthy degree. Since the publication of Flora several papers have appeared 

 summarizing the more important additions, and others dealing with the botanical 

 characteristics of certain tracts of country, or with certain groups of plants 

 within our district. There have also appeared scattered notes on the local flora 

 in Journals, and Proceedings of Societies. Our present object has been to bring 

 all these together, along with a considerable amount of unpublished material, 

 and no pains have been spared to make this Supplement complete and trust- 

 worthy, by inviting the assistance of local botanists, by examining herbaria, and 

 published and unpublished matter not accessible formerly, and by carrying out 

 systematic field work in selected districts, and searches for plants whose local 

 status required investigation. 



Being a Supplement to the Flora of the North-East of Ireland, the present 

 paper divides itself into two sections : — (1) Plants or records to be removed 

 from the Flora ; and (2) plants or records to be added to the Flora. The former 

 category, we are glad to say, is soon disposed of. The following species must 

 be withdrawn from the list of native and naturalized plants, for the reasons 

 stated in the systematic list that follows : — 



Ononis spinosa. Calamintha officinalis. 



Rosa micrantha. Primula veris. 



Silaui pratentis.
