INTRODUCTION. 



STEWART and Corry's /'lora of the North-East of Irtland was published 

 by the surviving editor, Samuel Alexander Stewart, in 1888. Itgaveforthe 

 first time a full account of the flora ot the home counties of the north-eastern 

 botanist (Down, Antrim and Londonderry). 



In ISilf) a fir.st Supplement to the Flora was published by S. A. Stewart and 

 R. Lloyd Praeger, in which a considerable number of additional species, and new 

 localities for rarer species, were given. 



The object of the present publication is two-fold. It forms a second Supple- 

 ment to tiie Flora, detailing the additional information relative to local plant 

 distribution that has accrued in the twenty-eight years which have elapsed since 

 the appearance of the tirst Supplemeut. And secondly it is designed to act as a 

 synopsis of our knowledge of the flora up to date. To effect this, all plants 

 which oc('ur in the district are included, and to the details of any additional in- 

 formation relative to each species which may have accrued since the issue of the 

 first Supplement, a reference is added to the page of the Flora or of the first 

 Supplement on which earlier information concerning the plant in question is to 

 be obtained. While the list of plants thus represents the whole Mora as at 

 present known, the reader, in order to obtain full information as to the distri- 

 bution of a species, must consult the Ftora and the tirst Supplement at the pages 

 named, in addition to noting the additional stations given. 



The ineparation of the present Supplement was entrusted by the Committee 

 of the Belfast Naturalists' Field Club to a Sub- Committee consisting of S. A. 

 Bennett, B.Sr., N. Carrothers, 11. Lloyd Praeger, D.Sc, A. W. Steliox. W. J. C. 

 Tomlinson, Rev. C. H. AYaddell, B.D., and Sylvanus Wear. The labour ot jire- 

 paring the manuscript from all existing material fell entirely on the last-named; 

 this task he carried to a successful close, and after a brief illness he died within a 

 week of its completion ; its thoroughness and accuracy are a fitting memorial of one 

 of the most careful and industrious of local workers, and one of the most helpful 

 and most modest of men. Death has been busy among the lanks of local botanists. 

 The present i)ublication enshrines the last work of Canon I,ett and Mr. Waddell, 

 both of whom did so much for h-ish botany, and also posthumous notes of W. J. 

 C. Tomlinson, Rev. S. A. Brenan, Mrs. Leebody and S. A. Stewart. Stewart's 

 later work was mainly published in the first Supplement in 189"), to which S. A. 

 Brenan, J. H. Davies, Miss Knowles, Mrs. Leebody, Canon Lett, R. Lloyd 

 Praeger, and C. 11. Waddell were also extensive contributors. Of those who 

 ■contributed in any material measure to the original Flora published in 1H88, 

 the present writer is the only one left alive.
