GLEANINGS IN IRISH TOPOGRAPHICAL BOTANY. 

 By ROBERT LLOYD PRAEGER, B.A., B.E. 



[Eead March 16th, 1902.] 



Op the material contributed or collected for "Irish Topographical 

 Botany," a quantity of gleanings remain after the crop has been 

 gathered in. These consist mainly of two sorts — notes of varieties 

 and hybrids, and notes of aliens. Except where the infoi-mation 

 respecting species could be amplified by including records of their 

 varieties, or where alien species could be admitted as naturalized, 

 neither of these classes of records was included in the book referred 

 to. In now publishing a selection of these notes, I have kept " Cybele 

 Hibernica" before me, and have aimed mainly at giving such records 

 as are ;_supplementary to the information therein contained. Though 

 the bulk of the notes which follow are unpublished previously, I have 

 not hesitated to include records scattered through inaccessible publica- 

 tions ; and have sometimes given, in condensed form, all information 

 relating to a plant, whether published or unpublished, usually indi- 

 cating what matter is original. The notes are arranged under county 

 divisions, and records are quoted according to the rules adopted in 

 " Irish Topographical Botany." References to published papers are 

 given by means of the numbers prefixed to them in the same work ; 

 which is followed in other details of arrangement also. 



As regards the records for which I am responsible. The heavy 

 field work of 1896-1900 gave little opportunity for the study of 

 critical plants ; but in some genera, notably AlcJiemilla, Euphrasia^ 

 and Chara, large collections were made, and the distribution of segre- 

 gates and varieties in Ireland to a great extent ascertained. My best 

 thanks are due to the several critical botanists who devoted much 

 labour to the naming of the material collected — Mr. Arthur Bennett, 

 the late Prof. A. W. Bennett, Mr. G. C. Druce, Messrs. H. & J, Groves, 

 Rev. E. F. Linton, Rev. E. S. Marshall, • Rev. "W. Moyle Rogers, and 

 Mr. Frederick Townsend.
