36 The Irish Naturalist. 



It will be observed that many of the records here collected 

 have already appeared in various publications. The principal 

 increase to the County Down flora is due to the exhaustive 

 paper on the Mourne Mountain flora by Stewart and Praeger, 

 in the Proceedings of the Royal Irish Academy 1 . A number 

 of notes from the Proceedings of the Belfast Naturalists' Field 

 Club have been availed of; and the pages of the Irish 

 Naturalist and of the Journal oj Botany also contribute valu- 

 able information. 



To the various naturalists whose names appear as con- 

 tributors in the succeeding pages I am deeply indebted. It is 

 due to their kind co-operation that this paper, condensed as 

 it is, has assumed such goodly proportions. 



The contractions used for authorities are — S. and P. — Stewart 

 and Praeger, op. cit. ; R. 1,1. P. — R. L,loyd Praeger ; S. A. S. — 

 Samuel A. Stewart. 



LIST OF RECORDS.

 reports it as abundant in the lough further to the west, at Derryadd Bay,

 the north-east. The plant does not seem to have been previously found 

 north of the Liffey.
