•delay has been rather advantageous than otherwise, since it has 

 enabled us with the ready help of some valued correspondents to 

 secure much further information, the need of which became apparent 

 only as the work went on. 



In the first place, our thanks are due to Miss Frances M. More, 

 lor unwearied assistance in the preparation of this new edition. A 

 botanist of no mean attainments herself, she has been able to give 

 us material help in the examination of her brother's books, manu- 

 scripts, and correspondence^ while her general acq[uaintance with 

 his views has qualified her to make many suggestions of which we 

 have not been slow to profit. For much additional information, as 

 to the range of plants in north-east Ireland, and for aid in clearing 

 up many obscure points in the botanical literature relating to that 

 district, we are indebted to Mr. S. A. Stewart, of Belfast, who has 

 at all times most cheerfully placed at our disposal his wide and 

 accurate knowledge of the northern flora. Plant lists kiiidly pre- 

 pared for us by Mrs. Leelody, of Londonderry, have been of much 

 service in extending the known northern range of many species. At 

 the opposite extremity of the island, in south-west Cork, valuable 

 Assistance has been rendered us by a competent botanist, Mr. R. A. 

 Phillips, who has earned our warmest thanks by the unfailing zeal 

 and courtesy with which he has followed up the many troublesome 

 inquiries we have asked him to undertake. In the west. Miss 

 M. F. Jaelcson, of Lisloughrey, Cong, has kindly supplied us 

 with lists of plants observed chiefly round the head of Lough 

 Corrib, and with some notes on current L-ish plant-names. The 

 labour of consultiag and extracting from the earlier and less 

 accessible works on the Irish flora has been lightened for us by 

 Mr. C. B. Moffafs friendly aid ; the Rev. Wm. Colgcm, of Inveran, 

 lar-Connaught, has helped us in the determination of current Irish 

 plant-names ; Mr. F. W. Moore, Director of the Grlasndvia Botanic 

 Gardens, has freely placed at our disposal the manuscripts and 

 specimens of his father, the late Dr. David Moore ; Br. E. P. Wright, 

 Professor of Botany in Trinity College, Dublin, has kindly given us 

 facility of access to his botanical library, and supplied us with many 

 interesting references to specimens preserved in the extensive
