the hill- sides ; yet we have no record of either of these forms having been 
found in any other locality in Ulster. 
In conclusion, we may say a few words as to the times at which the 
various observers, whose names occur in the following pages, lived and 
laboured in the cause of science. Mr. Templeton was the great pioneer 
°.f ."Ulster, botany, and the accuracy and care displayed in his notes have 
excited the admiration of all who have followed in his wake ; most of his 
records date between 1780 and 1810. After him came Messrs. Thompson, 
Whitla, and Hyndman (about 1820 to 1840), each of whom contributed his 
share towards the knowledge of our local flora. Other names which fre- 
quently occur in the “Flora of Ulster” (1864), from which we have extracted 
many notes, are those of Messrs. Ferguson, Millen, and Orr, and that of the 
author, Dr. Dickie. Following many of the localities in this list will be found 
the names of Dr. Mackay and Dr. Moore, each of whom did so much good 
work in the cause of Irish botany. More recent observers, whose names 
often occur in this list, are Messrs. S. A. Stewart, H. 0. Hart, and R. M. 
Barrington. After each locality we have given, as far as we were able, the 
name of the original finder; and where the plant has been since observed 
there we generally mention it.
