the district, and of these 23 are found within the narrow limits of 

 the Ben Bulben mountain group. The marked alpine character of 

 the flora at moderate elevations on this isolated limestone mass is 

 the most salient feature in the botany of the district. There are 7 

 Hieracia and 3 peculiar species, one of the three, Saxifraga nivalis, 

 being the rarest of all the Irish alpine plants ; another, Arenaria 

 ciliata, finding on Ben Bulben its only station in the British Isles. 

 The rare orchid Sdbenaria intacta, also unknown in Great Britain, 

 reaches in this district its extreme northern Hmit for Europe.

Area, 3733 sq. miles. — Flora, 681 species and sub-species. 



Inland, save for a few miles of salt marsh along the estuary of the 

 Newry river in the south-east. A large district with diversified physi- 

 cal features. In the west and south-west, the Eme basin offers a wide- 

 spread and complex lake system, including Upper and Lower Lough 

 Erne, Lough Macnean, Lough Oughter, and Lough Gowna. In the 

 east, the south and south-west shores of Lough Neagh, belong to 

 the district. On the northern boundary are the Sperrin mountains, 

 with Sawel, 2240 feet; Meenai-d, 2061 feet; and Dart, 2040 feet; 

 but only the southern slopes of this range belong to the district. In 

 the south-west are Cuilceagh, 2188 feet; Tiltinbane, 1949 feet; and 

 SlievenakUla, 1793 feet. There is a large ai-ea of limestone in 

 Fei-managh, rising in many places to a height of about 1000 feet. 

 In spite of the large extent of the district and the diversity of its 

 siu'face, the flora is poor. Highland type plants number only 17; 

 there are 7 Hieracia and 5 peculiar species.
