THE SUBDIVISION OF IRELAND kv 



ting to the botanist. In the south there is much poor stony country, 

 with large bogs and numerous eskers. The entire eastern boundary 

 is formed by the Shannon, including the whole western shore of 

 Lough Eee. In the north is a group of beautiful lakes, of which 

 Lough Key belongs wholly, and Loughs Arrow, Allen, and Gara 

 partly, to Eoscommon. Many smaller lakes lie in the centre and 

 NE. The Suck, a considerable stream, bounds the county in the 

 SW. No less than 98 per cent, of the surface is below 500 feet 

 elevation ; 59 per cent, is under grass, 20 per cent, crops, 12 per 

 cent, turf bog. The Lough Eee shores alone had been explored 

 when " Topographical Botany " was undertaken. Most of the 

 county has now been roughly, but no part thoroughly examined. 



Flora 544 species, of which the Lough Eee shores contribute 

 many of the more interesting. Eare or characteristic plants very 

 few : — 



Teucrium Scordium, 7. Carex axillaris, 4. Chara tomentosa, 5. 



26. Mayo East. 



West-central. Area about 778 square miles. A rather bare and 

 inhospitable stretch of limestone, broken only by a few minor patches 

 of non- calcareous rocks. Surface generally nearly level, with much 

 poor pasture, bog, marsh, and esker. Broad ridges rise in several 

 places to from 700 to 850 feet, but only slightly affect the flora. 

 In the extreme NW., the western extremity of the granite range of 

 the Ox Mountains gives a few elevations of 1200 feet, and brings in 

 a number of calcifuge plants. In the SW. the boundary passes 

 through the great lakes of Mask and Corrib ; the beautiful Lough 

 Carra, which adjoins, belongs wholly to this division, and a number 

 of small lakes also occur. There are no large rivers, the most 

 considerable being the Moy, which drains the northern portion. 

 Grass land covers 59 per cent, of the surface, crops 18 per cent., 

 turf bog as much as 11 per cent. ; 97 per cent, of this area is below 

 600 feet elevation. 



The flora of this extensive area was almost unknown till Messrs. 

 Marshall and Shoolbred published the results of their work at 

 Clonbur. The full lists with which Mr. Marshall has supplied 

 me have been supplemented by my own work, so that the flora is
