four others named above. It is not unlikely to be disco- 

 vered in some of the counties adjacent to those mentioned; 

 but not so very likely as to warrant an increase in the co- 

 mital estimate ; especially since it may have become ex- 

 tinct in Perthshire, except in that small detached portion 

 of the county, situate between Clackmannan and the Firth 

 of Forth, and thus being physically a part of Fifeshire ra- 

 ther than of Perthshire.

Native. Pascual. Included in Lowe's list of Orkney 

 plants, and was also reported to grow on the Pentland 

 Hills, Edinburgh ; but neither of these Scottish habitats 

 appears to have been verified. Possibly it may be suffi- 

 ciently general in the English counties to bring the true 

 census nearer to 50 than to 40 ; although the recorded 

 facts will not at present wari'ant the higher estimate. This 

 is by much the most frequent species of its order in the 

 county of Surrey, and probably the same holds true for 

 many of the southern counties ; and yet, with reference to 

 Britain in general, it must be classed among the rarer 

 plants of ouv island.
