the Thames counties, which appear to be simply repeated 

 by modern authors, without confirmation afresh. Hudson 

 says that it is frequent in Lancashire ; where, however, I 

 am unaware that it has occurred to any now living bota- 

 nist. To these English provinces and counties, that of 

 " Galloway," or the West Lowlands, is added in the 

 British Flora, editions 4 and 5, without any personal au- 

 thority given for the locality. Lightfoot had previously 

 included it in the Flora Scotica, but without specifying any 

 habitat. It seems likely enough that the species will occur 

 in some of these provinces. . • - ^^^

Native. Sylvestral and Rupestral. Numerous localities 

 are reported for this species in England, where it grows 

 on the cliffs of the coast, as well as on banks and in bushy 

 places inland. The Scottish locaUties are something sus- 

 picious as native habitats. Professor Balfour sends me 

 specimens from Kirkcudbrightshire ; and Mr. Embleton, 

 also, from the banks of the White Adder, near Berwick on 

 Tweed. How far these localities are truly native habitats, 

 I am not prepared to say. The " debris of Salisbury 

 Craigs," near Edinburgh (where I found only L. latifolius),
