including Ireland. In England only recorded as 

 a garden escape.] 



Saxifraga rotuudifolia, L. A native of the mountains 

 of Southern Europe, much cultivated in England, and 

 occasionally noticed as a garden stray. 



Saxifraga Sibthorpii, Boiss. Native of* Greece. 

 Mr. William Whitwell informs me that this species 

 has been sent to him from Tunbridge Wells, where it 

 was a garden weed. 



{Saxifraga tridactylites, L. This is one of the 

 species which is almost invariably relegated in local 

 Floras to artificial habitats such as walls. If these were 

 the only situations in which it was known in England 

 it should not be claimed as an undoubted native. As 

 a matter of fact, however, it is fairly common on dry 

 stony hills, though perhaps more often seen on walls 

 than anywhere else.] 



CRASSULACE^E. 



Cotyledon hispanica, L. A native of the Western 

 Mediterranean area. There is a specimen in the British 

 Museum Herbarium, collected near Oban, and pre- 

 sumably a garden escape. 



[Cotyledon lusitanica, Lam. Native of Southern 

 Europe. Recorded by Hudson from Somerset and 

 Yorkshire. This species must also be looked upon 

 as alien in the absence of confirmatory records.]
