 Local. Frequent. Native or denizen. Rupestral. 



Very abundant in the lowlands, less frequent in the uplands, 

 but occurs all over the county. Its status needs investigation ; its 

 present position as an alien being apparently based (i) on a careless 

 interpretation of Dillenius's account of its escape from the Chelsea 

 garden (Why shouki not a native plant escape from a London 

 garden ?) ; and (2) on Watson's somewhat irrelevant and not quite 

 correct generalisations — (a) that the species occurs only on walls, and 

 {h) that it is injured by frost. The plant grows in masses sometimes 

 yards across, on an old pebble ridge at the Leys, in company with 

 two rupestral natives — Ceterach officinarum and Asplenium Ruta- 

 muraria, and is quite able to withstand the winters of South Wales, 

 as well as those of places much further North. 



I 147. FZIatine, Alill. Sharp-leaved FlueUin. Trwyn y llo blaenfeinddail.
