and the west of France. Mr. E. S. Marshall tells me 

 that he has seen it also in open copses in Kent. It is, 

 however, more frequent in Britain as a weed of cultivated 

 ground or as a garden escape. 



CARYOPHYLLACE^. 



Arenaria balearica, L. Native of the Balearic Isles. 

 It has long been cultivated in English gardens, and 

 is occasionally found established on walls in their 

 neighbourhood. 



Arenaria montana, L. A native of Western France 

 which has been recorded as an introduction in England, 

 being pro|pably of garden origin. 



Cerastium arvense, L. Native in elevated pastures 

 from Switzerland to South-East Russia. Further north 

 and west it appears to be confined to roadsides 

 and cultivated fields. In Britain it is fairly general in 

 such situations. Such are the majority of book records, 

 but particular attention should be paid by local botanists 

 to the exact localities of this beautiful species. It occurs 

 in the turf on the borders of downs, and old permanent 

 pastures, but, in any of these situations which I have 

 been able to examine, the species has always shown 

 undoubted signs of being a survival of former 

 agriculture. 



derastiuin dichotomum, L. A weed of cultivation in 

 the Mediterranean area. Communicated by Mr. Eraser 

 Robinson among casuals from Hull.
