country much before the beginning of the nine- 

 teenth century, and not recorded at all generally, 

 as a spontaneous plant, before the middle of the cen- 

 tury. It has increased very rapidly, by what means 

 has not been satisfactorily explained, and it is now 

 scattered all over England, even on heaths and sandy 

 banks, far from cultivation. In sandy cultivated 

 ground it is sometimes an abundant and troublesome 

 weed. 



Claytonia sibirica, L. A native of moist shady 

 places in North America which has long been 

 cultivated in British gardens. It frequently becomes 

 spontaneous in places where it has been planted, and 

 it has been recorded also from woods and parks in 

 various parts of England and Scotland. The records 

 are usually accompanied by notes as to the probability 

 of garden origin. Its distant foreign range and recent 

 appearance in this country must brand it in all its 

 stations as an introduction. 



Fortulaca oleracea, L. This universal weed of warm 

 countries has been found as a casual in England. 



FRANKENIACE^. 



Prankenia pulvendenta, L. A native of sandy 

 shores in the Eastern Mediterranean area which was 

 recorded by Hudson from the coast of Sussex. It 

 is quite possible that it was introduced there with 

 ballast.
