46 ALIEN FLORA OF BRITAIN 



of some parts of South-East Europe. It is owing to the 

 latter habitat that it has so often been recorded in 

 connection with grain-siftings and in cultivated fields 

 in Britain. 



Malva parviflora, L. Native of dry, sandy, and rocky 

 ground in the Mediterranean region, and a weed of 

 cultivated ground in Central and Southern Europe. In 

 its numerous recorded British localities it can usually be 

 traced to grain introduction. 



Malva rotundifolia, L. A common waste ground 

 plant of England and the rest of Europe, but nowhere 

 in this area recorded from natural habitats. Aitchison 

 found it " everywhere among stones " in the Karrum 

 valley in Afghanistan, and it is very probably one of the 

 native plants of Central Asia which have advanced west- 

 wards with man. 



Malva sylvestris, L. A native of bushy places and 

 pastures in most parts of Europe, but becoming more 

 and more confined to artificial habitats north-westwards- 

 in Europe, and in England not recorded in natural 

 habitats, though common on roadsides and about 

 houses. 



Malva verticillata, L. It is probably a native of 

 China where it is frequent also as a weed of cultivated 

 and waste ground. In Europe it has long been culti- 

 vated, especially the variety crlspa, for various purposes, 

 and in England has been recorded once or twice as aa 

 escape from gardens. 



Wissadula spicata, Presl. One of the introductions.
