LABIATE 153 



Xamium bifidum, Cyr. Native of woods in South- 

 East Europe and a weed of cornfields in the neigh- 

 bouring regions. Once recorded as growing plentifully 

 in a cornfield in Yorkshire. 



Lamimn intermedium, Fries. A weed of cultivated 

 ground in North-West Europe, including Northern 

 Britain and Northern Ireland. 



Lamilim laevigatum, DC. Native of the mountains 

 of Southern Europe. In Britain recorded as an escape 

 from gardens. 



Lamiimi maculatum, L. A native of woods from 

 Persia to Southern Belgium. Much cultivated in 

 Britain, and often found near gardens in a quasi- 

 naturalised state. 



Lamium purpureum, L. A weed of arable land, road- 

 sides, and waste ground over the whole of Europe, 

 Northern Africa, and Western Asia. It is difficult to 

 determine whether it is truly native in any part of 

 this area. No record can be found of its appearance 

 in any perfectly natural locality, at any rate in England. 



Leonurus Cardiaca, L. Not recorded in England, 

 except in the immediate neighbourhood of gardens 

 where it is cultivated. In Southern Europe it seems 

 less dependent upon actual cultivation, but nowhere 

 can a native record be found. 



Leonurus Marrubiastrum, L. A native of Eastern 

 Europe and Northern Asia. A casual in the neighbour- 

 hood of Hull Docks.
