canal banks, and such-like places, particularly in the 

 neighbourhood of large towns, and readily becoming 

 naturalised. 



Lepidium graminifolimn, L. Native in a few spots 

 in the Mediterranean region on dry pasture land, 

 and a common waste ground plant of the greater 

 part of Central and Southern Europe and Northern 

 Asia. Once recorded among grain-sifting aliens in 

 England. 



[Lepidium hirtum, Sm. Native in France and Spain 

 in pastures, on sandy heaths, and on rocks. There seem 

 to be no definite records of it in natural localities in 

 Britain, its usual stated habitats being roadsides and 

 waste places, but from its appearance in many districts 

 of Southern England, for instance on Dartmoor in 

 Devonshire, there can be little doubt that its native 

 range extends at least as far north as this.] 



Lepidium lacerum, C. A. Mey. Native of stony 

 ground in Persia and Central Asia. It has once been 

 recorded as a wool introduction in England. 



[Lepidium latifolium, L. The species ranges from 

 Western Europe and Northern Africa to Siberia. There 

 can be little doubt that it is native in some parts of 

 the coast of Britain, where it has long been known in 

 wild habitats, but in most of its localities it must be 

 admitted to be a relic of cultivation (for it was once 

 widely grown in gardens), its long creeping roots 

 rendering it capable of surviving for some time when 

 once planted.]
