is also a characteristic inhabitant of sandy heath-borders and rough 

 banks in light soil"; and he adds : "I have little doubt that in such 

 situations it is native, and has spread thence into fields, etc." As 

 far as my acquaintance with the distribution of the genus Lamium 

 in Scotland extends, it supports Mr. Dunn's conclusions, except 

 that even L. Galeobdolon cannot be regarded as native in 

 Scotland, where it is rare even as an escape. L. album occurs not 

 uncommonly in the vice-counties (except 93, 97, 98, 100) as far 

 north as Inverness, though very rarely north of the Caledonian 

 Canal ; but it is restricted to waysides and hedges, near houses, and 

 where rubbish is thrown out. L. iiiaculatiini is an evident escape, 

 outcast, or relic of cultivation. L. purpureum occurs in every vice- 

 county ; L. amplexicaule in all except 97, 99, 102, 104, 112; L. 

 intermedium in all except 79, 81, 84, 86, 88, 97, 99, 104, 106, 

 107 ; and /. indsum (the least frequent of the four) in all except 

 72, 73, 74, 75, 79> 82 > 96, 97, 101, 103, 104, 105, 106, 107, 108, 

 109. All the four grow chiefly as weeds of cereal or root field- 

 crops, or in gardens, but they also grow on waste ground where 

 rubbish is thrown out, or on similar soil on the borders of fields, 

 especially in light soil. But though found in such uncultivated 

 ground, it is only, so far as I have seen, as extending to it from 

 cultivated ground, and not as natives of the uncultivated soil 

 invading the fields. There are good grounds, therefore, for regarding 

 all the species of the genus as either casuals, colonists, or aliens 

 within Scotland. JAMES W. H. TRAIL.
