86. GRAMINA. 163 



Native or Colonist. Agrestal. Common in the south 

 of England, decreasing northward, and under much sus- 

 picion of having heen introduced into the six or eight 

 Scottish counties, where it has been found of late years. 

 The EngUsh botanists (Lightfoot and Hooker) who wrote 

 Scottish Floras, after a very brief examination of Scotland, 

 enumerate A. agrestis among the native plants, without 

 expressing doubt of its nativity there, or giving any loca- 

 lities ; a course from which the fair inference would be 

 (or should be) that they had found the species widely 

 spread and frequent in Scotland. Nevertheless, it may 

 be doubted, without much presumption of injustice to 

 those Authors, whether either of them had ever seen a 

 Scottish example of the species, unless by chance and 

 rarely in some sown field.

 of Lobel's quoted station, " a few miles from Lee, Essex", 

 I have given the distribution above as if restricted to the 

 one local habitat. The plant now gi'ows at Guillon Links, 

 Haddington ; but is said to have been sown there at
