52 ENGLISH BOTANY, 



disk resembling a flattened ring divided into segments by transverse 

 imjiressed lines. 



With A. Anglica I am unacquainted except from the specimens 

 contained in the Smithian Herbarium, where there are two wild 

 specimens from Sunderland, and a cultivated one from Mr. Robson's 

 garden — the latter scarcely differing from the normal state of 

 A. arvensis. The wild specimens have the clinanth convex at matu- 

 rity, the palea3 project between the florets and are rather more 

 pointed than in the var. a ; the pericline is more woolly ; the leaves 

 ai'e much less divided, but not dotted, as erroneously described by 

 Smith. I have sjiccimens of var. a from Crookston, Edinburgh, 

 which have the leaf-segments short and fleshy, approaching those 

 of the so-called A. Anglica.
