4 On the different Species, fyc. of the Genus Brassica. 



glaucous bloom, and glabrous from their first appearance, 

 somewhat fleshy, not actually scolloped, but sinuated to the 

 midrib, the lower leaves not excepted. It bears a strong re- 

 semblance to the Brassica Cretica, and the Brassica cam- 

 pestris ; but the former has a ligneous stalk, and the early 

 shoots and young leaves of the latter are covered with 

 bristles. It differs also from the Brassica Rapa, which has 

 hispid leaves, without glaucous bloom ; and from the Bras- 

 sica Napus, and Brassica prcecox^ the radical leaves of both 

 which are pinnatifid, or lyre-shaped. 



First Race* Brassica oleracea sylvestris. 

 Chou Saiwage. Wild Cabbage. 

 From universal testimony, this Cabbage is a native of. Eu- 

 rope ; it is mentioned by DioscoRiDES/f as an inhabitant of 

 Greece, and SibthorpI expressly says, that he found it wild 

 on rocks near the sea shore of that country. M. Bosc 

 assures us, that it still grows wild on the coasts of France. 

 M. Bouchet found it near Abbeville, on the hilly shores of 

 Treport ; and I remember, likewise, to have seen a few irre- 

 gular plants on the elevated coasts of Normandy ; in England,^ 

 it is found more plentifully in Yorkshire, Wales, Cornwall, 



* The Professor has used the terms Race, Variety, and Sub-variety, to enable 

 him more distinctly to class and divide what may be considered the Botanical 

 varieties of each species. Each Race comprehends one class of variation, and is 

 divided and subdivided into what he here terms Varieties and Sub-varieties. Sec.
