 might be referred either to the Fringed or Palm Cabbage, 

 and tends to prove the diversities of character which unite 

 these varieties : as I have had no opportunity of seeing the 

 plant itself, I cannot class it with any degree of certainty. 



To these five varieties, which compose the race of Cava- 

 lier Cabbages, I shall add a sixth, which may in time, pro- 

 bably be found sufficiently distinct to form another race ; I 

 mean the Cabbage called Chou a grosses cotes, Brassica 

 costata, (Large-ribbed Cabbage). The authors who have 

 preceded me in the classification, either rank it among the 

 Cavaliers, or pronounce it to have more resemblance to this 

 race than to any other. Its distinguishing character is a 

 short stem, nearly single, with close leaves, but especially with 

 extremely * thick ribs ; it is also known in France under the 

 names of Chou de Beauvois, and Chou a larges cotes, and is 

 principally sown in village gardens, for the use of the family, 

 being very abundant in produce, though not very delicate in 

 flavour. 



While cultivating the Brassica costata, I have more than 

 once had occasion to observe a curious sub-variety, or dege- 

 neration of the kind; some of the plants emitted from the 

 back of their primary ribs a kind of appendage, similar in 

 consistency to the footstalk of the leaves ; these appendages 

 were of different sizes, and the largest dilating at its extremity 

 formed a concave disk resembling a cup or funnel. This 

 singularity recalling to mind the organization of a well known 



* The Core tronchuda, an open Cabbage, which has recently been introduced 

 into the Enghsh gardens from Portugal, and which has been found so excellent a 

 vegetable, nearly agrees with the above character and description of the Chou a 

 grosses cotes. Sec.
