of the Genus Brassica. 183 



tlie flowers of a bright yellow, I suspect this name has arisen 

 from some confusion of nomenclature. 



Second Race. Brassica campestkis pabularia. 

 This second race of Field Cabbage is designated by Com- 

 meralt in the Memoirs of the Agricultural Society of Paris, 

 for 17S9, under the name of Chou afaucher. It is perfectly* 

 intermediate between the Colsa and Chou-navet, and there- 

 fore to be considered an hybrid between the two races; the 

 root is fusiform, slender as in the Colsa, but mucli longer, the 

 stalk is short, like that of the Chou-navet, but not so thick, 

 the radical leaves numerous, hispid on the edges, and on the 

 nerves underneatli ; they have a long petiole, and are lyre- 

 shaped ; the plant bears frequent cutting as food for cattle. 



Third Uace. Brassica campestris Napo-Brassica. 

 Chou-Navet. Navew. 



The third race of Field Cabbage is that of the Napo-Bras- 

 sica, Chou-Navet (Navew), easily distinguished from the two 

 former by its root being swelled into a tuber near the origin 

 of the stem. Duchesne and other authors have considered 

 this plant as belonging to the Brassica oleracea-, it is com- 

 monly confounded with the Chou-rave, Brassica oleracea Ccmlo- 

 Rapa, but it decidedly belongs to the Brassica campestris, its 

 young radical leaves being hispid in the same manner as iu 

 the Colsa : this race comprises two distinct varieties, the coin- 

 mo?i Chou-navet, and the Ruta-baga ; the latter name is fre- 

 quently given to sub-varieties of the former, which occasions 

 some confusion both among practitioners and those who write 

 on the subject. The real Chou-navet \, Brassica Napo-Bras- 

 sica communis, is known by its irregularly shaped root, which 

 is either red or white, but never yehow, thence forming two 

 sub- varieties : tlie white sub-variety, Chou-navet blanc, alba, 



* Mr. Morgan, in the paper before referred to (Horticultural Transac- 

 tions, vol. ii. page 315), has described four kinds of Winter Greens without 

 stems, and with fusiform roots, with whicii M. Dc Candollc does not appear 

 to be acquainted; their dwarf habits ally them to the Brassica campestris, 

 while other pro[)erties show their affinity to the Brassica oleracea uccphala 

 or tall Cabbages ; the first, however, nearly approaches the character of this 

 second race of the Brassica cawpeslri.;; whilst the three last will probably be 

 considered as of hybrid production between the two above-named species. 

 Their names as given by Mr. Morgan are, 1st. ICgyptian Kale, or Rabi Kale : 

 2d. liagged Jack ; 'M. Jerusalem Kale, and 4th. Buda Kale. — Sec. 



f 'I'lie ClioH-navct u little known in the English gardens, though not un- 

 conmion in French horticulture. When cultivated in (Jreat Britain its 

 proper designation is Tnrni|)-ro()te(l Cabbage, to distinguish it from the 

 Turnip Cabbage, or the C'Aoit-jY/ir of the French. — iVcr.
