latter name is frequently 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* Bras- 

 ska Napo-Brassica communis, is known by its irregularly 

 shaped root, which is either red or white, but never yellow, 

 thence forming two sub-varieties : the white sub-variety, 

 Chou-navet blanc, alba, (White Navew), is sometimes mistaken 

 for a Ruta-baga ; the other is the Chou-navet a collet rouge, 

 purpurascens, (Red Navew.) 



The Ruta-baga, Napo-Brassica Ruta-baga, also called 

 Navet jaune, Navet de Suede, Chou de Laponie, and Chou de 

 Suede,"X has a root more regularly round or oval, and is 

 yellow both on the out and the inside. It is natural to suppose 

 that the race of Chou-navets proceeds from the Colsa crossed 

 by the Br assic a Rapa ; its characters are intermediate between 

 the two, and Mr. Sageret has found that among the hybrid 

 plants he had obtained from the Colsa, many were swelled 

 out at the lower part of their stem. Care must be taken 

 not to confound the Chou-navet, united by a hyphen, with the 

 Chou navet written as two distinct words ; the former is the 



* The Chou-navet is little known in the English gardens, though not un- 

 common in French horticulture. When cultivated in Great Britain its proper de 

 signation is Turnip-rooted Cabbage, to distinguish it from the Turnip Cabbage, 

 or the Chou-rave of the French. See. 



f The Ruta-baga is well known in Great Britain, in field cultivation, as the 

 Swedish Turnip; though of modern introduction, it is extensively grown. The 

 true and pure sort has yellow flesh and is without a stem, but it is apt to degene- 

 rate from both these important requisites to a good plant, either by the flesh 

 becoming white, or by the crown running up into a stem of more or less length. 

 It is remarkable that the yellow fleshed Swedish Turnip produces whitish flowers, 

 whilst the white fleshed bears dark yellow flowers. Sec.
