In order to prevent confusion of nomenclature, I shall here 

 mention a few species of the neighbouring genera that have 

 been popularly confounded with the preceding. Of these the 

 first is the Moutarde blanche, Sinapis alba (White Mustard) ;* 

 it is cultivated in the Vosges, under the name of Navette 

 d'Ete, but can in nowise be confounded with the plant that 

 more generally bears this name ; the leaves are more deeply 

 divided, and have their lobes more indented, but, above all, 

 the seed-pod is short, hispid, and terminated with a kind of 

 depressed horn, in the shape of a dagger ; it contains but a 

 small quantity of seeds, and these are of a pale colour. It is 

 generally employed for making mustard, but as I before ob- 

 served, it is cultivated in some parts of France as an oleiferous 

 plant, under the name of Navette d' Ete, and sometimes it is 

 called Graine de Beurrc. 



The next is the Camelina saliva,^' which is likewise desig- 

 nated in some provinces by the names of Navette d'Ete, and 

 Graine de Beuwe ; in other places, from a curious confusion 

 of terms, it is called Camomille !; the Belgians name it Door; 

 the Alsacians, Dotterle ; the Germans, Dotter ; and the Ita- 

 lians, Dorella. Next to the true Colsa this is the most pro- 

 ductive among the oleiferous cruciferous plants, and is known 

 by the following distinctions ; its leaves are entire, and pro- 

 longed at their basis by little ear-like appendices ; its seed-
