"^"^/F^ M^/«o/r OH the different Species, Races, and Varieties 

 of the Oenus Brassica (Cabbage), cmd of the Genera allied 

 to It, 'which are cidtivated in Europe. By M. Augustin 

 Pyramus De Candolle, Professor of B'otanv in the Aca- 

 demy of Geneva, 3,-c. Sfc. 



[Concluded from p. 99.] 



Second Specjes. BRASSICA CAMPESTRIS. 

 TJNDER the name of Chou dcs champs. Field Cabbage, I 



compreheiul all those that have blue and glabrous leaves 

 at an advanced period of their growth, like the Brassica olera- 

 cca, and han-y leaves in the young plants, like the Brassica 

 Jiapaj they may be considered in this respect as intermediate 

 between the former and the latter. The Brassica campcstris is 

 nidigenous to Europe, and spoken of by botanists as o-rowing 

 spontaneously in fields in England* and Scotland, in Goth- 

 land, ni the southern part of Lapland, in Spain near Madrid, 

 m Iransylvania, and in the Crimea; but we must observe, 

 that where wild plants are found growing in the vicinity of the 

 very grounds in which the same plant is cultivated, there al- 

 ways remains some doubt as to the origin of die wild one, it 

 being natural to suppose that it proceeded from the cultivated 

 plant m its neighbourhood, and more particularly as they 

 scarcely ever differ from each other. 



First Race. Brassica campestris oleifera. 

 Chou oleifere. Colsat or Colsa, sometimes written Colza. 

 The plant which I here designate as being the Field Cab- 

 bage in its natural state, or very little altered by cultivation, 

 has a slender root, an upright, smooth, and branching stem' 

 about a foot and a half or two feet high, which, together with 

 the foliage, is covered with glaucous bloom, the interior part 

 ot the leaves of the young plants, as well as their edges and 

 nerves, are covered with bristles ; when older, all the leaves 

 are smooth, the lower ones are petiolated and shaped in the 

 form of a lyre : that is, their inferior lobes are separated as 

 far as the mid-rib and the superior ones united; the stem 

 leaves are bent inwards, embracing the stalk ; they are scol- 

 loped at their.basis in the shape of a heart, oblong, and entire 

 at the edges ; the flowers are constantly yellow, the leaves of 

 the calyx are half expanded, the seed-pods are upright, round, 

 perfectly tetragonal, swollen in a slight degree, and terminated 

 ni a point, which is nearly (|iiadrangular at its base; the seeds 

 are brown, abundant, and tolerably large. This plant is cul-
