1. BRASSICA, CABBAGE, MUSTARD, &c. (Ancient Latin name of 

 Cabbage. Botanically the Mustards rank in the same genus.) (5) ® Cult, 

 from Eu., or i-un wild as weeds ; known by their j-ellow flowers, beak-pointed 

 pods, and globose seeds, the cotyledons wrapped round the radicle. 



B. olevkaeai, Cabbage. The original is a sea-coast plant of Europe, with 

 thick and hard stem, and pretty large pale yellow floivers ; the leaves very gla- 

 brous and glaucous ; upper ones entire, clasping the stem, not auriclo'd at the 

 base : cult, as a biennial, the rounded, thick, and fleshy, strongly veined leaves 

 collect into a head the first year upon the summit of a short and stout stem. 



— Var. Broccoli is a state in which the stem divides into short fleshy branches, 

 bearing clusters of abortive flower-buds. — Var. Cauliflower has the nour- 

 ishing matter mainly concentrated in short imperfect flower-branches, collected 

 into a flat head. — v ar. Kohlrabi has the nourishing matter accumulated in 

 tlio stem, which forms a turnip-like enlafgement above ground, beneath the 

 cluster of leaves. — Kale is more nearly the natural state of the species, the 

 fleshy leaves not forming a head. - 



B. camp^stris, of the Old World ; like the last, but with brighter flowers ; 

 the lower leaves pinnatifid or divided and rough with stiff hairs, and the upper 

 auricled at the base, is represented in cultivation by the Var. Colza or Rape, 

 with small annual root, cult, for the oil of the seed. — Var. Tt'Rxir (B. Napus) ; 

 cult, as a biennial, for the nourishment accumulated in the napiform white root. 



— Var. Rutabaga or Swedish Turnip, has a longer and yellowish root. 



B. Sinip4strum, or Sin^pis arv6nsis. Charlock. A troublesome 

 weed of cultivation in grainfields, annual, with the somewhat rough leaves barely 

 toothed or little lobcd, and nearly smooth pods spreading in a loose racepie, the 

 seed-bearing part longer than the conical (usually empty) beak.

 nual ; the leaves all pinnatifid and rough-hairy ; pods. spreading in the raceme,
