vi. crucifers : brassicete. [ Brassica . 
Seeds in a single row. Calyx erect. — Name derived from 
the Celtic bresic (modern Gaelic praiseach ), a kind of cabbage, 
or rather pottage, made of it. 
* Valves of pod \-nerved, veiny ; beak usually sterile. 
1. B. olerdcea L. ( Sea C.) ; root caulescent cylindrical 
fleshy, all the leaves glabrous glaucous waved and lobed, upper 
ones oblong sessile. E. B. t. 637. 
Cliffs by the sea : Devonshire, Dover, Wales, Cornwall, York- 
shire, and in the Frith of Forth. $. 5 — S. — Varying in height, 
1 — 2 feet. Leaves thick, subcarnose. the uppermost undivided, 
hut toothed. Flowers large, yellow. — The origin of our garden 
Cabbage. 
2. B. * Ndpus L. {Rape, or Cole-seed ) ; leaves glabrous 
somewhat glaucous especially on the under side, lower ones 
lyrate toothed, upper cordato-lanceolate amplexicaul, pods 
spreading. E. B. t. 2146. 
Corn-fields and waste ground, frequent in England. $ . 5, 6. — 
1 — 2 feet high. Root slender or fusiform. Lobes of the lower 
leaves crenate, upper leaves entire more glaucous. Petals yellow, 
rather small. Pods torulose. — The slender-rooted variety is culti- 
vated for the oil produced by its seeds, which after pressure are 
formed into cakes, and used as manure and for feeding cattle ; hut the 
slender-rooted variety of B. campestris is much more employed for 
the same purpose on the Continent, under the name of Colsa. 
3. B. campestris L. {common wild N.) ; upper stem-leaves 
cordate acuminate amplexicaul glabrous, lower and radical 
ones lyrate dentate subhispid glaucous, pods erect. E. B. 
t. 2234. 
Corn-fields and sides of rivers and ditches, in many places. 
0 or $. 6, 7. — Root fusiform, slender and annual in the wild 
plant, often turnip-shaped and biennial in the cultivated one. 
Stem hispid below. Flowers yellow. Pod cylindrical or obscurely 
4-angular ; seeds forming slight prominences ; beak awl-shaped, 
striate, sometimes with a single seed . — Apparently the origin of 
the Swedish Turnip of our agriculturists, and in Scotland it has 
never been found except where the Swedish Turnip had been pre- 
viously cultivated. 
4. B. * Rapa L. {common T.) ; root orbicular or oblong 
fleshy, radical leaves lyrate scabrous not glaucous, lower 
stem-leaves incised, upper ones cordato-ovate acuminate am- 
plexicaul smooth. E. B. t. 2176. 
Borders of fields and waste places. A . 4 — 7. — Varying ex- 
ceedingly in height, according to soil. Upper leaves subglaucous; 
all more or less toothed. Although this and the last two are readily 
distinguished in cultivation by their radical leaves alone, there are
