1. L. campestre, Br. (fig. 103). Mithridate Pepperwort.—An annual 
or biennial, nearly a foot high, more or less hoary with minute scaly 
hairs, or rarely quite glabrous; the stem solitary, erect or nearly - 
so, usually branched in the upper part. Radical leaves stalked, ob- 
long, entire or pinnatifid, with a large terminal Jobe; the upper ones 
oblong or lanceolate, entire or slightly toothed, clasping the stem 
with short, pointed auricles. Flowers very small. Anthers yellow. 
Pods numerous, on spreading pedicels, broadly ovate, thick when 
ripe, nearly surrounded by the wing, which is narrow at the base, but 
broad and slightly notched at the top, with a short, often very minute 
style. 
In hilly pastures, cultivated and waste places, over the greater part 
of Europe, from Sweden to the Caucasus. Generally distributed over 
England, Ireland, and southern Scotland. l. summer. 
2. L. Smithii, Hook. (fig. 104). Smzth’s C.—Very near L. campestre, 
but forms a more or less perennial stock. The stems are several 
together, much shorter, and decumbent at the base; the foliaze more 
hairy, the flowers rather larger, the anthers violet, and the pod glabrous. 
In hilly pastures, cultivated and waste places in western Europe, 
from Spain and Portugal, up western France, to England, Ireland, and 
southern Scotland. Fl. spring and autumn. It should perhaps be 
united as a mere variety with the L. hwrtum from south-western Europe, 
which is hairy all over, including the pods, and the L. heterophyllum 
from western Europe, which is glabrous all over. 
3. L. Draba, Linn. (fig. 105). Hoary C.—A perennial about a foot. 
high, more or less hoary with a minute down. Stems stout and erect, 
branching above. Leaves oblong or broadly lanceolate, usually slightly 
toothed, 14 to 2 inches long, the lower one stalked, the upper ones 
clasping the stem with projecting auricles. Racemes not much 
lengthened, forming a broad flat corymb. Pods about 2 lines broad 
and not quite so long, very thick, the valves sharply keeled, but not 
winged, the style prominent. 
In waste places, by roadsides, &c. ; common in central and southern 
Europe, and temperate Russian Asia. Rare in Britain, and only as an 
introduced plant in afew English counties, Fl. spring or early summer. 
4. L. latifolium, Linn. (fig. 106). Duittander.—A stout, erect 
perennial, attaining 2 feet or more in height, of a pale green, but 
glabrous. Stems much branched above, but forming a large loose 
panicle, not a flat corymb as in LZ. Draba. Radical leaves large, ovate, 
toothed, on long stalks ; stem-leaves oblong or broadly lanceolate, 2 or 
3 inches long, the lower ones stalked and mostly toothed, the upper
