panded into a narrow wing at the top. Seeds one in each cell, the radicle 
usually incumbent on the back of the cotyledons. | 
A numerous and rather natural genus, widely diffused over the whole 
range of the Order. It is readily distinguished from Zberis by the small 
petals all equal, and from all other British siliculose Crucifers, with 
laterally compressed pods, except Senebiera, by the single seeds in each 
cell. 
Pods winged at the top.

—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, oblong, entire 
or pinnatifid, with a large terminal lobe; the upper ones oblong or lanceo- 
late, 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 
Kurope, from Sweden to the Caucasus. Generally distributed over England, 
Ireland, and southern Scotland. 7. summer. 
2. G. Smithii, Hook. (fig. 103). Smith’s Cress.—Very near L. cam- 
pestre, but forms a more or less perennial stock. The stems are several 
together, much shorter, and decumbent at the base; the foliage more 
hairy, the flowers not quite so small, the anthers violet and the pod 
glabrous. a 
In hilly pastures, cultivated and waste places in western Europe, from 
Spain and Portugal, up western France, to England, Ireland, and southern 
Scotland. 17. spring and autumn. It should, perhaps, be united as a mere 
variety with the LZ. hirtum from south-western Europe, which is hairy all 
over, including the pods, and the LZ. heterophyllum from western Europe, 
which is glabrous all over. 
3. G. Draba, Linn. (fig. 104). Hoary Cress.—A perennial about a foot 
high, more or less hoary with a minute down. Stems stout and erect, 
branching in the upper part. Leaves oblong or broadly lanceolate, usually 
slightly toothed, 13 to 2 inches long, the lower ones 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.
