26 THE CRUCIFER FAMILY. - [Matthiola, 
petals obovate. Pod 4 or 5 inches long, crowned by the short stigmas, 
which are rather thickened at the base. 
On cliffs and stony places on the sea-coast round the Mediterranean, 
and up western Europe, at least to Bayonne. In Britain fully estab- 
lished on cliffs in the Isle of Wight, and perhaps some other parts of 
the south coast, but probably an escape from cultivation. Fl. swmmer. — 
2. M. sinuata, Br. (fig. 49). Sea Stock.—Like the last, but more 
herbaceous and diffuse, and covered all over with a short hoary down, 
which is, however, much softer and more dense. Branches very 
spreading. Lower leaves deeply sinuate. Flowers nearly as in M, 
incana, but the pods more compressed, usually more or less covered 
with glandular protuberances, and the stigmas very short, scarcely 
thickened at the base. 
On sandy seashores, common all round the Mediterranean, and up the ~ 
west coast of Europe to Ireland, and some points of the south and west 
coasts of England and Wales. Fl. summer. [Very fragrant at night.] 
Il. CHEIRANTHUS. WALLFLOWER. 
Habit and character of Matthiola, except that the hairs are bipartite 
and appressed, the flowers are orange or yellow, or under cultivation, 
red, purple, or brown, the pod more distinctly flattened, the very short 
stigmas spreading horizontally, not erect, and usually borne on a 
distinct style, and the seeds not winged, 
The genus is reduced by some to a single species, by others made to 
include a very few species from southern Kurope and the Canary 
Islands. 
1. ©. Cheiri, Linn. (fig. 50). Wallfower.—A perennial of longer 
duration and more woody than the common Stock, more branched and 
less hoary, the hairs forked at the base, and closely pressed on the 
surface, or often quite green and nearly glabrous. Leaves narrow, 
pointed, quite entire. Flowers rather large, generally of a rich orange- 
yellow, and sweet-scented, but varying from pale yellow to a deep red. 
Pods 2 to 8 inches long, the valves with a slightly prominent midrib. 
A native of rocky situations, in southern Hurope, but spreads rapidly 
from cultivation, and is now abundant, apparently wild, on walls, old 
buildings, and rocky places near habitations, in many parts of central 
and even northern Europe. In Britain very frequent under the latter 
circumstances. J. spring. | 
lll. BARBAREA. WINTERCRESS. 
Herbs, only differing from the yellow-flavoured Nasturtia by their 
longer pod, the midrib more conspicuous, and the seeds apparently 
arranged in a single row, and from £rysimum and Sisymbrium by 
accumbent, not incumbent radicle. 
A very small genus, spread over the temperate regions of the globe. 
1. B. vulgaris, Br. (fig. 51). Wéintercress, Yellow Rocket.—A perennial 
of short duration, stiff and erect, green and glabrous, sparingly branched, 
1 to 2 feet high. Leaves mostly pinnate, with the terminal lobe large, 
broad, and very obtuse, while the lower ones are few, small, and narrow ;
