BRITISH WILD FLOWERS. 
GENUS I. 
THE STOCK. (Matthiola, R. Broion.) 
Lin. Syst. TETRADYNAMIA SILIQUOSA. 
Generic Character. —Siliqua taper. Stigmata connivent, thick- | Seeds compressed, in one row, generally bordered. Cotyledons flat, 
ened, or connate at the back. Calyx with two sacs at the base. I (Dec.) 
Description, &c. —Two species of Stock are occasionally found wild in Great Britain, but only one of them 
appears to be a true native. The other (the common Queen’s Stock) has only been found wild on the cliffs near 
Hastings, in Sussex, where its seeds had most probably been conveyed by some accidental circumstance. When 
this genus was separated from Cheiranthus, the name of Matthiola was given to it, in honour of an Italian 
physician named Matthioli. The difference between the two genera lies in the stigma, which in Matthiola is 
sessile, and Cheiranthus is supported by a style. 
1. — THE GREAT SEA-STOCIv. (Matthiola sinuata, R. Brown.) 
Synonymes. —Cheiranthus sinuatus, Lin. ; C. tricuspidatus, Huds. 
Engravings. —Eng. Bot., t. 462; 2d ed., t. 948 ; and our fig. 5, 
in PI. 9. 
Specific Character. —Stem herbaceous, spreading. Leaves downy, 
glandular, obtuse, sinuated; those of the branches undivided. Pods 
rough, with prominent glands. ( Smith.) 
Description, &c. —This plant, though it is said not to be truly indigenous, has been so long naturalised on 
the sandy sea-shores of Wales and Cornwall, as to have all the appearance of a British plant. It is large and 
robust, growing to the height of two feet or more, and spreading in proportion. The leaves are covered with a 
white starry pubescence, and are rather succulent; the lower ones are sinuated on each side, which is the origin 
of the specific name. The plant is a biennial, and it flowers from May to August. 
THE SHRUBBY, OR QUEEN’S STOCK. (M. incana, Smith.) 
This species is the common Stock-Gillyflower, or July flower, of our gardens. Its flowers are purple, and 
it is extremely fragrant, remaining in flower nearly all the summer. 
“ The white and purple Gillyflowers that stay 
In blossom—lingering summer half away.”— Clare. 
It has never been found growing wild in England in any place but the cliffs near Hastings, but there it takes 
a decidedly shrubby character. It is very common in gardens, and no flower is more improved by cultivation. 
GENUS II. 
THE WALL-FLOWER. (Cheiranthus, Lin.) 
Lin. Syst. TETRADYNAMIA SILIQUOSA. 
Generic Character.— Siliqua taper, or compressed. Stigma two-lobed, or capitate. Calyx with two sacs at the base. Seeds in one row, 
ovate, compressed. (Dec.) 
Description, &c, —Only one species of this genus is wild in Britain. The Stocks were formerly included 
in it; but they have been separated on account of the difference in the formation of the stigma. The name of 
Cheiranthus is said to be derived from an Arabic word applied to a kind of stock, and signifying fragrant. 
Wall-flower alludes to the general habits of the plant, which grows more luxuriantly on old walls than in any 
other situation.
