788 TETRADYNAMIA. SILIQUOSA. Raphanus, 
Root tapering. Stems branching, leafy, cylindrical, covered with reflexed 
hairs; sometimes very short. Leaves alternate, on leaf-stalks, broad- 
spear-shaped, unequally waved and serrated, smooth, and of a lightish 
green, not glaucous. Fruit-stalks terminal, very long, forming a bunch¬ 
like corymbus, greatly elongated with flowering. Blossoms yellow, only 
half the size of those of S. tenuifolia. Calyx a little hairy. Pod slender. 
Fruit-stallcs , and pedicles often rather hairy. Seeds two-ranked, but still 
less accurately so than in the preceding. Calyx in both spreads less than 
the characters of Sinapis requires. Sm. E.)

Stem one to two feet high, rough with transparent reflexed hairs. Leaves 
sometimes rough with hairs; the lower lyre-shaped, wings alternate, 
heart-oblong, serrated, the lowermost very small, the odd one large, 
rounded at the end, scolloped; the upper oblong-spear-shaped, scollop- 
serrated. Leaf-stalks generally rough. Calyx beset with white hairs, 
except the base which is smooth. Blossom generally yellow, but occa¬ 
sionally white, or violet, with dark veins. Pod , joints falling off sepa¬ 
rately. Linn. Plant generally of a sea-green cast. Petals of whatever 
colour, veined with dark lines. Woodw. ( Seeds large, solitary in each 
joint. Pod , with its beak, an inch and a half long. E.) 
(Var. 2. Radical leaves interruptedly lyrate; all the leaves rough, and 
rather sharply toothed. Blossom more yellow, and less veiny than in 
the preceding. Root large and succulent, conjectured to be biennial, or 
sometimes triennial. Always grows near the sea. E. Bot. (The chief 
difference seems to consist in its larger size, its leaves being less simply 
lyrate, and more serrated, and the pods perhaps more strongly furrowed ; 
* (This weed, which has now over-run the whole arable land of the Isle of Thanet, was 
first remarked some twenty years ago near to the beach at Broad-stairs, and is believed to 
have been introduced on that spot by a corn-laden vessel wrecked on that part of the coast. 
-—It will be observed that the other stations of this plant might induce a similar suspicion 
as to its origin in Britain. E.)

generally cultivated. E.)
