Brdssica.~\ vi. cruciferte: brassicea:. 
(We adopt Senebiera in place of Coronopus, in consequence 
of its being generally preferred ; but the latter appellation given 
by Gsertner is certainly the oldest ; and although it may not 
happen to be the precise plant of the ancients, many other 
received names are in the same predicament.)

undivided crested with little sharp points, style prominent. 
Coronopus Ruellii Sm. : E. B. t. 1660. S. pinnatifida DC. 
Waste ground, not unfrequent in England. Rare in Scotland. 0.

segments linear. Flowers very small, white, in lateral axillary corymbs. 
Pouch large in proportion to the flower, curiously crested. Coti/ledons 
(in the whole genus) nearly as in Subularia.

wrinkled lobes, style very short. Coronopus Sm. FI. Brit. 
Lepidium E. B. t. 248.

yellow. Cultivated for the sake of the blue dye which it yields,

where it was formerly extensively cultivated.
