N o t unfrequent in a muddy foil on the Norfolk coaft, from
whence Mr. D. Turner communicated thefe fpecimens. It is
found alfo in Effex, Kent, and the fouth of England, flowering
about May. The root is annual. This differs from the
C. officinalis at firft fight in being fmaller. Its ftem-leaves are
narrower, lanceolate rather than ovate, toothed rather than
finuated, and often nearly entire or but flightly waved. The
radical ones are very unlike thofe of the officinalis, being much
fmaller in proportion to the others, lanceolate or ovate, and for
the mod part perfectly entire. In the flowers of thefe two
plants little difference is to be found ; and indeed their herbage
is fo variable, that all we have hitherto mentioned would hardly
difcriminate them; and Mr. Hudfon’s conjecture of their being
mere varieties might be affented to, did not the fruit afford
certain and clear marks of diftinCtion. The pouches of the
C. anglica are larger than thofe of the laft fpecies, elliptical,
crowned with a ftyle one third of their own length; they are
all over ftrongly marked with a net-work of prominent veins,
fcarcely at all to be perceived in thofe of the more common
kind.
C. danica differs from both thefe in its triangular leaves,
which all ftand on footftalks. Its fruit agrees with C. anglica.
