sist of a number of rays. N. lutea has a strong 
scent like brandy. 
Several species of the Mint tribe, JZentha, 
are distinctly aquatic plants, and mingle their 
pale purple spikes with other flowers by the 
water side and in ditches. 
Of the Composit, there are but few that 
grow in water; among these are the two 
species of Bur-Marigold, Szdens cernua and 
tripartita, tall plants with brownish yellow 
flowers, the heads drooping, the leaves of 
cernua undivided, those of ¢vzpartzta 3-partite ; 
they are found in shallow pools. The common 
Flea-bane, Pulicaria dysenterica, is abundant in 
ditches, displaying large yellow-rayed flowers, 
and having thick woolly foliage. Several 
species of Groundsel, Sezeczo, may also be 
named, as S. aguaticus and paludosus—the latter 
rare—in the fens in eastern counties. Of two 
species of Czzerarza, Flea-wort, the marsh kind, 
C. palustris, should be found, with yellow 
flowers and woolly stems. Mr. Babington 
includes this genus under Sezeczo, but it is dis- 
tinguished by its involucres having scales at 
their base, which the plants usually comprised 
under Sezeczo have not.
