When growing in water of some depth the leaves below the surface are 
strap-shaped, winged, nearly like those of Hottonia ; those above spear- 
shaped, serrated. Linn. Stem upright, (two or three feet high, E.) 
branched. Leaves spear-shaped, variously toothed, smooth, half em¬ 
bracing the stem. Fruit-stalks much longer than the pods, and much 
longer than in N. terrestre. Pod oblong, very short, smooth, at first 
expanding, afterwards hanging down. Woodw. Stem smooth, scored, 
crooked at the joints. Leaves egg-spear-shaped, scolloped and set with 
little teeth at the edge, with often from one to three winged clefts at the 
base. Leafstalks semi-cylindrical, channelled above. Fruit-stalks while 
in flower about half an inch long, and upright, but afterwards bending 
back and pointing downwards. Flowers yellow, numerous, in clusters. 
* Universally used as an early and wholesome spring salad : (and may be easily increased 
by transplanting into mud, and not cutting till the second year. E.) It is an excellent 
antiscorbutic and stomachic, with less acrimony than Scurvy-grass. It is an ingredient iin 
the anti-scorbutic juices. (The expressed juice, which contains the peculiar taste and 
pungency of the herb, may be taken in doses of an ounce or two, for the purposes 
recommended by Hoffman.—Of late Water Cress has has been cultivated on many acres of 
land in the vicinity of London, whence the markets are supplied daily throughout the year* 
The environs of Paris also provide the same article from gardens appropriated to its culture.. 
Jn France it is not only used as salad, but dressed like spinach, and the picked leaves sen edl 
with roasted fowl compose the favourite Poulet mi wessons* E-)
