Moft people are acquainted with the leaves of the Water-crefs, few comparatively with the plant in flower ; 
. to render their knowledge of it complete, we have reprefented it in both flates. 
It is a plant common not only to Europe but America, grows fpontaneoufly in rivulets and watery ditches, 
and flowers in June, July, and Auguft. 
It varies in its appearance from feveral caufes; the leaves, if growing in the fhade, are of a green colour, 
if expofed to the fun, purplifh brown; they rarely vary in their fhape, yet we have feen inftances of their 
being confiderably elongated by growing in a ftream where the current has been rapid; the alteration produced 
on the leaves of many other plants from the fame caufe, is well known to Botaniíls: in this flate there is a 
poffibility that the leaves, by miftake, may be eaten for thofe of the creeping Water-parfnep (Sium nodiflorum) 
which ufually grows with it; if by accident they fhould, no great danger is to be apprehended, as there are 
no inflances on record of that plant's being poifonous ; to avoid, however, any alarm from fuch a circumftance, 
thofe who are in the pra&tice of eating Water-creffes, fhould obferve, that the leaves are nearly round, and 
that they have the crefs-like tafte, the leaves of the Water-parfnep are not only long and pointed, but fawed 
on the edges, they are alfo of a much paler colour, and have a very different tafle. 
Ray mentions two other fpecies of Water-crefs, which can only be confidered as mere local varieties.
