Surely it is a libel to tall this ])lant Xasturtnon, which 

 signifies ''twisted nose," and is given to Water-cress simply 

 because we are supposed to turn uj) our noses when we eat 

 its acrid leaves. Those who go out to gather flowers will 

 seldom pause to pick this insignificant ))lant, whose clusters 

 of small white flowers grow close beside, or actually in, the 

 streams and ponds, and whose only claim \\\){)x\ our attention 

 lies in the pleasant pungent flavour of its leaves.
