Hyprocoryir votearts. (Plate VIII. Fig. 29.) White-rot 
or Marsh Pennywort. Bogs, marshy places, and banks of 
ponds produce this curious, round-leaved plant. It will 
be at once known by the peculiar shaped leaf, which re- 
sembles that of the Nasturtium ; it is also confined to watery 
places. ‘The stems creep very much beneath the ground or 
moss on which it grows, and are rather difficult to raise, as 
they take root at short intervals, and thence produce the 
flowers and leaves. The former are seldom seen without 
being dug up, and are rather insignificant in appearance.
