nalis the flowers seem to be constantly monoecious, and
both stamen and pistil destitute of floral covering. Fruit
on a short peduncle, larger than in C. verna, orbicular, compressed,
of 4 lobes, or seeds as they are called, which are
also compressed and have a sort of transparent margin.
The specimens here figured were communicated by
Mr. Borrer, from a ditch at Amberley, Sussex, between
the Castle and the Wild Brook, where they grew at the
bottom of deep water, even while flowering, in June 1826.
Plants raised from their seeds were cultivated by Mr. Sow-
erby for two years, and found to preserve all the characters
of the parent; never producing floating leaves either in
spring or summer, and never rising to the surface of the
water. The species has been found also near London by
Petiver, and in Clunie Loch, Scotland, by Mr. Arthur
Bruce. Mr. Wilson finds it in a beautiful state in the
outlet of Llyn Maclog, Anglesea. The same gentleman
has sent me C. verna without the broad floating leaves;
but the linear leaves have the loose reticulation of that species,
and are narrower than in C. autumnalis.—W. J. H.
The delicate transparency of the stem in the Sussex
specimens, and in the produce of their seeds, has particularly
struck us when comparing them with the varieties of
C. verna at all seasons.
