The ditches about Oxford always yield an abundance of this handsome 
and conspicuous plant. The earlier leaves are submerged, and are often 
most beautifully dissected (Merrett’s record refers to this); these sub- 
merged leaves have been gathered in January, in excellent condition. 
A form occurred by Port Meadow, in which the bracteoles were so much 
developed as to become foliaceous, the stem leaves had very narrow 
leaflets with the margin dentately cut. The whole appearance of the 
plant was very different from the type with which it grew. The fruit was 
quite normal.
