in Oxfordshire. It abounds in the streams of Hertfordshire
and Essex. Mr. Borrer has found it in Kent, Mr. Babing-
ton in Hampshire, Cambridgeshire and Oxfordshire, and Mr.
Bloxam in Leicestershire. It is probable that many of the
recorded stations of OE. Phellandrium belong to this species,
which, as far as our observation goes, is much the more
common plant in the middle and south-east of England.
(Enanthefluviatilis is never healthy except when growing in
running water. Its aquatic leaves (as noticed by Dillenius)
are often to be found in abundance in situations where it seldom
or never flowers, and the great difference existing between
them and those of OE. Phellandrium first drew attention to the
plant. Those of OE. Phellandrium have their segments quite
capillary, resembling Fennel; while those of our plant have
