First record: Merrett, 1666. The few fruiting specimens we have seen 



are C. demersum, and this is probably the usual Middlesex plant. 



G. submersum is stated to have been found (VII.) in a piece of water 



at the top of Eel-brook Meadow, Parson's Green ; Irv. H. B. P. 373. 



We have seen dried plants collected there by Dr. Morris in 1845, 



but without fruit. Mr. Watson says of C. submersum, 'Mr. Thos. 



Moore finds it in Middlesex,' Cyb. Br. iii. 430; and it is included 



in the Essex, but wanting in the Surrey and Herts Floras.

t This name is erroneously referred by Ray, R. Cat. i. 17, who could not have seen 

 Johnson's figure, to his Alsine palustris Portulacce aquaticce similis {=Montia fontana, L.).
