Leaves sub-cordate, 3-lobed, with the lobes again lobed, and 

 crenate or dentate. Pruiting pericline with hooked spines, except 

 at the apex, which is unarmed, and terminates in two straight 

 beaks. 



Rare, and not even naturalized, but occurring from time to 

 time in waste places and about dunghills, principally within the 

 metropolitan district. It has occurred in the counties of Dorset, 

 Hants, Kent, Surrey, Middlesex, and Northumberland. I have 

 found it on the mud dredged from the Thames, and laid on 

 Battersea Fields during the formation of Battersea Park.
