 Ludwigia palustris is also known as Hampshire Purslane, meaning 
Hampshire in Southern U.K.  In Hampshire, the only UK county with any 
significant number of plants, it grows in wet areas and is a rather 
insignificant sprawling plant. Its flowers comprises four sepals and 
no petals.  It is a member of the Willowherb Family, Onagraceae, and 
is so close to the Evening Primroses.

Is it a native in USA or another introduction from Europe? 

Another UK water plant is Branched Bur-reed, Sparganium erectum - 
could this be your Branch Burrweed?  

It seems rather strange that a landowner is told that they have 
endangered species on their land but not told how to identify them.  
You could very easily destroy the plants without even knowing that 
they are there.
