Male flowers on the spike and females in axils below.

David Fenwick found the site, identified the plants and took me there to see them.

A comment from Lydney in Gloucestershire:
"This plant has been common in this area this year (2008), probably introduced with imported grain. It has been found under wild bird tables and in a neighbours chicken run."
