(Map updated: March 2008)
 

A rather local plant, somewhat unpredictable in its occurrence, of sandy or shingly upper sea shores. The plant has small silvery-grey leaves on stems which sprawl across the ground.

Little brown pointed fruits of a characteristic shape are freely produced after the tiny pink flowers.

All names: Polygonum oxyspermum Meyer & Bunge ex Ledeb.; Polygonum raii Bab.; Polygonum roberti auct.
