A nesselblatt is a highly stylized nettle leaf; it is found in German heraldry, c.1370, in the arms of the Counts von Holstein [Gelre 97v]. Though some books claim it is equivalent to a bordure indented, the nesselblatt is actually an independent charge: it does not follow the line of the shield, but always keeps its basic triangular shape. See also leaf, seeblatt.
