in heraldry, the st. andrew's cross is also called tray cross. the common figures arranged crosswise are then placed in tiers (also tiered) or diagonally crossed. the cross can also appear as a herald image in the coat of arms and follows the possible representation of crosses. an older heraldic expression is the shield ten, based on the roman ten (x), which reflects the shape of the st. andrew's cross. in a narrower and smaller version, the herbalist uses the french term flan chis, as in the amsterdam coat of arms.
