The Queen's Personal Flag for Barbados consisted of a yellow field with a bearded fig tree, a long-established symbol of the island of Barbados, and the national flower the Pride of Barbados flowers in each of the upper corners. A blue disc of the letter "E" crowned surrounded by a garland of gold roses is displayed prominently on the flag within the centre of the tree. The disc is taken from the Queen's Personal Flag.[5][6]
