What emblem appears on the flag and shield of Gondor in Tolkien’s legendarium?

The White Tree of Gondor is the emblem shown on Gondor’s flag and shield in Tolkien’s legendarium.

The symbol represents the White Tree of Minas Tirith, which stands in the Court of the Fountain. It is linked to the earlier White Trees of Númenor and ultimately to the Two Trees of Valinor, making it a sign of descent, memory, and rightful kingship.

When the line of Gondorian kings ends, the tree dies. During the events of The Lord of the Rings, Aragorn finds a living sapling on Mount Mindolluin and brings it to the city after becoming king.

The emblem is often shown together with the Seven Stars and a crown. The White Tree should not be confused with the White Tree of Valinor, which belongs to the mythology’s earlier sacred history.
