The centrepiece of the arms, the shield, bears a palm tree and St. Edward's Crown on a base of three white wavy lines representing the ocean, a sun in splendour in the upper-left corner, and the Union Flag in a chief at the top.

The crest comprises a naval crown through which rises a red tower, with a crosslet loophole shaped like the Holy Cross, bearing the territory's flag; there is no helm or mantling.

This latinised name refers to the non-existent continent of Lemuria, once thought to occupy the Indian Ocean.

The palm tree and royal crown also feature in the flag of the British Indian Ocean Territory.
