List of world's largest seeds

Lodoicea maldivica, native to the Seychelles Archipelago, found in the Indian Ocean.

The largest seed in the world is the coco de mer,[1][2] the seed of a palm tree.[3] It can reach about 12 inches (30 cm) long, and weigh up to 40 pounds (18 kg). The coco de mer, a giant, dark brown seed,[4] has been protected by the government of the Seychelles because of its rarity.[5] The coco de mer tree can grow up to 100 feet (31 m) tall, with leaves measuring 20 ft (6 m) long and 12 feet (3.6 m) wide.
