List of largest seeds

Add article description

The largest seed in the world is the coco de mer,^[1]^[2] the seed of a palm tree.^[3] It can reach about 30 centimetres (12 inches) long, and weigh up to 18 kilograms (40 pounds). The coco de mer, which produces a giant, dark brown seed,^[4] has been protected by the government of the Seychelles because of its rarity^[5] – the tree can grow up to 31 m (102 ft) tall, with leaves measuring 6 m (20 ft) long and 3.6 m (12 ft) wide. Kigelia or "sausage seed" (botanical name Kigelia africana) can produce pods weighing up to 12 kg (26 lb), and 12–20 cm (4+1⁄2–8 in) long, but the pod contains seeds.

Lodoicea maldivica, native to the Seychelles Archipelago, found in the Indian ocean
