Which fruit has the largest seeds on a tree-bearing fruit?

The coco de mer, a palm native to the Seychelles, is famous for producing the largest and heaviest seeds of any plant. Individual seeds can weigh around 15 to 30 kilograms, making them far larger than the seeds of most fruits. The plant grows naturally only on a few islands and has become a symbol of Seychelles biodiversity. Its unusual fruit has long fascinated botanists and travellers alike. Because of its size and rarity, it is one of the most remarkable botanical records in the world.
