The most erotic of all plants: Coco de Mer

For centuries these unique coconuts washed ashore on the beaches of India, Maldives and Sri Lanka. The suggestive shape of the world's largest plant seed - about 40-50 cm diameter, weighing up to 20 kg - made it famous, and they were sold the world over as a symbol of fertility. They were often expensively decorated with gems, gold and silver becoming the prized possession of kings and rulers.
