I probably will not be around to see the fruits of this tree!
The Coco de Mer (Lodoicea maldivica), the sole member of the genus Lodoicea, is a palm endemic to the islands of Praslin and Curieuse in the Seychelles. It formerly also was found on St Pierre, Chauve-Souris and Ile Ronde (Round Island, an islet near Praslin) in the Seychelles group, but has become extinct on these islands. The name of the genus, Lodoicea, is derived from Lodoicus, the Latinised form of Louis, in honour of King Louis XV of France. The tree grows to 25–34 m tall. It is dioecious, with separate male and female plants. The mature fruit is 40–50 cm in diameter and weighs 15–30 kg, and contains the largest seed in the plant kingdom. The fruit, which requires 6–7 years to mature and a further two years to germinate, is sometimes also referred to as the Sea Coconut, Bum Seed, Love Nut, double coconut, coco fesse (that's "butt" in French, in case you don't know,) or Seychelles Nut. The Coco de Mer is the most interesting species of the six monospecific endemic palms in Seychelles since it is the "only true case of island gigantism among Seychelles flowering plants, a unique feature of Seychelles vegetation" (Proctor, 1984). It is one of the most universally well-known plants and holds three botanical records; the largest fruit so far recorded weighed 42 kg; the mature seeds weighing up to 17.6 kg are the world's heaviest; and the female flowers are the largest of any palm. Of the six endemic palms it is the only dioecious species, with male and female flowers located on different plants.
The Seychelles nut was once believed to be a sea-bean or drift seed, a seed evolved to be dispersed by the sea. However, it is now known that the viable nut is too dense to float, and only rotted out nuts can be found on the sea surface, thus explaining why the trees are limited in range to just two islands.
Here is some interesting reading from "Legends of the Coco de Mer."
Formerly the Coco de Mer was known as Maldive Coconut. Its scientific name, Lodoicea maldivica, originated before the 18th century when the Seychelles were uninhabited. In centuries past the coconuts that fell from the trees and ended up in the sea would be carried away eastwards by the prevailing sea currents. The nuts can only float after the germination process, when they are hollow. In this way many drifted to the Maldives where they were gathered from the beaches and valued as an important trade and medicinal item.
The unique double coconut closely resembles a woman's buttocks. This association is reflected in one of the plant's archaic botanical names, Lodoicea callipyge Comm. ex J. St.-Hil., in which callipyge is from Greek words meaning 'beautiful rump'. Other botanical names used in the past include Lodoicea sechellarum Labill. and Lodoicea sonneratii (Giseke) Baill.
Until the true source of the nut was discovered in 1768, it was believed by many to grow on a mythical tree at the bottom of the sea. European nobles in the sixteenth century would often have the shells of these nuts polished and decorated with valuable jewels as collectibles for their private galleries. The Coco de Mer tree is now a rare and protected species.
This photo shows one of the two viable nuts that came from the Seychelles, and this was recently planted here. It will take decades for this to grow to maturity... but it is believed that this will survive at this location.
