Document 6: Saint Barthélemy: As the terrain is generally arid, the hills have mostly poor soil and support only cacti and succulent plants. During the rainy season the area turns green with vegetation and grass. The eastern part of the island is greener as it receives more rainfall. A 1994 survey has revealed several hundred indigenous species of plants including the naturalized varieties of flora; some growing in irrigated areas while the dry areas are dominated by the cacti variety. Sea grapes and palm trees are a common sight with mangroves and shrubs surviving in the saline coastal swamps. Coconut palm was brought to the island from the Pacific islands. Important plants noted on the island are:

Document 10: Legends of the coco de mer: Nut and tree of the coco de mer, a rare species of palm tree native to the Seychelles archipelago in the Indian Ocean, is the subject of various legends and lore.

Before the Seychelles were discovered and settled, nuts of this species were sometimes carried by the ocean currents to distant shores, such as those of the Maldives, where the tree was unknown. These floating nuts did not germinate. The exceptional size and suggestive form of the nut, the circumstances of its discovery, and some unusual qualities of the trees have given rise to several legends.
