Pandanus eydouxia is a species of plant in the family Pandanaceae, endemic to Mauritius.
A tall (10-12m) branching tree that forms a wide, domed canopy. The 20–25 cm wide trunk is grey and cracked, while younger stems bear brown leaf-scars. The stems are lined with many small, sharp knobs. [3]
The leaves are long, drooping and glaucous-green to yellow-green with more brownish bases. Leaf margins are lined with tiny, mild, white spines that can age to a yellow or brown. The leaf midrib also has spines, but not near the base.
This species is most easily distinguished by its very large (20–25 cm), rounded fruit-head, that is held up erect on a short peduncle that is densely covered in protective bracts. Each fruit-head holds 15-25 drupes, that are flat-topped and covered in stigmas, but otherwise variable in shape. The half or third of the drupe, that is inside the fruit-head, becomes orange or red when ripe. Each drupe holds a large number (over 50) of carpels. [4] [5] [6]
It is endemic to Mauritius, and probably the most common endemic species still occurring on that island, especially in the wetter highlands. Large clumps can still be found by rivers and in thickets. [7]
Pandanus is a genus of monocots with about 578 accepted species. They are palm-like, dioecious trees and shrubs native to the Old World tropics and subtropics. The greatest number of species are found in Madagascar and Malaysia. Common names include pandan, screw palm and screw pine. They are classified in the order Pandanales, family Pandanaceae.
Pandanus utilis, the common screwpine is, despite its name, a monocot and not a pine. It is native to Madagascar and naturalised in Mauritius and the Seychelles.
Roscheria is an endangered, monotypic genus of flowering plant in the palm family. The genus is named for Albrecht Roscher, a 19th-century German explorer, and the epithet for its single species R. melanochaetes derives from Latin and Greek meaning 'black' and 'bristle', alluding to the spines covering the trunks. They naturally occur on the Mahé and Silhouette Islands of Seychelles where they grow in mountainous rainforest and are threatened by habitat loss.
