List of endemic plants of Seychelles

Last updated

The Granitic Seychelles are a group of islands which form the main part of the island country Seychelles. These islands sit on the Seychelles Bank and composed mostly of granite derived from ancient continental crust. The Granitic Seychelles are home to several dozen endemic species and subspecies of plants, including the endemic genera Deckenia , Glionnetia , Lodoicea , Medusagyne , Nephrosperma , Northia , Paragenipa , Phoenicophorium , and Protarum , Roscheria , Vateriopsis , Verschaffeltia , and Xyroschoenus .

Aldabra and Seychelles' other coralline islands – the Amirante Islands, Farquhar Group, and Southern Coral Group (Coëtivy and Île Platte) – which are known as the Outer Islands or Coralline Seychelles, are politically part of Seychelles, but the World Geographical Scheme for Recording Plant Distributions treats them a separate botanical country.

Seychelles, officially the Republic of Seychelles, is an island country and archipelagic state consisting of 115 islands in the Indian Ocean. Its capital and largest city, Victoria, is 1,500 kilometres east of mainland Africa. Nearby island countries and territories include the Comoros, Madagascar, Mauritius, and the French overseas departments of Mayotte and Réunion to the south; and the Chagos Archipelago and Maldives to the east. Seychelles is the smallest country in Africa as well as the least populated sovereign African country, with an estimated population of 100,600 in 2022.

<i>Lodoicea</i> Genus of plant, Coco de Mer

Lodoicea, commonly known as the sea coconut, coco de mer, or double coconut, is a monotypic genus in the palm family. The sole species, Lodoicea maldivica, is endemic to the islands of Praslin and Curieuse in the Seychelles. It has the largest seed in the plant kingdom. It was also formerly found on the small islets of St Pierre, Chauve-Souris, and Ile Ronde, all located near Praslin, but had become extinct there for a time until recently reintroduced.

<i>Gastonia</i> (plant) Genus of flowering plants

GastoniaCommerson ex Lamarck is a formerly accepted genus of plants in the ivy and ginseng family, Araliaceae. It had been known as an unnatural group, but was recognized as late as 2010, when its nine species were distributed to four different subgenera of the large genus Polyscias. Because the genus Gastonia is now obsolete, its species are herein referred to by their names in Polyscias.

<i>Roscheria</i> Species of plant

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.

Glionnetia is a monotypic genus of flowering plants in the family Rubiaceae. The genus contains only one species, viz. Glionnetia sericea, which is endemic to Mahé and Silhouette Island in the Seychelles. The species thrives mainly on high ridges in the mountains and it does not seem to grow well at lower altitudes. Glionnetia sericea is a small flower with paniculate terminal inflorescences and it has capsules that are dispersed by wind.
