Indigofera is a large genus of over 750 species of flowering plants belonging to the pea family Fabaceae. They are widely distributed throughout the tropical and subtropical regions of the world.
The Socotra sparrow is a passerine bird endemic to the islands of Socotra, Samhah, and Darsah in the Indian Ocean, off the Horn of Africa. The taxonomy of this species and its relatives is complex, with some authorities, including BirdLife International, recognising this species and the very similar Abd al-Kuri sparrow, as well as several from mainland Africa, as separate, and others lumping all these species and the probably unrelated Iago sparrow.
The Socotra cormorant is a threatened species of cormorant that is endemic to the Persian Gulf and the south-east coast of the Arabian Peninsula. It is also sometimes known as the Socotran cormorant or, more rarely, as the Socotra shag. Individuals occasionally migrate as far west as the Red Sea coast. Despite its name, it was only confirmed in 2005 that it breeds on the Socotra islands in the Indian Ocean.
Indigofera marmorata is a species of legume in the family Fabaceae. It is endemic to north-central Socotra in Yemen. Its natural habitats are subtropical or tropical dry forests and subtropical or tropical dry shrubland.
Indigofera sokotrana is a species of plant in the family Fabaceae. It is endemic to the Hajhir Mountains of Socotra in Yemen. The natural habitat of Indigofera sokotrana is subtropical or tropical dry forests.
Lotus mollis is a species of legume in the family Fabaceae. It is native to the islands of Socotra and Samhah in the Socotra Archipelago of Yemen. Its natural habitat is rocky areas.
Indigofera cloiselii, synonym Vaughania cloiselii, is a species of legume in the family Fabaceae. It is endemic to Madagascar.
Hypericum balfourii is a species of flowering plant in the family Hypericaceae. It is endemic to Socotra, an island archipelago that is part of Yemen. It grows in mountain shrubland dominated by Cephalocroton. It is usually found on granite terrain above 600 meters in elevation.
Hypericum fieriense is a species of flowering plant in the St. John's wort family Hypericaceae. It is endemic to Socotra, an island archipelago that is part of Yemen. It grows in mountain shrubland dominated by Cephalocroton, where it can be found with the endemic tree Dracaena cinnabari. It is rarer than other local shrubby Hypericum species. It can be distinguished from them by its pubescent herbage.
Hypericum scopulorum is a species of flowering plant in the family Hypericaceae. It is endemic to Socotra, an island archipelago that is part of Yemen. It is a common plant in shrubland habitat, and it is a dominant species in some areas along with Cephalocroton and another local endemic, Libinhania rosulata.
Hypericum tortuosum is a species of flowering plant in the genus Hypericum. It is found only in Socotra, Yemen, where it is endemic. The species is an apomorphic relative of the other Socotran species in Hypericum sect. Triadenioides and is most closely related to Hypericum scopulorum. Its natural habitats are subtropical or tropical dry forests and subtropical or tropical dry shrubland.
The Socotra starling is a species of starling in the family Sturnidae. It is endemic to Socotra island, which is off the southeast coast of Yemen.
Euphorbia arbuscula is a species of plant in the spurge family (Euphorbiaceae). It is endemic to the archipelago of Socotra in Yemen. Its natural habitats are subtropical or tropical dry forests and subtropical or tropical dry shrubland.
Kraussia socotrana is a species of plant in the family Rubiaceae. It is endemic to Socotra, Yemen. Its natural habitats are subtropical or tropical dry shrubland and rocky areas. The type was collected from Wadi Irih on the Nogad Plain.
Lycium sokotranum is a species of flowering plant in the nightshade family, Solanaceae, that is endemic to the Socotra archipelago in the Indian Ocean (Yemen). It is a spiny, much-branched shrub that is <2 m tall. It is widespread and often abundant on coastal plains and limestone plateaus of Socotra and on the central plains of Abd al Kuri.
Socotrella is a monotypic genus of plant in family Apocynaceae. It contains the single species Socotrella dolichocnema, which is endemic to Socotra.
The Socotra buzzard is a medium to large bird of prey that is sometimes considered a subspecies of the widespread common buzzard. As its name implies, it is native to the island of Socotra, Yemen. Although it is listed as vulnerable in the IUCN Red List, its population is considered to be stable.
The Socotra golden-winged grosbeak or Socotra grosbeak is a finch endemic to Socotra, an island in the Indian Ocean off the coast of Yemen. R. socotranus is by some authorities held to be the only species of the then-monotypic genus Rhynchostruthus, including all other golden-winged grosbeaks therein as subspecies. But in recent times the three populations are usually considered a distinct species, with R. socotranus being limited to the Socotra population, the Arabian golden-winged grosbeak becoming R. percivali, and the Somali golden-winged grosbeak R. louisae.
The Abd al-Kuri sparrow is a passerine bird endemic to the small island of Abd al Kuri in the Socotra archipelago of the Indian Ocean, off the Horn of Africa. Though this species was originally described as a distinct species, it was subsequently considered conspecific with the Socotra sparrow. A study by Guy Kirwan showed significant differences from the Socotra sparrow, and that the two sparrows might even have different origins. On the evidence that it is morphologically distinct, BirdLife International recognised it as a species, and it was listed in the IOC World Bird List from December 2009. It has a very restricted distribution, and a population of under 1,000 individuals, so despite not having any known threats it is considered a Vulnerable species on the IUCN Red List.
The Socotran pipistrelle or Lanza's pipistrelle is an endangered species of vesper bat in the family Vespertilionidae. It is endemic to Socotra Island in Yemen, and is the only mammal thought to be endemic to the island.
