Comoros
The Comoros also lays claim to the "Îles Éparses" or "Îles éparses de l'océan indien" (Scattered Islands in the Indian Ocean) – Glorioso Islands, comprising Grande Glorieuse, Île du Lys, Wreck Rock, South Rock, Verte Rocks (three islets) and three unnamed islets – one of France's overseas districts. The Glorioso Islands were administered by the colonial Comoros before 1975, and are therefore sometimes considered part of the Comoros Archipelago. Banc du Geyser, a former island in the Comoros Archipelago, now submerged, is geographically located in the "Îles Éparses", but was annexed by Madagascar in 1976 as an unclaimed territory. The Comoros and France each still view the Banc du Geyser as part of the Glorioso Islands and, thus, part of its particular exclusive economic zone.
Léon Humblot
He worked as a gardener for the Muséum national d'histoire naturelle in Paris, then in 1878 embarked on a research trip to Madagascar, where he set up an experimental garden and collected orchid species. In 1884 he entered the Comoros Islands as part of a geographical survey conducted by the natural history museum. In 1885 he procured the signature of a treaty with the Sultan of Bambao, thus establishing a basis for a "Grande Comore protectorate". During the following year, the French had overall rule of the Comoros (Grande Comore, Anjouan, Mayotte and Moheli islands).
