Fruit of several journeys to Socotra, this small work is intended for travellers and the Succulent plant collectors of this magic island, because it claims to illustrate almost the totality of the known species on Socotra, and because it will allow to identify them on the spot, indicating the main places which we may visit. A practical index ends the work. Simple guide of identification, very useful for the tourist, half of the published copies will be offered to the Association of the Socotran Women.
