Rapport sur une mission botanique exécutée en 1884 dans la région saharienne, au nord des grands chotts et dans les îles de la côte orientale de la Tunisie

The report records a botanical and zoological survey of southern Tunisia and adjacent eastern coastal islands, describing routes, field methods, and logistical arrangements. It combines inventories of plant and insect species and habitat notes with observations on meteorology, geology, hydrology, and archaeological sites. The narrative details sampling locations, collection and identification procedures, cooperation with local officials and military authorities, and contains annotated species lists and locality records. Practical remarks on climate, terrain, and transport accompany taxonomic determinations and recommendations for further study.
