Note on the Flora of Plane Island (Oran) / Note sur la flore de l’île Plane (Oran)

Abstract

The Oran coastline is a remarkable region cited as a hotspot of plant biodiversity (Véla & Benhouhou 2007). Plane island is the third largest island after Habibas and Rachgoun islands in the Oran region but is less studied. A botanical assessment of Plane island was undertaken in spring 2016. We carried out several phytoecological surveys. We collected and identified ten species in eight families : Chenopodiastrum murale (L.) Fuentes, Uotila & Borsch, Crithmum maritimum L., Cynomorium coccineum L., Frankenia cf laevis L., Limonium pescadense Greuter & Burdet, Malva arborea (L.) Webb & Berthel, Mesembryanthemum crystallinum L., Mesembryanthemum nodiflorum L., Senecio leucanthemifolius Poiret subsp. crassifolius, Suaeda vera Forssk. Ex J. F. Gmel. The identified species list will allow us to follow vegetation dynamics on the island.
