    ABSTRACT
    Malva subovata (DC.) Molero & J.M. Monts. (= Lavatera maritima) (Malvales Malvaceae) is considered a plant resistant to ecological stress and also to human action. The objectives of the present study were to characterize the biogeography and localization of M. subovata. The maps which have been drawn up show us the different formations inventoried and which are dominated by lawns with perennial and annual species and which are due to the degradation of the tree formations. The map we produced shows that our species is located in six large regions and it allowed us to have a global idea of its current distribution.

    ABSTRACT
    The vegetation of the region of western Algeria presents a good example of the study of phyto-diversity. The method of floristic analysis is a main element in the knowledge of natural environments and its rich flora. In my two stations, we carried out floristic surveys, these are a set of observations on the environment and on the vegetation. The study presented is only a part of the objectives of the Laboratory of Plant Ecology focused on the floristic diversity of Malva subovata (DC.) Molero & J.M.Monts. (Malvales Malvaceae) on the mastery of the biological, morphological and phytobiogeographic capital of the two stations “Boussdra and Hammam Boughrara” in the Tlemcen region. From the treatment of biodiversity indices and the floristic surveys, we were able to conclude that the study area is undergoing a regressive dynamic of vegetation.
