FLORISTIC CORTEGE OF THE GENRE LAVATERA A MALVACEAE FOR THE TWO SPECIES: LAVATERA MARITIMA AND L. FLAVA IN THE REGION OF SABRA (TLEMCEN, WESTERN OF ALGERIA)Ghalem Sarra, Hassani Faiçal, Bensouna Amel, Khatir Hadj and Aouadj Sid AhmedAbstract This study is devoted to a phytoecological analysis of the Sabra region of Tlemcen, which is characterized by a high floristic diversity. Our work focuses on the study of malvaceous groups of the genre lavatera (Lavatera maritima and Lavatera flava) in the Sabra region. Our attention has been mainly oriented on the Lavatera of the malvaceae family. The floristic study has allowed us to enrich our knowledge of the existing biodiversity and the similarity that exists between these two genres. The floristic inventory of the floristic cortege of Lavatera maritima counts 31 families and the Eudicots are mostly dominating. The Mediterranean biogeographical type is a predominated one with a percentage of 57%. The floristic inventory of the floral cortege of Lavatera flava has 44 families, with the Eudicot dominating. The predominance species belongs to the Mediterranean biogeographical type (27.90%) with a therophytes dominating in the both species. |
