The floristic composition, morphometric and the adaptation of a new species: Malva subovata in the matorral of Algeria (Djbel fellaoucen)

This study is based on a ruderal species: Malva subovata = Lavatera maritima which should normally grow in the littoral, under maritime influence. Its presence matorrals highlighted for first time. as it has been found far from its natural habitat. The comparison of different biological and morphological spectra shows importance therophytes that confirms phenomenon degradation. degradation depletion floristic procession, especially concerning sylvatic species have given way to ephemeral chamæphytes. Despite shrubby layer, no longer question forest ecosystem but pre-forest ecosystem. To better understand characteristics this Malvaceae terms resistance adaptation matorrals, we often use phytomass all anthropozoic formations more specifically characterize group. In our case, subovata. results morphometric constitute basic element evaluation adaptive potential Lavatère against factors.
