Résumé:
This work consists in the study of leaf polymorphism in Atriplex halimus, in two
bioclimatic stages of the region of Tebessa.
Initially, a sampling was carried out followed by observations and then comparisons with the
keys for determining the leaves.
The results showed that the species studied presents a great diversity when it comes to the
morphology of the leaves where several forms were recorded, like the followings: obovate,
Orbicular and rhomboidal.
This variable was noticed both at the inter-population level and even at the same individual
level.
The natural ecological areas of the Atriplexes are very vast, and studies on these plants must
be more interested in their diversity in order to find new variants and thus unite the keys of
morphological determination and enrich the databases.
