Numerical investigation within the genus a triplex

الملخص EN

70 morphological characters were used as Operational Taxonomic Units (OUT's) in a study of seventeen A triplex species.

The clustering analysis shows three groups: The first group contains both A.

patula and A.

hastatea, while the second gathered the species, A.

nummularia, A.

inamoena and A.

polycarpa.

The rest of the studied species have been clustered together in a third group.

Three subgroups have been identified within this last group.

The result has been discussed according to their morphological characters.

A key for the studied species is also provided.
