Abstract

Criteria obtained by SEM of seed coat surface have been used to re-assess the taxonomic relationships between
19 species belonging to three subgenera of the genus Sesbania. The produced characters were analyzed by the
NTSYS-pc. program package using the UPGMA clustering method. The produced phenogram supported the
treatment of the three taxa Agati, Daubentonia and Sesbania as subgenera in the genus Sesbania. SEM criteria
have revealed that, the genus represent a natural monphyletic group and the subgenus Sesbania is the center of
the genus from which the other subgenera could have been evolved.
