Abstract

Twelve species of wild leguminosae were studied to determine similarities in the coat details of the seeds using a Scanning Electron Microscope (SEM). The numerical cluster analysis method was used to examine the morphological characteristics (98 characteristics) and to clarify the taxonomic relationship between the studied species (6 genera and 3 tribes) belonging to the Fabaceae family. The relevant wild species were: Lotus edulis L, Lotus ornithopodioides L., Tetragonolobus purpureus Moench, Medicago laciniata (L.) Mill., Gard. Dict., M.orbicularis (L.) Bart., M.turbinata (L.) All, M.polymorpha L., Ononis vaginalis Vahl, Lathyrus aphaca L., Vicia sativa L., V. peregrine L., and V.tetrasperma (L.) Schreb. The aim of this study was to produce a taxonomy reflecting the relations between these twelve forage species of Fabaceae by using the morphological and SEM features to provide a details about and clarify the relations between the examined taxa. The taxonomic histories of the Fabaceae family were reviewed. The results of the morphological description and SEM showed that it was possible to distinguish between the taxa using the cluster analysis attributes for the differences in characteristic correlation between the groups under study. This study will help researchers better grasp the classification of these species of legumes which were chosen because of the difficulty of differentiating between them, their environment benefits, their use for human consumption and pasture. The SEM is a suitable tool for this analysis, owing to the similarities exhibited by the seeds. CI Р© 2021 The Author(s).
