BIOSYSTEMATIC STUDIES OF BASSIA MURICATA COMPLEX

摘要

Bassia mu r icata (Chenopodiaceae) is a polymorphic species. The present study has been carried out on the different races distributed in Northern and Eastern Egypt. The study based on morphological and anatomical characters, in addition to SEM investigations of both pollen grains and seed coat sculpture, revealed the presence of four distinct races which are dealt here as varieties. Two of them, var. hadidii and var. sinaica are recorded to the first time (varieties nova).
