    • Abstract

       

      A detailed cytoembryological investigation inCenchrus glaucus revealed that it is an obligate apomict producing only aposporous embryosacs. Microsporogenesis disclose chromosomal irregularities and megasporogenesis occasionally occur and the development of sexual embryosac is completely absent. On the other hand, aposporous initials develop into 4-nucleate embryosacs. Autonomous development of the embryo is of common occurrence.
