Popis:	Embryo development in Leiothrix nubigena, Paepalanthus bifidus and Syngonanthus nitens is described. Distinct differentiation of cotyledonary and epicotyledonary sectors in the three taxa is demonstrated. The cotyledonary and the epicotylary loci share equal amounts of the embryonic shoot apex as in most monocotyledons. The cotyledon and its adjacent epicotyl are both terminal on the embryonic axis. The basal cell of the two-celled proembryo contributes two basal rows of cells at the radicular pole in the ripe seed. A typical radicle is not organized.
