| Abstract: | Embryo development in Leiothrix nubigena, Paepalanthus bifidusand Syngonanthus nitens is described. Distinct differentiationof cotyledonary and epicotyledonary sectors in the three taxais demonstrated. The cotyledonary and the epicotylary loci shareequal amounts of the embryonic shoot apex as in most monocotyledons.The cotyledon and its adjacent epicotyl are both terminal onthe embryonic axis. The basal cell of the two-celled proembryocontributes two basal rows of cells at the radicular pole inthe ripe seed. A typical radicle is not organized.
