The embryology of Cordia alba and C. obliqua was studied. The development of the anther follows the dicotyledonous type. The anther wall is four layered in C. alba and four to six layered in C. obliqua. The endothecium lacks fibrillar thickenings in C. obliqua, and the microsporocytes degenerate either during or after meiosis. The pollen grains of C. alba are incompatible. The megagametophyte development is monosporic and conforms to the polygonum type. Occasionally bisporic development occurs Multiple megasporocytes and multiple dyads are common Megaspore tetrads are always linear in C. alba and linear, T shaped, or isobilateral in C. obliqua. A tendency toward apospory was observed. In C. obliqua the aposporic embryo sac develops to the eight-nucleate stage and shows an organization similar to that of the normal megagametophyte. The normal gametophyte degenerates whenever the aposporic embryo sac reaches maturity There is no fruit set in C. alba.
