Abstract
ABSTRACT The embryology of Clitoria ternatea was studied. Anthers contain four sporangia. The anther wall comprises an epidermis, an endothecium, a middle layer and a glandular tapetum. Microspore tetrads are tetrahedral and pollen grains are shed at the 2-cell stage. The ovule is campylotropous, bitegmic and crassinucellate. The micropyle is formed by both the integuments. The megaspore tetrad is linear or T-shaped. The chalazal megaspore is functional and embryo sac development follows the monosporic Polygonum type. Endosperm development is of the nuclear type. The chalazal part of the endosperm forms a haustorium. Embryo development follows the Onagrad type.
