Abstract: This paper reports the studies of overall embryology of Glycyrrhiza uralensis Fisch. Development of the anther wall follows the dicotyledonous type. The cytokinesis of the microspore mother cell in meiosis is of simultaneous type. The arrangement of microspores in tetrad is tetrahedral, isobilateral and decussate. Microspores have various types of abortive to development. Mature pollen grain is of the 2-celled type. The ovule is bitegminous, crassinucellate and campylotropous. The megaspore mother cell gives rise to unequal dyad and then linear tetrad. The chalazal megaspore, the second or the third megaspore towards the micropylar end are functional megaspore. The development of the embryo sac conforms to the Polygonum type. Mature embryo sac has various types of variation. The fertilization belongs to the premitotic type of syngamy. The development of most embryoes belongs to the Onagrad type. The development of the endosperm belongs to the nuclear type and the endosperm near the chalazal end develops into haustorium.
