Abstract
Many anatropous tenuinucellate and bitegmic ovules are present in the trilocular ovary ofIndotristicha ramosissima (Wight) van Royen andDalzellia zeylanica (Gardn.) Wight. The two integuments in both species originate simultaneously. The four nuclei present in the organized embryo sac are derived from the primary micropylar nucleus of the two nucleate embryo sac. Development and organization of the female gametophyte conforms to the Apinagia type, form B. The organized embryo sac has two synergids, an egg and a polar cell; there are no antipodal cells. Forms C and D of the Apinagia type do not exist in the family. Organization of the nucellar plasmodium occurs after fertilization.
