Panax wangianus S. C. Sun (Araliaceae) is a critically endangered, medicinal plant of north-east India. The objective of this research was to study post-fertilization changes in embryo-sac of P. wangianus. A characteristic feature has been observed in the endosperm in P. wangianus in which both the nuclear and cellular endosperm remains together in the mature seeds. The embryo is present in the nuclear part of endosperm so that it can draw the nutrition easily. The embryo probably exerts some physical and physiological forces that prevent the nuclear endosperm to become cellular.
