Summary
1. The ovules ofParnassia nubicola are bitegmic and anatropous. They are tenuinucellate.
2. The megaspore mother cell generally forms a linear tetrad but T-shaped tetrads are also known to occur. Persistence of more than one healthy megaspore is also seen.
3. The embryo-sac isPolygonum-type. Enlargement of antipodals is a common feature. Their number may also increase sometimes.
