The embryo sac ofCirrhopetalum fimbriatum is 6-nucleate, generally bisporic, and occasionally monosporic. The reduction of nuclei is due to the ‘strike’ phenomenon. The two chalazal nuclei receive the micropylar polar. The secondary nucleus is triploid, and comes to lie below the egg. The embryo (in ripe seed) is undifferentiated. The cellsca, m, n, andn′ contribute to the embryo. The suspensor is single-celled, hypertrophied and cap-like.
