Glossary of Plant Systematics (1st ed.) by Simpson (2006)

  • A type of tetrasporic female gametophyte in which three of the four megaspores fuse to form a triploid nucleus, followed by two sequential mitotic divisions of the haploid and triploid nuclei, resulting in an 8-nucleate female gametophyte in which the three antipodals and one of the polar nuclei are triploid, the outer polar nucleus and the cells of the egg apparatus remaining haploid.
