The concept of apogamety and the history of its acceptance are discussed. Apogamety is a special kind of apogamy in which an embryo develops from either synergid (synergid apogamety) or antipode (antipodal apogamety). According to the published information, apogamety is found in 242 species from 79 families of flowering plants, of which 157 species and 58 families belong to the dicotyledons and 85 species and 21 families belong to monocotyledons. Synergid apogamety is encountered in 223 species from 75 families of flowering plants, including 140 species from 56 families of dicotyledons and 83 species from 19 families of monocotyledons. Antipodal apogamety, which is much less frequent, is described in 28 species from 14 families, of which in 14 species from 9 families embryos develop from haploid antipodes, and in 14 species from 5 families they originate from diploid antipodes. Apogamety may also be divided into eugamic apogamety (the development of an embryo from a synergid or antipode after fertilization) and apogamic apogamety (the development of an embryo from these cells without fertilization). The author's data on apogamety in 8 species (Rudbeckia laciniata, Taraxacum alatum, Argyropsis candida, Sternbergia fisheriana, Carya illinoinensis,Cephalaria gigantea, Fragaria ananassa and Hordeum vulgare) are presented.
