Which Joe gave his name to ‘sloppy joes’? We look at five interesting sandwiches and their lexical origins.
[mass noun] Asexual reproduction in which seeds are produced from unfertilized ovules.
- ‘Seeds are not produced without fertilization (absence of agamospermy).’
- ‘Both species use a mixed breeding system, consisting of xenogamy, geitonogamy, and autogamy; agamospermy is unimportant.’
- ‘Asexual seed production, agamospermy, occurs in >40 flowering plant families but is most prevalent in the grasses, Asteraceae, and Rosaceae.’
- ‘None of these species set seed through agamospermy or autonomous self-pollination; therefore they depend entirely on pollinating agents for their reproduction.’
- ‘Within the genera that develop bisexual flowers, agamospermy appears to be present in Sarcandra chloranthoides as well as Chloranthus serratus and C. fortunei.’
- ‘In the bagged experiment, fruitlet formation was never observed, suggesting that no agamospermy takes place, and that pollination is critical for fruit set.’
1930s: from Greek agamos unmarried + sperma seed.
