Reproductive ecology in a basal angiosperm

Trithuria, the sole genus in the family Hydatellaceae, is an important group for understanding early angiosperm evolution because of its sister relationship to the ancient lineage, Nymphaeales (water lilies). Studying the annual Trithuria submersa, Taylor et al. show that delayed autonomous self-pollination compensates for ineffective cross-pollination by wind, resulting in the evolution of a primarily autogamous breeding system. In contrast to several of its relatives, small size, rapid reproduction and self-fertilization have enabled this tiny aquatic to become a pioneer of ephemeral habitats.
