Life History:
-
Field plants with unilocular organs released zooids which grew into microscopic thalli. These plants developed in two ways: 1) dioecious gametophytes, which released gametes which fused and produced plants similar to field plants, or 2) plants which recycled directly without sex. At higher temperatures or short days all microthalli recycled directly via zooids (Novaczek and McLachlan 1987; Peters et al. 1987; Peters and Müller 1986a; Ajisaka and Umezaki 1978)
