Taxonomy:

Life History:

microscopic field plants with uniseriate plurilocular organs bore zooids which gave rise to germlings which grew into microscopic discs. Uniseriate filaments grew from these discs, many of which differentiated into uniseriate plurilocular organs identical to the parent plants. Upon discharge, these organs were replaced with pluriseriate plurilocular organs. The life history appears to be asexual via a direct recycling (Loiseaux 1970b, p. 248)

Phenology:

only plurilocular plants known
