Life History:
direct development with possible suppression of meiosis in unilocular sporangia; blades bearing both unilocular and plurilocular sporangia; zooids from both types developing identically, each capable of producing a blade immediately or after a succession of discoid and filamentous plethysmothalli capable of recycling by zooids from unilocular or plurilocular sporangia.

plurilocular sporangia found only in the north
