Life History and Biology:
-
microscopic plants from nature with plurilocular organs bore zooids which did not fuse, but settled to grow into plants like their parents with plurilocular organs. Those kept at 15 C or 20 C failed to form unilocular organs, but those kept at 10 C or transferred from 15 C to 10 C produced unilocular organs Microscopic plants from nature with unilocular organs bore zoospores which did not fuse but settled and grew into microscopic branched filamentous systems of a Microsyphar stage with plurilocular organs. On rarer occasions a more robust plant was formed similar to Hecatonema forming unilocular and plurilocular organs as in nature. It would seem reasonable that these plants were formed from a fusion of a pair of zooids from the plurilocular organs of the Microsyphar stage (Loiseaux 1970b, p. 253)
