Taxonomy:
Wynne 1969a Display references
Life History:
uprights macroscopic tubular plants with unilocular organs bear zooids which germinate to form a filamentous basal system. Uprights similar to parent plants grow from this basal system and bear unilocular organs. Other, much less common plants, of a more contorted morphology also occurred in culture. These plants bore plurilocular organs, and recycled directly. No sex has been found in this life history (Wynne 1969a, p. 45; also see Pedersen 1984) Display references
Phenology:
plants are exclusively unilocular in the south, and unilocular and plurilocular in the north on separate plants (specimens seen by DeCew at UBC; also see Edelstein et al. 1970 for Atlantic plants) Display references
