Discussion		Plants with more than 10 heads of 3–12 flowers have been separated as Juncus phaeocephalus var. paniculatus Engelmann. This variety is very similar to the neext species (Juncus macrandrus) and is probably better treated as part of that species. Until a more thorough study has been made of the entire subgenus, we are hesitant to make such a transfer. (Discussion copyrighted by Flora of North America; reprinted with permission.)
