Cladograms, with bootstrap support from additional analyses indicated. Those (triple bars) supported above the 75% level in at least three of the standard four types of analyses, parsimony of all positions and of ITS-2 only, and distance analyses of all positions or ITS-2 only; and those (double bars) supported above the 50% level in the same analyses. (Bar = 50 changes.) (Left) One of the four most parsimonious trees found by heuristic search using ITS-1 and 2 of the CAGPEV alignment. (Right) Maximum likelihood tree found by heuristic search using ITS-2 positions of the supplemented all-Volvox alignment. Brackets indicate subgeneric groups of Volvox.
