Plant phylogeny and inferred ancient polyploidies
Flash marks are used to show polyploidizations, with two zigzags showing tetraploidy, three showing hexaploidy, five showing decaploidy, and a question mark indicating an undetermined ploidy level. The events η and ξ, inferred in the present work, are shown in blue and red, respectively. More ancient events that were inferred to have likely occurred are also shown with question marks.
