Androecium phyllotaxis

Fig 3.9 Selected floral characters mapped on the hackhone tree of Doyle and Endress (2010) with fossil Cohongarootonia hispida (PP53716) included. (A) Androecium phyllotaxis. (B) Androecium merism. [Pg.66]

Based on our data set, there are no unequivocal changes in floral characters on the line from the base of the mesangiosperms to the common ancestor of Canellales and Piperales. If mesangiosperms originally had a trimerous androe-cium, as inferred when phyllotaxis and merism are treated as separate characters, there was an increase in the number of stamens per whorl in Canellales (i.e. the androecium became polymerous), followed by connation of the stamens into... [Pg.108]
