Table 2.
(A) MANOVA between two herkogamy traits: style–stamen angle and stigma–anther displacement as dependent variables and lineage (red or blue), population type (pure or mixed) and their interaction as independent variables. (B) Two-way ANOVAs between each of the two herkogamy traits and lineage, population type and their interaction
