Biplots of the first two axes of the RDA ordinations of 32 populations of Embothrium coccineum; included are the explanatory variables that appeared to be significant (P < 0·05) determinants of variation in (A) leaf and (B) flower morphology. The explanatory variables are described in Materials and Methods and their values in Appendix 1. The eigenvalue associated with each axis is provided in parentheses. Open circles are the populations occurring on the western slope of the Andes (Chile) and closed circles the populations on the eastern slope of the Andes (Argentina). Full names for population acronyms are given in Appendix 1.
