Geographic coordinates and the altitude of the collecting site were used to discrimate several accession groups from the analysis of principal components and conglo- merates through the “Ward’s” method, using the Flo- raMAP package (Jones, Guarino, & Harvis, 2002). The different groups were defined according to the altitude and climatic environment of the site of origin (total an- nual rainfall, rainfall distribution and air temperature changes along the year).
