According to the Edaphology
of the Digital Map of Mexico (INEGI, 2016), Samples 1 and 2 were obtained from a soil belonging to the order of vertisols, which are characterized by having montmorillonite clays, of type 2:1.

This variety is normally a result of biogeographic patterns, modelled by climatology, edaphology
and anthropogenic action (AXELROD, 1983; MANOS & al., 1999, 2001), mainly by the increase in agriculture and forestry, which are the environmental gradients responsible for the hybridization process and the creation of hybrid zones, where populations of two or more related taxa contact to each other and change genetic information (Arnold, 1997; VAZQUEZ & al., 2001).
The collected data revealed that edaphology
and vegetation type are different but topography and anthropogenic affects are somewhat same among sites (Table I) and found some diversity.
(1983) and to the results of edaphic analysis, which in turn has allowed us to elaborate in each plot a compilation of characteristic parameters of their physiography, climate and edaphology
. Twenty-five ecological parameters have been elaborated (four topographical, five climatic and sixteen edaphic) (table II).
