Environmental changes have been greatly affecting the phenotypic and genotypic characters of plant. These environmental changes affect, as well, the static magnetic force on the Earth which in turn changes the habitats and the taxonomical and physiological characters of the plants. Type of vegetation and species forming communities will be changed and allowed invaded species to compete the local ones. All of these variables beside the variations in climatic and human behavior happened after Covid 19 alters the genetic, taxonomic and phenatic characters of the species and consequently change their taxonomic status. Thus plant taxonomy has to modulate in order to face all these variables and move to new era in classification in response to ecological variables.
