Resumen:
Biogeographic regions are defined by taxa with similar distribution
patterns. Flowering plants have been widely used to propose
biogeographic regionalization schemes because of shared historical or
ecological factors that determine their distribution. The Mexican
Transition Zone represents the boundary between the Nearctic and
Neotropical kingdoms; however, there is no general agreement about the
limits and extent of this region. Despite the significance of its role
in the history of Mexican biota, no study involving a set of relevant
plant taxa validates the magnitude of the Mexican Transition Zone. This
work attempts to determine the proportion of flowering plant families
and genera that characterize the biogeographic kingdoms and the Mexican
Transition Zone. Through identification of distinctive genera it is
shown that the Mexican Transition Zone includes the mountains of Mexico,
from Oaxaca northwards. The results provide a broad view of the
distribution patterns of the flora of Mexico and allow the evaluation of
relationships and floristic affinities.
