REVISIÓN DEL GÉNERO Bourreria P. Browne (Boraginaceae) EN MÉXICO

Abstract

Mexico is a major center of diversity of the
genus Bourreria but the identity and
taxonomic status of several species were
still uncertain in the absence of revisions.
The taxonomic account presented here is
based on morphology. It relies on extensive
field surveys of native populations and on
the study of relevant herbarium material.
Original descriptions, nomenclatural types,
selected synonymy, distribution and habitat
requirements are provided for each species.
Comments and notes are added on various
aspects of the species. Sixteen species of
Bourreria occur in Mexico, endemic to a
small area and six new species are proposed.
A key to species, illustrations and
distribution maps are also provided. In
addition, to propose the lectotypification
for three species.
