Resumen:
Background and Aims: One of the most recent approaches to delimiting
plant species is using anatomical wood characters in woody taxa, which
has been little explored in Mexican representatives. The genera
Forestiera is an example of this, since only the wood of two of the 12
species distributed in Mexico have been described. With the aim of
contributing to the knowledge of the wood anatomy of the genera, as well
as the search for anatomical characters that discriminate between their
species, this study describes the wood anatomy of the wood of eight
species of Forestiera distributed in Mexico, with a systematic approach.
Methods: Wood from 42 wood samples from eight species were analyzed,
with three individuals per species at 14 collection sites. The material
was processed with conventional microtechniques to obtain qualitative
and quantitative anatomical variables. Characters were evaluated with
multivariate statistics to determine which ones are important to form
groups of species in Forestiera.
Key results: Some previously reported anatomical attributes agree with
those observed in this paper. However, there are differences such as
semi-ring porous wood and growth marks without marginal parenchyma. The
analyses formed groups of species, based the diameter of early-wood
vessels, length of vessel elements and fibers, diameter of the fibers,
type of rays, abundance of the marginal parenchyma and the type of
crystals in rays. Based on wood anatomy, a taxonomic key is proposed to
identify the studied species.
Conclusions: Through the used analyses, we contribute to the knowledge
of Forestiera anatomy. Wood characters that allow to distinguish groups
of species are recognized. Future studies will confirm their taxonomic
value.
