Resumen:
Los Tuxtlas Region in the Veracruz state has approximately 2,548 species
of vascular plants, this is why it is considered one of the areas with
largest floristic diversity in the state. The Asclepiadoideae subfamily
(Apocynaceae) contributes substantially to the richness of the vascular
flora of the area. In this study we estimated the number of genera and
species of the subfamily and provide the keys for taxonomic
determination of genera and species, as well as morphological
descriptions, distribution maps of the species, and data on their
habitat and phenology. Twenty-one species and 13 genera are registered.
The genera with more species are Marsdenia with 5, Gonolobus with 4,
followed by Asclepias with 2, whereas 10 genera are represented by a
single species: Bruceholstia, Cynanchum, Dictyanthus, Fischeria,
Funastrum, Macroscepis, Metalepis, Orthosia, Oxypetalum, and Vailia.
Three new records for the region are reported: Marsdenia rzedowskiana
Juarez-Jaimes et W.D. Stevens, Marsdenia hiriartiana Juarez-Jaimes et
W.D. Stevens, and Gonolobus pallidus W.D Stevens. This records update
the knowledge of the group in the region.
