Background:

In Mexico, Apocynaceae is among the 13 most diverse families. The taxonomic knowledge of the family has had increasing attention with the implementation of phylogenies and other tools to solve its systematics. Therefore, more than 10 years after the last list focused on the family, it is necessary to update the systematic knowledge of the group.

Questions:

How the systematic knowledge of the group has been consolidated to this day? Compared to what we knew 10 years ago of Apocynaceae in Mexico, has the number of genera and species changed? Is so, how? And what's their geographical distribution by state?

Species study:

Apocynaceae

Study site and dates:

Mexico

Methods:

Revision of national and international herbaria, databases and an intensive literature search. As well as collecting in different parts of the country.

Results:

Apocynaceae registered 52 genera and 418 native species, 204 of them are endemic. The Asclepiadoideae subfamily contributed 27 genera and 315 species. The states with more species and endemisms are Oaxaca, Chiapas, Veracruz and Guerrero. The states with more microendemisms are Oaxaca (17 spp.), Chiapas and Jalisco (7 spp.), and Baja California Sur and Veracruz (5 spp.).

Conclusions:

Apocynaceae is in the 12th place of the most species diverse families in Mexico. This reiterates the country as a center of apocynaceous diversity. The integration of people interested in the group, the application of phylogenetic tools, distribution models and biological interaction networks will allow us to better understand the family and provide a more complete natural history.
