“…Los siguientes picos más importantes en el conocimiento de la familia, se enfocan en el trabajo de los especialistas de Apocynaceae para América, cuya actividad se ubica entre 1930 y 1950. Durante este periodo, Woodson proporciona los trabajos más completos sobre el conocimiento de Apocynaceae-Asclepiadaceae y una prolífica descripción de especies nuevas (Woodson 1928a(Woodson , b, 1932a(Woodson , b, 1933(Woodson , 1934(Woodson , 1935(Woodson , 1938(Woodson , 1939(Woodson , 1941(Woodson , 1945, de las cuales, 38 se encuentran como nombres aceptados en México (Tabla 2). También realizó algunos tratamientos regionales, como Flora of North America (Woodson 1938) y The apocynaceous flora of the Yucatan Peninsula (Woodson 1940).…”

Antecedentes: La familia Apocynaceae está entre las 13 más diversas de México y su conocimiento taxonómico ha tenido una atención creciente con la implementación de filogenias y otras herramientas para resolver su sistemática. Con más de 10 años del último listado enfocado en la familia, resulta necesario actualizar el conocimiento sistemático del grupo. Pregunta: ¿Cómo se ha consolidado hasta nuestros días el conocimiento sistemático del grupo en México? ¿Cómo ha cambiado el número de géneros y especies de Apocynaceae en el país y su distribución geográfica por estado? Especie de estudio: Apocynaceae Sitio de estudio: México Método: Revisión de herbarios nacionales e internacionales, bases de datos y una búsqueda intensiva de literatura. Así como colectas en diferentes partes del país. Resultados: Apocynaceae presenta 52 géneros y 418 especies nativas, 204 de ellas endémicas. La subfamilia Asclepiadoideae destaca con 27 géneros y 314 especies. Los estados con más especies y endemismos son Oaxaca, Chiapas, Veracruz y Guerrero. Los estados con más microendemismos son Oaxaca (18 spp.), Chiapas y Jalisco (6 spp.), Baja California Sur y Veracruz (5 spp.). Se proporciona una clave de géneros y un listado actualizado. Conclusiones: Apocynaceae se ubica en el lugar número 12 de las familias más diversas del país. Esto reitera al país como un centro de diversidad del grupo. La integración de más estudios relacionados a la aplicación de herramientas filogenéticas, modelos de distribución y redes de interacción biológica permitirá entender mejor a la familia y proporcionar una historia natural más completa.

“…These three infrageneric classification systems differ as to the composition of each section, have nomenclatural problems, were based only on morphological characters, and have never been evaluated using molecular data. New species have been described by several authors over the years, and many others have been reduced to synonymy (e.g., Woodson, 1939Woodson, , 1948Woodson & Schery, 1940, 1942Gentry, 1974;Markgraf, 1975;Morales, 1996Morales, , 1997aMorales, , 2004aMorales, , 2004bMorales, , 2004cMorales, , 2006Morales, , 2007aMorales, , 2007bMorales, , 2010Morales, , 2011Morales & LiedeSchumann, 2016), adding to the current infrageneric confusion.…”

“…Circumscription of the genus was later expanded by Candolle (1844), who described 17 new species and accepted another 6 previously described by other authors. New species of Rauvolfia were later described by several authors, such as Müller (1860), Markgraf (1924Markgraf ( , 1926a and Woodson (1931Woodson ( , 1937Woodson ( , 1939Woodson ( , 1941. By the middle of the nineteenth century, about 100 species were recognized in the genus.…”

Vinceae comprises 9 genera and about 153 species. The genera differ greatly in a number of morphological traits, especially those relating to fruit and seeds, which resulted in their placement in different tribes and/or subtribes by earlier taxonomists. Here, 378 new chloroplast DNA sequences from 98 species from 5 tribes of the rauvolfioid grade were analyzed phylogenetically to test the monophyly of Vinceae, its 6 subtribes, and constituent genera, as well as the sectional treatments of Rauvolfia, and to find morphological synapomorphies for major clades. Vinceae, as currently circumscribed, was found to be monophyletic as were four of the six subtribes. Kopsia and Ochrosia were confirmed as successive sister groups to the rest. All nine genera currently recognized in the tribe were resolved as monophyletic, Laxoplumeria and Tonduzia for the first time. The broad circumscription of Petchia and Ochrosia proposed by previous authors was supported. The pantropical genus Rauvolfia is divided into two major lineages: one comprised entirely of paleotropical species, and the other the neotropical species, a recurring geographic pattern in the family. Surprisingly, the Hawaiian species of Vinceae have probably arisen by two different trans‐oceanic routes, either by long‐distance dispersal from Australasian (Ochrosia spp.) or Caribbean (Rauvolfia sandwicensis) ancestors. Within Rauvolfia, most of the sections, series and subseries recognized in previous classifications are paraphyletic. Only 2 of the 14 sections of Rauvolfia proposed by Pichon and 1 of the 11 sections proposed by Rao that are not monospecific were found to be monophyletic. Mapping of 30 morphological characters onto the molecular tree identified an unlobed upper wreath on the style head as an unambigous synapomorphy characterizing the tribe as well as synapomorphies for each of its genera. The two earliest‐branching genera, Kopsia and Ochrosia, have dextrorse corolla lobe aestivation, in contrast to the sinistrorse corollas of the other Vinceae and the great majority of genera throughout the rauvolfioid grade. Drupes have arisen in parallel at least three times within Vinceae. The adaptations of the endocarp for water dispersal are possibly ancestral in the tribe, and the observed morphological differences between the drupaceous fruits of Kopsia/Ochrosia versus Petchia and Rauvolfia may be due to their abiotic versus biotic dispersal mode, respectively.
