<p><strong><em>Matelea ojadapantha </em></strong><strong>(Apocynaceae; Asclepiadoideae; Gonolobeae; Gonolobinae), a new species from México</strong></p>

Abstract

A new species of Matelea from central and southern México with green to black corollas and pubescent lobes is described here: Matelea ojadapantha. This taxon is morphologically similar to M. schaffneri and M. atrostellata but differs by the corolla and corona morphology and has a disjunct geographic distribution. Descriptions, illustrations, morphological comparisons, map of the distributions of this species as well as their conservation status is provided. This discovery highlights México as a center of diversity of the genus, as more than 70 species are currently known in the country. Furthermore, 60% of those species are endemic.

A New Species of Matelea (Apocynaceae, Asclepiadoideae) from the Península de Nicoya, Guanacaste, Costa Rica

“…Nevertheless, though some characters have been useful to delimit clades, more evidence and documentation, including stronger phylogenetic hypotheses, are still necessary (McDonnell et al, 2018). Despite the lack of monophyly of Matelea s.l., several new species have been described following the traditional circumscription of the genus (Cortez et al, 2018; Alvarado-Cárdenas et al, 2020; Jiménez & Hidalgo-Mora, 2021; Juárez-Jaimes et al, 2021).…”
