Three new species of Marsdenia (Apocynaceae) from Brazil

Abstract

Th ree new species of Marsdenia (Apocynaceae) are described from Brazil: M. paganuccii, known from two disjunct populations, one in the Caatinga of Bahia and other in the Atlantic Forest of Espírito Santo; M. paraibana, restricted to the Restinga of Cabedelo National Forest in the Atlantic Forest of Paraíba; and M. trisegmentata, known from two populations in Caatinga, one in Bahia and other in Ceará. Illustrations, a geographic distribution map and comparisons with morphologically similar species are also presented for each species.

Survey of the apocynaceae family in the state of Pernambuco, Brazil deposited in Recife herbaria

“…Recent studies have reported the discovery of new species of Apocynaceae in the region, such as Marsdenia paganuccii, Marsdenia paraibana and Marsdenia trisegmentata (Santo, 2018). In the state of Bahia genera like Allamanda, Catharanthus, Thevetia and Plumeria have been recorded (Nascimento;Coelho, 2016).…”

“…However, these taxonomic treatments are not fully supported by the current molecular phylogenies (Endress et al 2014). Some new taxa of this genus have been discovered and described in recent years (Stevens and Juárez-Jaimes 1999, Juárez-Jaimes and Alvarado-Cárdenas 2010, Rapini and Pereira 2011, Fernando and Rodda 2013, Jaimes 2015, Jaimes and Pérez 2015, Jaimes and Saynes 2015, Carnevali et al 2016, Stevens et al 2016, Santo et al 2018a, 2018b. According to the treatment of Marsdenia in Flora of China, there are 25 species recognized in China and mainly distributed in the east, south and southwest provinces (Tsiang andLi 1977, Li et al 1995).…”
