Novelties in Oxypetalum (Apocynaceae: Asclepiadoideae): a new species and revalidation of the name O. megapotamicum

Abstract Based on a specimen collected in Santa Catarina state, Brazil, the new species Oxypetalum kassneri is described and illustrated. Moreover, a molecular phylogenetic analysis allows to propose the revalidation of O. megapotamicum, a species currently placed in the genus Ditassa. The neotype o...

Zusammenfassung:Abstract Based on a specimen collected in Santa Catarina state, Brazil, the new species Oxypetalum kassneri is described and illustrated. Moreover, a molecular phylogenetic analysis allows to propose the revalidation of O. megapotamicum, a species currently placed in the genus Ditassa. The neotype of D. megapotamica and the lectotype of D. oxypetala are designated here. Resumo Baseado em um espécime de herbário coletado no estado de Santa Catarina, Brasil, descrevemos e ilustramos uma nova espécie: Oxypetalum kassneri. Além disso, com base em análises filogenéticas moleculares, propomos a revalidação de O. megapotamicum, espécie atualmente circunscrita no gênero Ditassa. O neótipo de D. megapotamica e o lectótipo de D. oxypetala são designados aqui.
