The identity of Marsdenia parasita (Apocynaceae, Asclepiadoideae)

Abstract

A neotype is designated for Marsdenia parasita Blanco and lectotypes are designated for its synonyms Dischidiopsis philippinensis Schltr. and Conchophyllum merrillii Schltr. ex Merr. The new combination, Dischidia parasita (Blanco) Arshed, Agoo & Rodda is proposed. We explain why a specimen collected by Llanos and identified by him as Marsdenia parasita is not original material and thus cannot serve as a lectotype. Moreover, this gathering belongs to a different species, Dischidia vidalii Becc. Dischidia bulacanensis Kloppenb. et al. is here treated as a synonym of D. parasita.
