Abstract
Jasminanthes xuanlienensis (Apocynaceae, Asclepiadoideae), a new species from Vietnam is described, illustrated and compared with its five congeners. Jasminanthes xuanlienensis differs distinctly from congeners by the longer peduncles (14–18 cm vs. 4 cm at most in Jasminanthes pilosa and Jasminanthes saxatilis, salmon-pink color of the inner corolla lobes (white or greenish in the other species), and corolla tube length (12.0–14.5 mm vs. shorter or longer in congeners).
Highlights
Jasminanthes Blume (Apocynaceae, Asclepiadoideae, Marsdenieae) is a small Old World genus of six species (Endress et al 2014)
Jasminanthes is separated from Marsdenia based on its large flowers (>15 mm long) with salverform corolla and by its inconspicuous to absent staminal corona
In Vietnam, no species of Jasminanthes have been recorded to date (Ho 1993, Tran 2005)
