    A new species of Sarcostemma (Apocynaceae-Asclepiadoideae-Asclepiadeae) from Yemen
    (2011) Bruyns, P V
    Sarcostemma areysianum Bruyns is described from the southern mountains of Yemen. It appears to be most closely related to S. arabicum Bruyns & P. Forst. and S. socotranum Lavranos, differing from both by the taller gynostegium with narrow, mostly acute inner corona lobes. A key to the species from Arabia and Socotra is provided.

    The rediscovery of Schizostephanus gossweileri and its phylogenetic position
    (2009) Bruyns, P V; Klak, C
    Two new records of Schizostephanus gossweileri (S. Moore) Liede from north-western Namibia and south-western Angola are documented and an amplified description is provided for the species. Analysis of ITS and trnL–F data provides additional evidence that this species belongs to Schizostephanus Hochst. ex K. Schum., where its relationship to S. alatus is strongly supported. The two species of Schizostephanus form a lineage that is either unsupported or weakly supported as sister to Cynanchum L. s.l.
