A reconsideration of the species delimitation in Diogoa (afrotropical Olacaceae)

F.J. Breteler

Research output: Contribution to journalArticleAcademicpeer-review


Strombosia retivenia S.Moore (Olacaceae) from Nigeria, hitherto treated as a synonym of Diogoa zenkeri (Engl.) Exell & Mendonça (Olacaceae), proved to represent a distinct species of that genus. The combination Diogoa retivenia is made. As a consequence Diogoa is no longer monospecific. The two Guineo-Congolese species are geographically separated. Their distributions are mapped. The wide gap in the distribution of Diogoa zenkeri is discussed. Diogoa retivenia, as well as the main distinguishing features of D. zenkeri, are illustrated. A key to the two species is provided. D. zenkeri is lectotypified.
