Dypsis rivularis (Jum. & H.Perrier) Beentje & J.Dransf. (1995:232)

 

 

Taxonomy & Nomenclature

Synonym/s: Chrysalidocarpus rivularis Jum. & H.Perrier in Ann. Mus. Colon. Marseille, sér. 3, 1: 40 (1913)

 

Conservation Status

Rediscovered [by implication] (POWO, 2024) (see below)

 

Historically considered extinct by at least one source (fide Humphreys et al., 2019), it was treated as a synonym by Humphreys et al. (2019) and thus not a true extinction, but as the synonymy is homotypic the taxon is still valid. POWO (2024) has a colour photograph taken by Henk Beentje, implying that it has been rediscovered.
