Chrysalidocarpus basilongus (Jum. & H.Perrier) Eiserhardt & W.J.Baker (2022:1183)
Taxonomy & Nomenclature
Synonyms: Neodypsis basilonga Jum. & H.Perrier in Ann. Mus. Colon. Marseille, sér. 3, 1: 16 (1913); Dypsis basilonga (Jum. & H.Perrier) Beentje & J.Dransf. in Palms Madagascar: 193 (1995)
Conservation Status
Extinct [by implication] (Humphreys et al., 2019) (see below); possibly Rediscovered (Palmpedia)
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. It has been reported to be extant at the type locality, though without confirmation due to rotten inflorescences (Palmpedia).
