Dypsis commersoniana (Baill.) Beentje & J.Dransf. (1995:236)
Taxonomy & Nomenclature
Synonyms: Neophloga commersoniana Baill. in Bull. Mens. Soc. Linn. Paris 2: 1173 (1894); Neophloga pygmaea Pic.Serm. in Webbia 11: 149 (1955)
Conservation Status
Missing (Rakotoarinivo & Dransfield, 2012 ["Efforts are required to relocate this species"]) or Extinct [by implication] (Humphreys et al., 2019) (see below)
IUCN RedList status: Data Deficient
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.
