Chrysalidocarpus acuminum Jum. (1922:16)



Taxonomy & Nomenclature

Synonym/s: Chrysalidocarpus acuminatum Jum. (1922:16) [orth. error used by Humphreys et al., 2019]; Dypsis acuminum (Jum.) Beentje & J.Dransf. in Palms Madagascar: 211 (1995); Dypsis acuminatum (Jum.) Beentje & J.Dransf. in Palms Madagascar: 211 (1995) [orth. error used by Humphreys et al., 2019]


Conservation Status

Rediscovered [by implication] (Palmpedia) (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. There is a recent record of the taxon (see Palmpedia), implying that it has been rediscovered.
