Inclusion of the endemic New Caledonian genus Pseudosciadium in Delarbrea (Apiales, Myodocarpaceae)

Recent molecular and morphological phylogenetic analyses of the newlyrecognized family Myodocarpaceae (Apiales) have shown that the genus Pseudosciadium (represented by a single species endemic to New Caledonia) is nested within a well-supported clade that also comprises members of the genus Delarbrea, necessitating its inclusion within a more broadly circumscribed Delarbrea. An expanded description is provided for Delarbrea along with a detailed description of the newly transferred species, D. balansae, accompanied by full citation of specimens, an illustration and a preliminary conservation assessment calculated according to IUCN Red List criteria.
