"J.J. Roemer and J.A. Schultes established the genus Adenium in 1819 and up to 12 species have been described. In the most recent revision by Plazier, only five species are recognized. The genus name is derived from the vernacular name for Adenium obesum, namely Oddaeyn, or "from Aden", where A. obesum was first collected. J.F. Klotzsch described A. multiflorum in 1861 from material collected in Mozambique. The Latin specific epithet refers to the multitude of flowers produced by this plant. In earlier revisions, L.E. Codd considered A. multiflorum as a variety while G.D. Rowley considered it a subspecies of a very closely related but more northerly distributed species, A. obesum. In the latest revision, it was raised to species level again". - Bester (2004)
@bouteloua I suspect that Adenium obesum multiflorum represents a junior synonym of Adenium multiflorum, rather than its current parent taxon. This is admittedly speculative because the POWO lists no synonyms for A. multiflorum.
Unintended disagreements occur when a parent (B) is
thinned by swapping a child (E) to another part of the
taxonomic tree, resulting in existing IDs of the parent being interpreted
as disagreements with existing IDs of the swapped child.
Identification
ID 2 of taxon E will be an unintended disagreement with ID 1 of taxon B after the taxon swap
If thinning a parent results in more than 10 unintended disagreements, you
should split the parent after swapping the child to replace existing IDs
of the parent (B) with IDs that don't disagree.
