The species name of this variety has been synonymized. According to the nomenclatural rules, a varietal name of a synonymized species name is not available any longer within that species. Although this is nomenclaturally straightforward, it is not always taxonomically. In this case, the author who synonymised the species name did not include any comment about the taxonomic position of the variety. For this reason it is unclear whether the variety has to be included within the proposed legitimate species or whether it should be established as a legitimate variety under that species.
