Notes
editorial
authority Vaill. not Hill see Greuter et al. 2005: "Sébastien Vaillant relevant works (Vaillant, 1719–1725) appeared long before the starting point date of botanical nomenclature (1 May 1753) and names appearing therein, unless taken up by later authors, have no standing under the International Code of Botanical Nomenclature (ICBN; Greuter & al., 2000). There is, however, a German edition of these papers (Vaillant, 1754) to which this limitation does not apply."
