Notoceras bicorne (Aiton) Amo (1873: 536)

≡ Erysimum bicorne Aiton (1789: 394) [basionym]

Type (lectotype [or perhaps holotype], indicated by Jafri (1973: 194) as “type”):— Spain, Canary Islands, Francis Masson s.n., 1778 ( BM, barcode BM000583715 ) ( Fig. 1 ) .

= Diceratium prostratum Lagasca (1816: 20)

≡ Notoceras hispanicum Candolle (1821: 204) , nom. illeg. (Art. 52.2 (e) of the ICN, see Turland et al. 2018)

≡ Notoceras bicorne β [var.] hispanicum Willkomm (1880: 827) (see ICN Art. 58.1)

≡ Notoceras bicorne var. prostratum (Lag.) Pau (1931: 148) , nom. illeg. (ICN Art. 52.1) 1

Type (neotype, designated here):— Spain, Orcelis [Orihuela, Alicante province], 1819, Lagasca 7 (G-DC, barcode G00149955 ) ( Fig. 2 ) .

1 Notoceras bicorne var. hispanicum is not illegitimate under ICN Art. 58.1 (see Ex. 3) ( Turland et al. 2018). Furthermore, it makes illegitimate the homotypic combination N. bicorne var. prostratum (Lag.) Pau (1931: 148) published 51 years after Willkomm’s one that takes priority at varietal rank being a replacement name.
