Is Justicia mollissima (Nees) Y.F. Deng & T.F. Daniel (Fl. China 19: 451–452 2011) is legitimate as per ICN 2012 ?
Basionym - Rostellaria mollissima Nees (Pl. Asiat. Rar. 3: 101 1832).
Because, Wallich published Justicia mollissima as nom. nud. in Numer. List. no. 2445. 1830.
Also, Nees cited Justicia mollissima Wall. as synonym under Rostellaria mollissima Nees (Pl. Asiat. Rar. 3: 101 1832).
So it can be, Justicia mollissima Wall. ex Nees (Pl. Asiat. Rar. 3: 101 1832), but this name may be illegitimate, cited as synonym under Rostellaria mollissima Nees (Pl. Asiat. Rar. 3: 101 1832).
My question is for nomenclatural experts -
From three names which one is legitimate as per ICN 2012 and why.
1. Justicia mollissima Wall. (Numer. List. no. 2445. 1830).
2. Justicia mollissima Wall. ex Nees (Pl. Asiat. Rar. 3: 101 1832).
3. Justicia mollissima (Nees) Y.F. Deng & T.F. Daniel (Fl. China 19: 451–452 2011).
