Gomphrena viridifolia Suessenguth (1934: 316)

The protologue of Gomphrena viridifolia ( Suessenguth 1934: 316) consists of a short diagnosis which was followed by the indication of four specimens (syntypes, Art. 9.5): “ Uruguay, Départ. Canelones, Toledo, V. 1927 (Herter, PI. Uruguay, n. 929 [81881]; Herter , PI. Uruguay, n. 811 [81890].—Argentinien, Prov. Tucuman, Quebrada do Lules , 550 m, V. 1929 ( S. Venturi n. 9055).—Prov. Buenos Aires, Dock Sud , V. 1926 ( L. R. Parodi 7241)” .

Holzhammer (1956) indicated as “typus” of Gomphrena viridifolia the Herter’s collection no. 929/81881, which is actually preserved at M (code 0241814). On the basis of Art. 7.10, Holzhammer’s indication should be interpreted as lectotype.

According to Pedersen (1987), Gomphrena viridifolia was regarded as a synonym of Gomphrena elegans Martius (1826a: 17) , synonymyzation that is here supported.
