Bena, Maria Julia, 2017, Typification and nomenclatural notes on twenty-seven names of Gomphrena L. (Amaranthaceae) linked to the South American flora, Phytotaxa 296 (2), pp. 131-146 : 138

Gomphrena martiana var. microcephala Suessenguth (1950: 5)

Suessenguth (1950: 5) mentioned three specimens in the protologue of Gomphrena martiana var. microcephala : “ Argentinien, Prov. Salta, Depart. Oran, Loc. Padre Lozano 270 m. —Leg. M. R. Malvarez nr.444 (2.I.1947); Prov. Salta, Dep. Anta, Loc. General Mollinedo 335 m; leg. M. R. Malvárez nr.603 (15.I.1947); Prov. Salta, Dep. Anta, Loc. General Pizarro; leg. Idem nr. 567 (13.I.1947).- Herb. Tucuman; Herb. München” .

Holzhammer (1956: 233) indicated: “Typus varietatis: Argentinien, Salta, Orán, Padre Lozano, 270 m. s. m., I.1947 (Malvarez no. 444) Herb. München”. On the basis of Art. 7.10, Holzhammer’s designation is to be interpreted as lectotype.

According to Pedersen (1997), Gomphrena martiana var. microcephala was regarded as a synonym of Gomphrena martiana Gillies ex Moquin-Tandon (1849: 400) s.str. The protologue of this latter taxon (l.c.) consists of a detailed diagnosis and the indication: “In prov. S. Luis (Gillies!)”, it is also stated “v.s. in h. Hook” (visa sicca in herbarium hookerianum). Three specimens were traced at E, K, and P, all bearing plant material that matches the diagnosis and corresponds with the current concept in Gomphrena ( Pedersen, 1987; Townsend, 1993). The specimens at K and P bear an inscription that indicates Herbarium Hookerianum. I here designate the specimen K-000634970 as the lectotype of Gomphrena martiana , because it is the most complete regarding plant material. The other specimens are isolectotypes.
