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 : 133

Gomphrena elegans var. claussenioides Suessenguth (1934: 310)

Holzhammer (1956) indicated the specimen “ P. G. Lorentz & G. H. Hieronymus 705” as “ typus varietatis”, but this was in fact a lectotypification since the protologue mentioned two specimens (see Art. 7.10): “ Argentinien, Sierra de Tucuman, La Cienaga, I. 1874 (G. Hieronymus et P. G. Lorentz, Flora Argent. n. 705). Paraguay, Tobati, bei Cerro Aparepy. Toniger Camp. Vulgärname „Batatilla “ wegen der batatenähnlichen Wurzelknolle (K. Fiebrig. PI. parag. n. 796)”.

Suessenguth’s types are mainly housed at M, but this particular collection was not traced, neither at M nor at B. Actually, there are duplicates of this collection at GOET (code 015489) and CORD (code 00002558) but none of both specimens bear an indication that Holzhammer has examined it. Considering the Art. 9.17, Holzhammer’s indication should be narrowed to one single specimen in a subsequent lectotypification. According to Stafleu & Cowan (1981), Lorentz types are housed at GOET, therefore the specimen GOET-015489 is designated here as a second-step lectotype of the name Gomphrena elegans var. claussenioides .
