Gomphrena acrotepala Suessenguth (1934: 308)

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 : 132

Gomphrena acrotepala Suessenguth (1934: 308)

Suessenguth (1934: 308) gave a detailed diagnosis of Gomphrena acrotepala , and he also mentioned two collections: “Argent. septentr. 111. 1906 (I. S. Urriche-R. Hauthal, P. Rioja; Herb. Berlin). - Argent.: La Diana (Th. Stuckert n. 17218; Herb. Delessert, Genf)”. Holzhammer (1956: 233) indicated “Typus: Nord-Argentinien, La Rioja, III.1906 (Urriche et Hauthal) Herb. Berlin”. This indication is to be considered as valid, but on the basis of Art. 7.10 of the ICN ( McNeill et al. 2012), it should be interpreted as lectotype.

I agree with Pedersen (1990: 74) in synonymizing Gomphrena acrotepala with Gomphrena boliviana Moquin-Tandon (1849: 401) which has nomenclatural priority. The latter name was published by Moquin-Tandon (l.c.) through a detailed diagnosis; the author also listed one specimen [“Culta in hort. Luxemb. aug. 1836 e seminib. Bolivianis (Gay!)”]. At the end of the description the author also stated “v.s. in h. Webb.” (visa sicca in herbarium Webbianum). I traced one specimen collected by Gay at FI (the Webb’s collection is deposited at the Florence Herbarium only - Stafleu & Cowan, 1988: 118). This specimen is here considered as the holotype of the name Gomphrena boliviana .
