Gomphrena elegans var. mandonioides Suessenguth (1934: 310)

Suessenguth (1934: 310) mentioned two specimens in the protologue of Gomphrena elegans var. mandonioides : “ Peru, Mantaro-Tal. Depart. Huanca-velica, Prov. Tayacaja, unterhalb Colcabamba, 2200 m (A. Weberbauern 6443).- Sorata, 2600 m, VIII. 1926 (C. Troll, Iter andinum n. 2412)”. I traced two sheets referring to these syntypes (see Art. 9.5): the first one at M (code 0241725) collected by C. Troll and other sheet at GH (code 00037073) collected by A. Weberbauer. Both specimens match Suessenguth’s diagnosis and bear labels reporting Suessenguth’s scripts. The GH specimen is more complete and, therefore, it is here designated as lectotype of Gomphrena elegans var. mandonioides . According to Jorgensen, et al. (2014) Gomphrena elegans var. mandonioides is a synonym of Gomphrena mandonii . The latter name was published by Fries (1921: 22) through a detailed diagnosis and the citation of a specimen: “ Bolivia: Prov. Larecaja, viciniis Sorota in schistosis dumosis cultis et undique, reg. temp. 2600–3200 m. s. m. [Aug. 1859 – Apr. 1860.— MANDON n. 1016; in herb. Regnell]”. I have traced 11 specimens of this collection housed at BM, G, GH, K, M, NY, P, PH and S-R, which are all part of the original material. The specimen S-R-2445 bears a stamp with the name “Herb. Typ. Regnell” and bears a label with Fries determination. Therefore I designate it here as lectotype of the name Gomphrena mandonii , the other specimens are isolectotypes.

Additional material seen:— BOLIVIA. Dept. La Paz. Sorata, 2600 m, 28 August 1926, Troll 2412 (M-0241725!).
