Abstract. Oxalis cipoensis, nom. nov. (Oxalidaceae) is herein published as a replacement name for the illegitimate name Oxalis calcicola from Brazil, which is a later homonym of Oxalis calcicola from Guatemala. Keywords: Taxonomy, nomenclature, homonym.
Oxalis L. (1753: 433) comprises about 500 species of Oxalidaceae distributed in both temperate and tropical habitats, from the sea level to elevations of more than 3700 m (Lourteig, 2000). Zuccarini (1832: 200) described Oxalis lunulata (O. sect. Ionoxalis) from Mexico. Later on, Standley & Steyermark (1944: 118) described Oxalis calcicola, from montane areas in Guatemala, which was later synonymized under O. lunulata Zucc. by Denton (1973). While not acknowledging the existence of the name O. calcicola Standl. & Steyerm., Fiaschi (2013) described a new species of Oxalis from the state of Minas Gerais, southeastern Brazil, which he named as O. calcicola Fiaschi (2013: 138). However, this name is illegitimate according to the Article 53.1 of the ICN (Turland et al. 2018), because it is a later homonym of Oxalis calcicola Standl. & Steyerm. Therefore, a new name for O. calcicola Fiaschi is proposed here: Oxalis cipoensis Costa, Sakuragui & Fiaschi, nom. nov. Oxalis calcicola Fiaschi, Britonnia 66(2): 138. 2013, nom. illeg., non
