Comments

Gymnocalycium eurypleurum Plesnik ex F. Ritter is the least related to the other populations of the plains, among the Chaco Gymnocalycium. The heart of its distribution area is the P. N. Defensores del Chaco and adjacent areas in the north of the Depto Alto Paraguay (PY), reaching the border with Bolivia (Fortín Palmar de las Islas). In the area of the Cerro León, inside the park, we found the taxon only in the flat area of the deciduous forest (A&M 742, photos 1-21), where it lives in sympatry with Gymnocalycium stenopleurum F. Ritter, which is also located on the hills, together with Gymnocalycium paediophilum F. Ritter ex Schütz. From this area, down to the south west, some populations of the taxon can be found at the P. N. Medanos del Chaco (now joined to the P. N. Tnte Enciso), near the border with Bolivia. Here, in July 2007, we noted with surprise the presence of G. eurypleurum, living in sympatry with Gymnocalycium megatae Y. Itô. (Quoted from: Anceschi & Magli 2013b, 60)
