Comments

The distribution known for Parodia schumanniana (K. Schumann) F. H. Brandt is: Argentina (Misiones), Brazil (Rio Grande do Sul) and Paraguay (Hunt et al. 2006. text: 223) or Paraguay and Northeast Argentina (Anderson 2001, 552). Following the surveys we conducted in Paraguay (Paraguari) and Argentina (Misiones), it is our opinion that P. schumanniana is an endemic taxon of Paraguay, differentiated by morphological characteristics and habitat (see comparative scheme) from the plants, living in the Northeast Argentina in the P. P. Teyú Cuaré, attributed to P. schumanniana by Kiesling (1995, 67:22) and indeed to be identified with Parodia claviceps (F. Ritter) F. H. Brandt. We emphasize that P. schumanniana has probably never crossed the great natural barrier formed by the Rio Paraná, and that if this species shows some affinity, it is with Parodia nigrispina (K. Schumann) F. H. Brandt, the other endemic Parodia of Paraguay. Finally, according to Hofacker (2000, 10: 12), there are no populations of P. schumanniana  in Brazil. (Quoted from Anceschi & Magli 2010, 21-26)

Our deepening on the distribution areas of P. schumanniana is published in “Observations concerning Parodia (Eriocactus)” on The Cactus Explorer 7: 27-39 (2013).
