Comments

Our idea of Gymnocalycium anisitsii (K. Schumann) Britton & Rose includes Gymnocalycium damsii (K. Schumann) Britton & Rose, as already identified by Anderson (2001, 349; 2005; 2011). The fusion between the populations of the two taxa occurs in the transitional area between Puerto Casado, Puerto Risso (Paraguay) and Puerto Murtinho (Mato Grosso do Sul, BR). The taxon known as Gymnocalycium damsii ssp. multiproliferum P. J. Braun or Gymnocalycium anisitsii ssp. multiproliferum (P. J. Braun) P. J. Braun & Esteves is in our opinion a transitional form between G. anisitsii and G. damsii (A&M 267, photos 55-74). Conceived in this way G. anisitsii is in the genus Gymnocalycium, the dominant species in the east of the Chaco Biome, in an area which stretches from the city of Concepción (Paraguay), through the Dept. of Concepción, Pte Hayes, Alto Paraguay in Paraguay and the State of Mato Grosso do Sul in Brazil, to the areas populated by the taxon of the Bolivian Chaco, in the Dept. of Santa Cruz in Bolivia, which includes the Serranias de Santiago and de Chiquitos and the Valle de Tucavaca, in the extreme tip of the Chaco, to the north. In this regard, as a result of the surveys in habitat, we think that part of the populations of G. anisitsii are Gymnocalycium pseudomalacocarpus Backeberg (not valid published), a taxon attributed in recent literature to Gymnocalycium marsoneri Fric ex Y. Itô (Anderson 2001, 355), to Gymnocalycium marsoneri ssp. matoense (Buining & Bredenroo) P. J. Braun & Esteves (Hunt et al. 2006 text: 132; Anderson 2011), or to Gymnocalycium marsoneri ssp. megatae (Y. Itô) G. Charles (Charles 2009, 244-245, 287), and also Gymnocalycium anisitsii ssp. holdii Amerhauser, which Charles considered a synonym of G. marsoneri ssp. megatae (2009, 244-245, 287). As can be seen from the observation in the Valle di Tucavaca, Santa Cruz, BO, (A&M 704, photos 1-54), all of these forms, including the one known as Gymnocalycium damsii var. rotundulum Backeberg, live in the same population of G. anisitsii.
