Pterocactus valentinii Here, near El Zampal in the south of the province of Mendoza is a very nice finding place of Pterocactus valentinii. Here is such a specimen of Pterocactus valentinii at the place just mentioned. Distribution of

Pterocactus sp. „Fiambala“ The home of Pterocactus sp. "Fiambala" in the province of Catamarca belongs for many cactus lovers to the most beautiful and interesting landscapes in the northwest of Argentina. This Pterocactus sp. has already been placed to tuberosus, megliolii and gonjianii. But probably it is "neither nor" or "both and". Distribution of

Pterocactus sp. „Rosada“ Unfortunately we only know of this Pterocactus from the province of Chubut on this hill. At first sight this Pterocactus reminds of P. hickenii, but on closer inspection it also shows clear differences. Distribution of

Pterocactus sp. „Neuquen“ North of Chos Malal in the province of Neuquen one of the two known sites is this Pterocactus. At first one thinks that it is a very northern form of Pterocactus hickenii. But then when you see the flowers you think you see a P. fischeri without a flat central spine. Wait - and continue to observe. We hope that we have succeeded in bringing you closer to these small opuntias with their wonderful flowers.
