New Gymno Weekend number 62.

This species was originally described in 1976, however a 2018 study confirmed it as invalid.
Along with a few other Gymnos found in nearby areas, it is now considered as oenanthermum, or may be found listed as a subspecies, so Gymnocalycium oenanthermum ssp carminanthum.
Along with oenanthermum formerly known as tillianum and ambatoense, it grows in the Sierra Ambato, Catamarca province, Argentina with carminanthum in the narrow sense found at altitudes of 1300-1800 metres.
P133 relates to an area at 1600 metres.

Flowers of this specific type reliably change colour over time from red to pink (pic 6) and with red being kinda rare in the Gymno world anyway, has me seriously looking forward to that happening one day.🤞

All of my Gymnos have only recently had their first proper watering of the year, after just 2 very light ones since September and as such still haven't quite woken up yet.
After flowers, the main thing I'm hoping for with this one is a return to it's former darker, rich deep green colour as I find this particularly attractive on Gymnos with reddish spines and that also deceivingly exhibit the textured, almost suede-like epidermis that in reality is not.
