Gymnos in habitat
Gymnocalycium spegazzinii Britton & Rose
The habitat of G. spegazzinii spans over the Argentinian provinces of Salta,
Tucaman and Catamarca. This widespread species is highly variable and can be
found in heights of 1550 to 3350 metres. Strongly spined plants growing
pillar-like in old age were described by Backeberg as G. spegazzinii var.
major. These forms grow south of Cachi and in the south-west of Molinos.
The prettiest plants - in my opinion - grow north-east of Cafayete; they
were described as G. spegazzinii var. punillense.
