This little member of the Cactaceae family was given this name by Alberto Castellanos in 1950. It is found in the lowlands of Catamarca and Cordoba in northern Argentina, below 500 metres. It is found in slightly acid grit, receiving some water during the summer along with some to lots of sun. The stem will grow to four centimetres high, twice as wide. It is a slow growing species which eventually will form offsets. The flower is white, and might have a red throat.

Considering it is named after Arturo Enrique Ragonese who collected the type specimen, it ought to be G. ragoneseii, however, the sources I use list it with only one "i".
