[2] Rebutia padcayensis has a sprouting growth habit, featuring depressed, spherical bodies that are green to gray-green in color.

The flowers are red with a white throat, orange, or yellow, measuring 3 to 4.5 cm long and wide.

The pericarpel and flower tube are mostly bare, with only 1 to 2 bristles occasionally found at the scale axils.

[3] Rebutia padcayensis is found in southern Bolivia's Tarija department and northern Argentina's Salta and Tucumán provinces, thriving at altitudes between 3000 and 4400 meters.

Walter Rausch first described the species in 1970, naming it padcayensis due to its presence near Padcaya.
