[2] Rebutia fabrisii is a clustered cactus with globose stems that measure 1 to 2 centimeters in diameter and have fibrous roots.

Its 15 spiral ribs are divided into humps, with almost circular areoles that range in color from white to yellow.

The flowers are red, orange, or yellow, measuring up to 3 centimeters in length and diameter.

[3] This species is commonly found in northern Argentina, specifically in the province of Jujuy around Valle Grande, between Santa Ana and Valle Colorado, at elevations of 1,800 to 3,000 meters, thriving on rocky hills.

[4] Walter Rausch first described Rebutia fabrisii in 1977, naming it in honor of Argentinian botanist Humberto Antonio Fabris.
