'''Acanthocalycium ferrarii''' is a small globose cactus species native to Argentina. Plants are usually solitary, with dark green stems and well-defined ribs.
'''Acanthocalycium ferrarii''' is a small to medium-sized cactus, usually solitary, with globose to short cylindrical stems and a green to grey-green epidermis.


The ribs are typically low and rounded. Areoles are small and spaced along the ribs. Spines are short to medium in length, usually grayish with darker tips. The number and length of spines may vary depending on growing conditions.
* '''Ribs''': 10–15, well defined, slightly tuberculate
* '''Areoles''': Regularly spaced, with short wool when young
* '''Spines''': Numerous, straight; radial and central spines present; colour variable from pale grey to brown
* '''Flowers''': Diurnal, subapical; funnel-shaped; white to pink or yellowish; floral tube with spiny scales
* '''Fruits''': Spherical, dry; dehiscent
* '''Seeds''': Dark, papillose


Flowers are relatively large compared to the body, funnel-shaped, and commonly yellow, though variations may occur. The floral tube bears scales, hairs, and bristles typical of the genus.
