== Description ==
'''Acanthocalycium klimpelianum''' is a small globose cactus species native to Argentina. Plants are typically solitary, occasionally forming small clusters with age. The stem is dark green to gray-green, spherical to slightly depressed, reaching up to 8–10 cm in diameter.

The ribs are low and divided into tubercle-like segments. Areoles are small and bear short radial spines and a few central spines. Spines are thin, straight, and pale, often whitish to light brown.


The ribs are well defined, divided into tubercles. Areoles are rounded, bearing clusters of spines. Spines are stiff, radial spines numbering around 8–12, thin and straight, while central spines (1–3) are slightly longer and more robust.
Flowers are relatively large compared to the plant body, funnel-shaped, typically white to pale pink. They arise near the apex and have a floral tube bearing scales with fine spines, hairs, and bristles.


Flowers are funnel-shaped, relatively large compared to the body, typically pink to magenta with lighter throats. Floral tubes bear scales with fine hairs and bristles. Fruits are small, dry, and dehiscent when mature.
