Gymnocalycium horstii is a distinctive large cactus, minimally spined with a green ball-shaped body. Usually solitary or slowly clustering as they age. Two subspecies are recognized, the nominate form and subsp. buenekeri (Swales) P.J.Braun & Hofacker. The latter was previously considered a good species, genetic studies are required to see if it should be raised to species level again.
