Parodia ottonis
species of plant

Parodia ottonis, also known as Indian head cactus, is a species of flowering plant in the family Cactaceae. This cactus species is found in Argentina, Brazil, Paraguay and Uruguay. There are two recognized subspecies. The epithet ottonis honors the German botanist Christoph Friedrich Otto.
Description
The plant at first grows individually and later forms groups. The light to dark green or blue-green spherical shoots are often tapered towards the base. They reach diameters of 3 to 15 centimeters. The six to 16 distinct ribs are rounded or sharp-edged. There are usually only a few areoles on each rib. The bristle-like thorns that spring from them are straight, curved or twisted.

Why this record matters
“Parodia ottonis” is worth following because a concise public description often conceals a longer documentary argument. Here, Parodia, ottonis and species provides the most credible route into that argument.
Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated Mar 25, 2026. The linked authority identifier is Q1248461. None of the 0 selected statements returned an explicit reference.
Current terminology should not be projected backward without checking the classification used when the underlying evidence was created. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
