Aylostera mamillosa
species of cactus
Aylostera mamillosa is a species of cactus.
Description
Aylostera mamillosa is a small cactus that grows in clusters with a short taproot. Its stem is dark greenish-brown and can turn purple or bronze when exposed to full sun. The stem diameter reaches up to 2 or 3 centimeters.
The cactus has 10 to 15 ribs, which are divided into prominent tubercles. The areoles on these tubercles produce 12 to 20 radial spines that are 3 to 6 mm long, as well as up to 4 central spines of similar size, all covered with brown wool.
Its flowers are dark red, about 2.5 centimeters across, and feature striking white stamens.
Distribution
The species is native to the deserts and dry shrublands of Bolivia, west of Camargo at elevations around 3300 meters.
Taxonomy
This species was first described as Rebutia mamillosa in 1972 by Austrian botanist Walter Rausch. The name mamillosa comes from the Latin word mamilla, meaning "nipple" or "small protuberance," referring to the tubercles on the stems.

Why this record matters
The phrase “species of cactus” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Stable identifiers, scientific names and standards terminology offer the best bridge between this overview and specialist evidence. The source revision retrieved here is dated Jul 21, 2026. The linked authority identifier is Q92471316. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1972.
A general summary may omit uncertainty, sample limits or methodological disagreement that is explicit in the technical record. 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.
