Cirsium spinosissimum, common name spiniest thistle, is a European species of thistle which grows in dry rocky areas. It is found in France, Italy, Germany, Switzerland, Austria, and the Balkans.
The plant is between 20 and 80 cm (8 and 31.5 in) tall. Leaves, stems, and the sides of the flower head bear long, sharp spines, hence the name of the plant. Flower heads contain numerous disc florets but no ray florets, the florets off-white sometimes with a purple tinge.
This brief starts where responsible research should: with the source description of “Cirsium spinosissimum” as species of plant. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the science & nature register because the source frames it as species of plant. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Stable identifiers, scientific names and standards terminology offer the best bridge between this overview and specialist evidence. The source revision retrieved here is dated Aug 14, 2026. The linked authority identifier is Q1939175. None of the 0 selected statements returned an explicit reference.
Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. 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.
