Source-derived summary

Cullen americanum is a plant in the Fabaceae family, found Northern Africa, Italy, Portugal, and Spain, and despite its species epithet, americanum, is an introduced species in the Americas.

It was first described in 1753 as Psoralea americana by Carl Linnaeus, but was reassigned to the genus Cullen in 1919 by Per Axel Rydberg.

Editorial summary

Begin with the source’s own compact description: “Cullen americanum” is species of plant. The dossier treats that line as a proposition to test through Cullen, americanum and species, not as a finished interpretation.

Editorial reviewA sound reference starting point where classification, measurement and the date of the underlying evidence remain visible. The current lead gives the account dated anchors—1753, 1919—that can be checked directly. The selected authority fields contribute no independent date. For this dossier, Cullen, americanum and species is the immediate research focus.
Editorial analysis

Why this record matters

The phrase “species of plant” 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.

Evidence profile

Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated Dec 10, 2025. The linked authority identifier is Q15530798. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1753 and 1919.

Critical limits

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.

How to read it

Check terminology, classification and the date of the cited evidence. Scientific names and technical consensus can change while older records retain historical value.
