Source-derived summary

Crataegus brachyacantha is one of the "black-fruited" species of hawthorn, but it is only very distantly related to the other black-fruited species such as C. douglasii or C. nigra. The common names blueberry haw and blueberry hawthorn refer to the appearance of the fruit, which are almost blue, and does not refer to their taste. The species is rarely cultivated but has ornamental leaves, flowers, and foliage. It is native to Louisiana, and also occurs just across the border of neighbouring states.

Editorial summary

“Crataegus brachyacantha” enters the record as species of hawthorn. Crown Archives preserves that source wording while asking what Crataegus, brachyacantha and Species can confirm, complicate or overturn.

Editorial reviewUseful for establishing the present vocabulary of the subject while preserving a route back to the evidence on which that vocabulary rests. The current 82-word lead offers orientation but no explicit four-digit date, so chronology should not be assumed. The selected authority fields contribute no independent date. Its strongest next move is a source search built around Crataegus, brachyacantha and Species.
Editorial analysis

Why this record matters

“Crataegus brachyacantha” is worth following because a concise public description often conceals a longer documentary argument. Here, Crataegus, brachyacantha and Species provides the most credible route into that argument.

Evidence profile

Stable identifiers, scientific names and standards terminology offer the best bridge between this overview and specialist evidence. The source revision retrieved here is dated Sep 30, 2025.

Critical limits

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.

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.
