Source-derived summary

Myrcia guianensis (pedra-ume-caá) is a species of plant in the genus Myrcia of the family Myrtaceae native to South America.

This species shows allelopathic effects on germination and radicle and hypocotyl growth of weeds. Isolated compounds related to this inhibition are gallic and protocatechuic acids.

This species is found in association with endophytic fungi.

Editorial summary

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

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 54-word lead offers orientation but no explicit four-digit date, so chronology should not be assumed. The selected authority fields contribute no independent date. For this dossier, Myrcia, guianensis 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

The date and method of observation matter as much as the stated conclusion, especially where classification or consensus has changed. The source revision retrieved here is dated Nov 30, 2025. The linked authority identifier is Q15375062. None of the 0 selected statements returned an explicit reference.

Critical limits

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.

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.
