Source-derived summary

Dryopteris crassirhizoma is a fern species in the wood fern family Dryopteridaceae.

This semi-evergreen fern grows to 1 m (3.3 ft) tall and broad, with narrowly divided fronds growing in a vase-like shape from a central crown, which is brown in colour.

It has gained the Royal Horticultural Society's Award of Garden Merit.

The acylphloroglucinols (flavaspidic acids) isolated from D. crassirhizoma show in vitro antibacterial and fatty acid synthase inhibitory activity. Also, the constituents sutchuenoside A and kaempferitrin have in vivo antiparasitic activity.

Editorial summary

The public source identifies “Dryopteris crassirhizoma” as species of plant. This brief keeps that definition visible, then builds a research path around Dryopteris, crassirhizoma and species.

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 83-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 value is orientation rather than verdict, with Dryopteris, crassirhizoma and species providing the first useful test.
Editorial analysis

Why this record matters

A short description can identify a subject without explaining its stakes. For “Dryopteris crassirhizoma”, the useful work is to connect “species of plant” to the records capable of establishing context and consequence.

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 Aug 10, 2025. The linked authority identifier is Q2043064.

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.
