Cynodon dytahilo
Enable an agent to resolve the identity of Cynodon dytahilo, document attributable plant observations, and judge which identification or management actions the evidence supports.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify.

Purpose and description
Enable an agent to resolve the identity of Cynodon dytahilo, document attributable plant observations, and judge which identification or management actions the evidence supports.
"Cynodon dytahilo" is an unresolved botanical-looking name whose spelling does not permit a confident identification from recall.
It can be Trace Cynodon dytahilo to its originating registry and taxonomic records.; Compare a specimen with a regional Cynodon key and record the determination.; Request flowering material or detailed ligule and spikelet images when identification remains unresolved.; Monitor attributed patches for seasonal condition and vegetative expansion.; Assess whether propagation, retention or containment is justified by confirmed identity and site context.; Link this entry to an existing model if evidence establishes that it represents the same taxon..
Distinguishing features
Check the exact epithet dytahilo against an authoritative taxonomic record; spelling similarity alone cannot establish identity with dactylon.
For the C. dactylon hypothesis, examine both surface stolons and underground rhizomes; a creeping grass habit alone is insufficient.
Compare raceme arrangement, spikelet structure and ligule characters together against a regional botanical key.
Separate species identification from cultivar or hybrid identification; turf appearance does not establish either.
Require a traceable specimen or diagnostic observation before transferring records filed under another Cynodon name.
Scope
+ Provenance and taxonomic interpretation of the exact name Cynodon dytahilo
+ Evidence linking the registry entry to a botanical taxon
+ Diagnostic observations of specimens attributed to the entry
+ Growth, reproduction and patch condition after identification
+ Site-specific decisions supported by confirmed identity and observed condition
- The genus Cynodon as a whole
- An independently established model of Cynodon dactylon unless identity is resolved
- Other Cynodon species, hybrids and named cultivars
- Whole lawns, pastures and their management systems
- Herbicide products, application equipment and treatment protocols
- Medicinal preparations or claims inferred from a similar plant name
Characteristics
- Taxonomic interpretation
- unresolved | accepted-name match | documented synonym | documented misspelling | misapplied name Determines whether observations under Cynodon dytahilo can inherit information from another taxon.
- Identity evidence
- Registry source record, taxonomic authority, determination and voucher links Makes any proposed correction or equivalence auditable.
- Observed spreading structures
- surface stolons | underground rhizomes | both | neither observed | unexamined Supports identification and assessment of vegetative persistence without treating an unexamined structure as absent.
- Inflorescence architecture
- Raceme number and arrangement; flowering material absent or present Provides diagnostic evidence beyond the appearance of a mown grass patch.
- Spikelet length
- mm, with sample count and developmental stage Supports comparison with the diagnostic range in an applicable botanical key.
- Ligule morphology
- Observed membrane, fringe of hairs, combined form or unresolved Adds a leaf-junction character to distinguish superficially similar grasses.
- Patch extent
- m² and observation date Supports repeated assessment of establishment or spread after attribution is confirmed.
- Seasonal condition
- actively growing | flowering | apparently dormant | stressed | dead | unresolved Prevents brown or recently cut material from being classified as dead without supporting evidence.

Drafted structure
Bundle to layer to finding to question, as the second pass will find it: 5 bundles · 9 layers · 10 findings · 18 questions.
Name and taxon resolution Establish what the registry label Cynodon dytahilo denotes before importing species traits.
The entry lacks a definition, and an apparent resemblance to another epithet must not become an unsupported taxonomic correction.
Registry name provenance
Trace the exact spelling and the source concept that supplied it.
Dytahilo source chain
Search surfaced a Wikidata record carrying the exact label; its originating evidence and relationship to this registry entry still require inspection. [Wikidata Q13165530](https://www.wikidata.org/wiki/Q13165530).
- Which source identifier and import record supplied Cynodon dytahilo to vr.tr.cynodon-dytahilo? provenance
- Does the underlying record document a botanical name, transcription error or misapplied label? definition
Candidate taxonomic equivalence
Evaluate possible equivalence without silently renaming the registered thing.
Dactylon equivalence test
Kew accepts Cynodon dactylon (L.) Pers.; that establishes a candidate taxon but does not establish equivalence with dytahilo. [Kew taxon record](https://powo.science.kew.org/taxon/urn%3Alsid%3Aipni.org%3Anames%3A397065-1).
- What authoritative evidence explicitly connects dytahilo with C. dactylon or another accepted taxon? provenance
- If equivalence is established, which existing registry or world-model publication should this entry reference? boundary
Specimen diagnosis Collect botanical characters that can test the proposed Cynodon identity.
A label or turf-like appearance cannot distinguish the intended taxon from related grasses.
Vegetative characters
Examine spreading stems and leaf-junction anatomy.
Stolon, rhizome and ligule comparison
For the C. dactylon hypothesis, Kew's flora accounts describe surface stolons, underground rhizomes and a ciliate membranous ligule; these are comparison characters, not confirmed properties of this entry. [Kew flora accounts](https://powo.science.kew.org/taxon/urn%3Alsid%3Aipni.org%3Anames%3A397065-1/general-information).
- Does attributed material show surface stolons, underground rhizomes and the ligule form required by the selected key? measurement
- Which locally occurring grasses remain plausible matches after examining those characters? boundary
Flowering characters
Use flowering material to strengthen or reject the vegetative identification.
Raceme and spikelet diagnosis
Record raceme arrangement, spikelet dimensions and glume and lemma characters against a named regional key, retaining uncertainty when mowing or immaturity prevents examination.
- What raceme arrangement, spikelet measurements and glume and lemma characters are present on mature material? measurement
- Which diagnostic couplets support or exclude the candidate identification? provenance
Growth and persistence Characterize how an identified occurrence persists, expands and changes seasonally.
Management depends on living spreading structures and reproductive evidence, not merely visible leaf cover.
Vegetative expansion
Distinguish the visible patch from the extent of its living spreading structures.
Patch and propagule boundary
Determine whether attributed shoots are connected and whether detached material can establish; do not assume a patch represents one genetic individual.
- How far do observed living stolons or rhizomes extend beyond the mapped leafy patch? measurement
- What evidence establishes which fragments or reproductive structures can initiate new growth? provenance
Seasonal and reproductive state
Separate active growth, flowering, stress and apparent dormancy.
Viability and regrowth evidence
Use repeated observations of shoots and spreading structures to judge persistence; neither seed fertility nor death should be inferred from appearance alone.
- What dated observations distinguish temporary browning or cutting from loss of viability? measurement
- Has viable seed production been demonstrated for this identified material, rather than assumed from flowering? provenance
Site role and management Connect confirmed identity and observed growth to the purpose and constraints of a particular site.
The same attributed grass patch may be retained or removed depending on site objectives and evidence of spread.
Occurrence and site role
Separate observed presence, intended use and documented regional status.
Attributed occurrence context
Record whether the plant is deliberately established or spontaneous, and attach distribution or introduction claims only to the resolved taxon.
- Is this occurrence planted turf, forage, experimental material or spontaneous vegetation, and what supports that classification? definition
- Which locality-specific source establishes the resolved taxon's native, introduced or otherwise designated status? provenance
Intervention and follow-up
Choose and assess interventions using identification confidence and observed persistence.
Retention or containment decision
Frame retention, propagation or containment around site objectives, surviving growth structures and follow-up evidence; species-specific prescriptions await identity resolution.
- Does confirmed identity and site purpose support retaining, propagating or containing this occurrence? action
- What observations and follow-up interval will reveal regrowth or establishment outside the intended patch? measurement
Evidence and external alignment What the world already says about this thing, gathered so the model can be checked against it.
A model that cannot be lined up against existing standards, identifiers and practice cannot be adopted by anyone who already uses them.
Reported evidence
Findings from the breadth pass, kept separate from the structural claims.
Check these first
Recalled without web access and unsourced; every item is a lead to verify.
- Check the original label and any linked taxon identifier before assigning an identity.
- The name may contain a transcription or spelling error; no species-level characteristics can safely be attributed to it yet.
- Which of these check these first hold for the sense of Cynodon dytahilo this model covers, and on what evidence? provenance
Neighbouring kinds and how to tell them apart
Recalled without web access and unsourced; every item is a lead to verify.
- Cynodon dactylon - Cynodon dactylon is the scientific name of Bermuda grass; it is a possible intended name, but equivalence requires checking the original registry record.
- Which of these neighbouring kinds and how to tell them apart hold for the sense of Cynodon dytahilo this model covers, and on what evidence? provenance
What the second pass must settle
- Is Cynodon dytahilo an independently documented botanical name, an erroneous spelling of Cynodon dactylon, or another kind of label?
- Does the originating registry identifier establish equivalence with a taxon already covered by a Vercy publication?
- Which authoritative regional key and voucher material can establish diagnostic boundaries for the intended taxon?
- Does material attributed to this entry include cultivars, hybrids or misidentified grasses requiring separate identification?
- Which growth, reproductive, distribution and management claims remain valid after the entry's identity is resolved?
