Source-derived summary

Halodule wrightii is an aquatic plant in the Cymodoceaceae family. It is referred to by the common names shoal grass or shoalweed, and is a plant species native to seacoasts of some of the warmer oceans of the world.

H. wrightii is an herb growing in salt-water marshes in intertidal regions, often submerged at high tide but emergent at low tide.

Taxonomy

This plant was named after Charles Wright, who was an American botanist and collector. In 1853 and 1856 Wright participated in a surveying expedition and discovered Halodule wrightii.

Some publications cite US specimens by the synonym, Halodule beaudettei, but the two names represent the same species.

Description

Seagrass is a marine angiosperm that possesses conductive tissue, shoot systems, rhizomes and flowers. It has flat leaves up to 20 cm (7.9 in) long, dark reddish-brown, with a few teeth on the margins. The fruits are spherical to egg-shaped, about 2 mm across.

Distribution

This plant is mainly found in muddy coastal marsh waters and off the coast of many Caribbean islands.

Editorial summary

Begin with the source’s own compact description: “Halodule wrightii” is species of plant. The dossier treats that line as a proposition to test through Halodule, wrightii 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 lead gives the account dated anchors—1853, 1856—that can be checked directly. The selected authority fields contribute no independent date. For this dossier, Halodule, wrightii 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

Stable identifiers, scientific names and standards terminology offer the best bridge between this overview and specialist evidence. The source revision retrieved here is dated Nov 28, 2025. The linked authority identifier is Q5643366. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1853 and 1856.

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.
