Source-derived summary

Eustoma, commonly known as lisianthus or prairie gentian, is a small genus of plants in the gentian family. They are native to warm regions of the southern United States, Mexico, Caribbean and northern South America. This genus is typically found in grasslands and in areas of disturbed ground.

Description

They are herbaceous annuals, growing to 15–60 cm (6–24 in) tall, with bluish green, slightly succulent leaves and large funnel-shaped flowers growing on long straight stems: sometimes erect single stems, other times branching stems. The flowers can grow up to 50 millimetres (2 in) across and can be found in a variety of colors. They have been found in all shades of pink, purple, white, and blue. In addition, some are bicolored and some are occasionally found in yellow or carmine-red.

Eustoma flowers are either single-flowered or double-flowered. Both types of flowers can be found in all ranges of the possible colors listed above. They are usually 30–90 cm (1–3 ft) tall, although there are dwarf varieties that only grow up to 200 mm (8 in) in height.

Editorial summary

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

Editorial reviewA sound reference starting point where classification, measurement and the date of the underlying evidence remain visible. The current 177-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, Eustoma, genus and plants is the immediate research focus.
Editorial analysis

Why this record matters

The phrase “genus of plants” 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 Aug 19, 2025. The linked authority identifier is Q2346291. 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 source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. 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.
