Source-derived summary

Lactuca indica, Indian lettuce, is a species of plant in the tribe Cichorieae within the family Asteraceae. It is native to western China (Xinjiang, Tibet), the Himalayas, and southwest Asia, as far west as Turkey. It is widely introduced elsewhere, even as far as east Africa, and is thought to be an archaeophyte in Japan, brought in with rice cultivation.

Lactuca indica is a biennial herb, growing from a taproot to at least 40 cm tall and often reaching 2 m. Its flowers have white to pale yellow ray florets with yellower centers. The narrowness of the leaf blades and the degree of spikiness of leaf lobes varies greatly by region.

It is cultivated (or rather, its growth is encouraged) as fodder for rabbits, pigs, poultry and even fish in Asia. Its young leaves can be, and are, consumed as a leaf vegetable in salads like other dandelions. It is also used in traditional medicines as an aid to digestion.

Editorial summary

This brief starts where responsible research should: with the source description of “Lactuca indica” as species of plant. Everything that follows is an evidence route, not borrowed authority.

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 160-word lead offers orientation but no explicit four-digit date, so chronology should not be assumed. The selected authority fields contribute no independent date. The account is most persuasive where Lactuca, indica and species can be independently traced.
Editorial analysis

Why this record matters

The subject matters to the science & nature register because the source frames it as species of plant. Its deeper value depends on whether names, dates, institutions and citations support that framing.

Evidence profile

Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated Feb 17, 2026. The linked authority identifier is Q4236769. None of the 0 selected statements returned an explicit reference.

Critical limits

Current terminology should not be projected backward without checking the classification used when the underlying evidence was created. 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.
