Lathyrus sativus
species of plant

Lathyrus sativus, also known as grass pea, peagrass, cicerchia, blue sweet pea, chickling pea, chickling vetch, Indian pea, white pea and white vetch, is a legume (family Fabaceae) commonly grown for human consumption and livestock feed in Asia and East Africa. It is a particularly important crop in areas that are prone to drought and famine, and is thought of as an 'insurance crop' as it produces reliable yields when all other crops fail. The seeds contain a neurotoxin that causes lathyrism, a neurodegenerative disease, if eaten as a primary protein source for a prolonged period.
Cultivation
Although the exact origins of L. sativus are debated, it was most likely domesticated in the Balkan region in about 6000 BCE.
Lathyrus sativus grows best where the average temperature is 10–25 °C and average rainfall is 400–650 mm (16–26 in) per year. Like other legumes, it improves the nitrogen content of soil. The crop can survive drought or flooding, but grows best in moist soils. It tolerates a range of soil types from light sandy through loamy to heavy clay, and acid, neutral, or alkaline soils. It does not tolerate shade.

Uses

Begin with the source’s own compact description: “Lathyrus sativus” is species of plant. The dossier treats that line as a proposition to test through Lathyrus, sativus and species, not as a finished interpretation.
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.
Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated Sep 10, 2026. The linked authority identifier is Q162093. None of the 0 selected statements returned an explicit reference.
Current terminology should not be projected backward without checking the classification used when the underlying evidence was created. 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.
