Guar
legum
The guar (from Hindi: ग्वार: gvār) or cluster bean, with the botanical name Cyamopsis tetragonoloba, is an annual legume and the source of guar gum. It is also known as gavar, gawar, or guvar bean.
The genus name Cyamopsis means bean-like (from Greek: κύαμος, romanized: kýamos: "bean" + Greek: ὄψις, romanized: ópsis: "view"). The specific name is from Greek: τετράγωνον, romanized: tetrágōnon and Latin: lobus (itself being a loanword of Ancient Greek λοβός) meaning four-squared-lobed.
The origin of Cyamopsis tetragonoloba is unknown, since it has never been found in the wild. It is assumed to have developed from the African species Cyamopsis senegalensis. It was further domesticated in South Asia, where it has been cultivated for centuries.
Guar is drought-tolerant and grows well in semiarid areas.
This legume is a valuable plant in a crop rotation cycle, as it lives in symbiosis with nitrogen-fixing bacteria.
Agriculturists in semi-arid regions of Rajasthan follow crop-rotation and use guar to replenish the soil with essential fertilizers and nitrogen fixation, before the next crop.
Begin with the source’s own compact description: “Guar” is legum. The dossier treats that line as a proposition to test through Guar and legum, not as a finished interpretation.
Why this record matters
The phrase “legum” 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.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Aug 12, 2026. The linked authority identifier is Q264770. The Library of Congress control number is sh85057593. 1 of 1 selected statements include explicit references; 1 carry qualifiers and 0 use preferred rank.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. 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.
