genus of plants
Calligonum is a genus of plants in the family Polygonaceae with about 41 species native to Northern Africa, Western, South, and Central Asia, and central China.
Description
Plants of the genus Calligonum are shrubs, diffusely but irregularly branched, with flexuous woody branches. Leaves are simple, opposite, nearly sessile, linear or scale-like, sometimes absent or very small, linear or filiform, distinct or united with short membranous ochreae.

Why this record matters
“Calligonum” is worth following because a concise public description often conceals a longer documentary argument. Here, Calligonum, genus and plants provides the most credible route into that argument.
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 Oct 26, 2025. The linked authority identifier is Q2988961. The first chronological checks are 1753.
A general summary may omit uncertainty, sample limits or methodological disagreement that is explicit in the technical record. 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.
