Anonychium
genus of flowering plants
Anonychium is a genus of plant in the pea family (Fabaceae). It includes a single species, Anonychium africanum, a tree native to northern Sub-saharan Africa from Mauritania to Uganda and to Saudi Arabia. It is known by the synonym Prosopis africana, and its common names include African mesquite, iron tree, gele, gueni (in Malinke), okpehe, and somb tree. Okpehe is the name given by the Idoma and Igala people of Nigeria to both the tree and its fermented seeds. All of the other derivatives such as okpeye and okpiye stem from the noun okpehe used by the Idoma and Igala people of present day Benue State of Nigeria.
In the Serer creation myth, it is one of the sacred trees that grew not just first, but also within the primordial swamp on Earth.
Logs harvested from mature trees are one of the hardwoods used in crafting the shells of traditional djembes. Seeds of P. africana are used in Nigeria to prepare daddawa, kpaye, and okpeye, which are fermented products used as food condiments.
Several species of bacteria especially Bacillus subtilis, Bacillus licheniformis, Bacillus megaterium, Staphylococcus epidermidis and Micrococcus spp. were found to be the most actively involved organisms in the production of okpiye.
Begin with the source’s own compact description: “Anonychium” is genus of flowering plants. The dossier treats that line as a proposition to test through Anonychium, genus and flowering, not as a finished interpretation.
Why this record matters
The phrase “genus of flowering 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.
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 Mar 18, 2026. The linked authority identifier is Q121364129. 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 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.
