Diphysa americana flowers

Names and taxon limits

Kew accepts Diphysa americana (Mill.) M.Sousa in Fabaceae and lists Diphysa robinioides as a heterotypic synonym. A 2001 Honduras table is text-extracted with the similar spelling “Diphysa robiniodes,” but no voucher or accession was located. The resemblance is not enough to confirm that row as D. americana. “Chipilín” is also used for Crotalaria longirostrata in a separate Honduran university proposal, so the common name alone cannot establish identity.

Honduras Lenca table and Oaxaca food record

The Lenca report table records “Chipilín / Diphysa robiniodes / leaf / wild” for work associated with Goascotoro, Yamaranguila and Quebrada Honda in Intibucá. It does not separate that Diphysa row by community or assign a language to the name. The row’s printed locator is page 62; its image and author title-page details were not verified in this review, and the species crosswalk remains provisional.

A distinct Oaxaca flower account

A 2020 study of the Zaachila and Zimatlán markets names D. americana and records Guachepil and other market-specific forms. Its Table 1 row is coded A, which the legend defines as flowers; it does not code leaves. The authors describe flowers collected and sold from December to April and used especially in Holy Week dishes. Table 4 records forest and home-garden habitat and tolerated/wild management in Oaxaca. These are regional flower observations, not confirmation of the Honduran leaf row or its season.

Reported food contexts

The Oaxaca table codes D. americana flowers in contexts cooked with black beans, used in sauces, and covered with egg. These are food-use categories, not complete recipes with quantities, ordered steps, yield, cooking endpoint or storage instructions. The Honduran table gives no preparation method for its provisional leaf entry. No method is inferred between the regions or plant parts.

Growing and forestry observations

A Honduras Quesungual landscape study lists D. americana among common trees and shrubs and associates it with timber and mulch. Its Candelaria, Lempira study landscape is described at about 490–830 metres, 1,200–1,400 mm annual rainfall, 17–25 °C and shallow acidic soils below pH 5.1. These multi-land-use site values are not measured Diphysa crop requirements.

A separate 2003 Honduran forest report lists Diphysa robinioides or guachipilín in a timber context. That forestry record does not confirm the unvouchered Lenca food row.

Separate Guatemala forestry seed guidance

A 2021 Guatemala forest-seed guide gives a species-specific forestry account: fruit and seed collection around April–May with timing varying by climate and provenance, fresh seed preferred, no pretreatment reported, and mean germination reported near 80%. It includes nursery and seed-storage information. This is positive Guatemala forestry evidence, not Honduran edible-leaf production or a household growing protocol.

Limits and unresolved evidence

No voucher-confirmed Honduras food specimen, Honduras edible-crop trial, Diphysa-specific container or greenhouse method, or local food harvest schedule was established. The Honduras and Oaxaca sources report different parts and remain separate. The forestry data do not establish a food process; none of the inspected food accounts gives a validated safety endpoint or storage duration.

Research gaps

The Honduras Lenca row image, voucher/accession and exact accepted-taxon crosswalk remain unresolved; the current PDF fetch failed.

No language or community-specific Diphysa food attribution is established by the Lenca table.

The Oaxaca evidence concerns flowers only; no inference to the Honduras leaf row is justified.

The Guatemala forestry PDF could not be reopened in this pass; prior full inspection is retained in the dossier, but this article uses only bounded summary facts.

No Honduras food-crop growing protocol, soil response, irrigation, frost/heat tolerance, container or greenhouse evidence was established.

No complete recipe, validated food-safety process, serving amount or storage duration is available.

Research status

The underlying plant account received a partial source review. Its review scope is described in the original plant article.
