Alache greens (Anoda cristata)

Name and botanical scope

Kew accepts Anoda cristata (L.) Schltdl. in Malvaceae. A Veracruz cookbook entry links alache, alachi and pax’tamac, among other names, to its account of this plant. These names are evidence for the places and text that use them; they do not identify an unvouchered plant in another setting.

Food accounts from Veracruz

The cookbook records distinct regional dishes: a Totonacapan soup called sopa de pax’tamac that uses flowers and leaves, a Grandes Montañas entry for tacos made with alache flowers, and a separate Totonacapan flower-and-egg dish served with pipián. The flower-taco entry is associated with Nahua communities of Zongolica and Coscomatepec. These are source-reported food traditions, not validated instructions for identifying or preparing an unknown plant.

Place and season

The Veracruz account says the plant grows in some humid ravines, is gathered when flowering, and flowers nearly all year in that local description. A 2001 abstract separately reports rainy-season food use in fields near Santiago Mamalhuazuca, State of Mexico. These observations belong to their respective places and do not form a national harvest calendar.

Growing observations in Guerrero

A common-garden study in La Montaña, Guerrero, distinguishes plants sown in small beds, volunteers tolerated among maize, and spontaneous plants in disturbed places. It reports a research nursery sequence and later outdoor transplanting; this documents experimental propagation and local management categories, not a household growing prescription.

The study setting is not a tolerance range

The Guerrero study describes its locality at about 1,300 m, with warm subhumid summer-rain climate and source-cited precipitation of 700–1,500 mm and temperature of 18–26°C. The figures describe the study setting, not temperature or rainfall limits for this species. The paper reports nursery use of prepared soil and shade mesh, every-third-day watering, and transplanting after true leaves developed during the rainy season. It does not establish mature container production, a greenhouse crop, soil pH, or garden yield.

Food and laboratory limits

A 1989 UNAM thesis analyzed dried, ground leaves, tender stems and flowers from Alcozauca. It reports qualitative alkaloid-test reactivity and says fresh or steamed preparation effects needed further study. The screening does not identify a particular toxin, quantify human exposure, or validate a safe amount or cooking endpoint. These older tests should not be read as either proof of safety or proof of toxicity.

What remains unresolved

The inspected sources do not provide a voucher-backed field-identification guide, a validated food-safety endpoint, storage guidance, mature pot-growing conditions, or a species-wide frost or heat limit. The regional recipe entries are not combined into one method.

Research gaps

No voucher-matched field identification source or diagnostic key was established.

The recipe entries report traditional batches but do not validate plant identity, food safety, storage or a hazard-control endpoint.

The 1989 thesis screening does not identify a specific toxin or establish human risk; fresh/steamed preparation effects remain unresolved.

The Guerrero study is an experimental/local context; no species-wide climate tolerance, soil pH, mature container crop, greenhouse food production, yield or regrowth guidance was established.

The State of Mexico source was inspected only as article metadata and bilingual abstracts.

Research status

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