This collection is part of a series of community-based floristic and ethnobotanical studies that form part of a project directed by Jonathan D. Amith. Two teams of two botanists each collected monthly (approx. 8 days/month) in: (1) San Juan Tahitic, municipality Zacapoaxtla, (2) Zongozotla, munic. Zongozotla,(3) Atlequizayán, munic. Atlequizayán, (4) Rosa de Castilla, munic. Zautla; (5) Cuauhtémoc, munic. Ayotoxco, (6) Yoloctzin and Paso Real, municipalities Tlatlauquitepec y Yaonahuac, respectively. The leaders of the two teams were Canek Ledesma Corral (1–3) and Miriam Jímenez Chimil (4–6) and included two Nahuat-speaking biologists: Mariano Gorostiza Salazar (S. Mig.Tzinacapan) and Anastasio Sotero Hernández (S. Juan Tahitic) who in addition to their responsibilities for collection, photography, and maintaining field notes contributed their knowledge of Indigenous nomenclature, classification, and use of plants. In year 2, Osbel López Francisco, a Totonac speaker and biologist from Zongozotla, joined the project.

Status of documentation:Material from Tlaquimpa and Tepetzintla (Nahuatl-speaking) and Tonalixco (Totonac speaking) was gathered in two collection trips to date. The first was carried out by Jonathan D. Amith and Ceferino Salgado; the second was carried out by Ceferino Salgado and Osbel López Francisco. The major Nahuat-speaking consultants were Pablo Ruiz González and José Benito Ruíz Pavón (Tlaquimpa); Concepción Robles Fernández and Josefa Fernández (Tepetzintla); and Miguel Juan López Bonilla, Nicolasa Gómez Hernández, and Agustina María Pacheco Cruz (Tonalixco). The results include 242 collections and 779 in situ photographs.

Funding support: Generous support for floristic and ethnobotanical research was provided by the National Science Foundation, Documenting Endangered Languages; National Endowment for the Humanities, Preservation and Access; and the Comisión Nacional para el Conocimiento y Uso de la Biodiversidad (Mexico).
