This collection is part of a series of community-based floristic and ethnobotanical studies carried out as part of a project directed by Jonathan D. Amith. Two teams of two botanists each collected monthly (approx. 8 days/month) in the following communities: (1) San Juan Tahitic, municipality Zacapoaxtla, (2) Zongozotla, municipality Zongozotla,(3) Atlequizayán, municipality Atlequizayán, (4) Rosa de Castilla, municipality Zautla; (5) Cuauhtémoc, municipality 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). In addition, Ledesma was director in charge of organizing the two teams, overseeing the goal attainment, including the administration of the collections database and organizing the in situ photographs. The teams included two Nahuat-speaking biologists: Mariano Gorostiza Salazar (San Miguel Tzinacapan) and Anastasio Sotero Hernández (San 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: The team for the S. J. Tahitic project was Canek Ledesma and Anastacio Sotero. The major Nahuat-speaking consultants were Manuel Calpotitan and Magdaleno Lorenzo. The results include 1,433 collections and just under 4,000 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; the Endangered Language Documentation Programme (School of Oriental and African Studies, London); and the Comisión Nacional para el Conocimiento y Uso de la Biodiversidad (Mexico).
