The main objective of the research is to identify the microscopic characters of the starch granuleof the species Phaseolus vulgaris “bean” and Phaseolus lunatus “pallar” (Fabaceae), such as theshape, the hilum, the laminate, the fissure and the extinction cross. Eight seed samples were used,eight varieties of beans, such as caballero, canario, black bean, garbancillo, ñuña type 1, ñuña type 2,ñuña vaquita and panamito; in the same way two pallar, such as large pallar and baby pallar, whichwere acquired in a local market. In each sample, one hundred starch grains were observed, and itwas possible to establish that the starch grains in both species share microscopic characteristics,such as oval, reniform and elliptical shapes; the longitudinal centric fissure with lateral branchesand the extinction cross with curved, straight and wavy arms. However, it was not possible toclea...

This article presents the results of the study of plant microrests (starch grains, plant tissues and silicophytites) registered in dental tartar from two chancay mummies belonging to the Museum of Natural and Cultural History of the Private University Antenor Orrego, in the city of Trujillo, north coast of Peru. Research problems are associated with identifying which vegetables were consumed by the two chancay mummies and understanding the social implications of the use of these plants. The methodology for the analysis of the starch grains was the disaggregation of the dental calculus and the removal of organic matter, with the aim of isolating the micro-remains to be analyzed according to their morphology and taxonomically identifying them. It was established that the two individuals consumed nine species of vegetables and that they placed cotton fiber inside their mouths when they were...
