Abstract Pluchea microcephala (“cuatrocantos”, “lucera”) is a perennial native species from northern Argentina, Bolivia and NW of Perú, commonly used to treat digestive and hepatic disorders in humans. It grows in humid and saline soils, and bordering watercourses. Morphoanatomical characteristics of leaves, stems and capitula have been studied in order to determine the main diagnostic characters for the identification of this species. Light microscope observations were carried out on herbarium specimens, dissociated material, and serial transverse sections of restored herbarium material. Leaves are decurrent, anfistomatic, with eglandulate septate-flagellate trichomes and glandular trichomes with a entire biseriate stem. The mesophyll is isobilateral… More >
