Tagetes microglossa is a species of annual flowering plant in the genus Tagetes, which belongs to the sunflower family, Asteraceae. It is primarily native to the Andean regions of South America, with its distribution spanning countries such as Ecuador, Peru, Bolivia, and northern Argentina.
Taxonomy and Etymology
The species was formally described by the English botanist George Bentham. The specific epithet, microglossa, is derived from the Greek words mikros (small) and glossa (tongue). This name refers to the characteristic small size of the ray florets (the "tongues" of the flower head) compared to other members of the genus.
Description
Tagetes microglossa is an herbaceous annual plant. Like many other members of the Tagetes genus, it is known for possessing secretory glands that produce a distinct aromatic scent. The plant typically features pinnate leaves and small, terminal flower heads. The inflorescences are composed of disc florets and a limited number of inconspicuous ray florets, which are generally yellow or pale yellow in color.
Distribution and Habitat
The species is typically found in mid-to-high altitude environments within the Andes. It often grows in disturbed soils, along roadsides, or in open scrublands and agricultural fields. Its ability to thrive in varied mountain climates allows it to occupy a wide range of elevations within its native territory.
Ethnobotanical Uses
In various Andean cultures, Tagetes microglossa is utilized for its aromatic and medicinal properties. It is frequently employed in traditional medicine as an infusion to treat digestive disorders, such as stomach aches and indigestion. Additionally, it is sometimes used as a culinary herb or flavoring agent, serving a purpose similar to that of the more widely known Tagetes minuta (huacatay), though it is generally less commercially prominent.
Chemical Composition
Phytochemical studies of the genus Tagetes suggest that T. microglossa contains various essential oils and secondary metabolites, including thiophenes and flavonoids. These compounds are associated with the plant’s characteristic odor and its observed antimicrobial or insecticidal properties, though specific research dedicated solely to the chemical profile of T. microglossa is less extensive than that of other marigold species.
