Sinclairia

Sinclairia is a genus of flowering plants in the family Asteraceae, commonly known as the daisy or sunflower family. These plants are native to Mexico and Central America. The genus was established by Per Axel Rydberg in 1923.

Species within the Sinclairia genus are typically herbaceous perennial plants, though some may be shrubby. They are characterized by their alternate leaves, which are often toothed or lobed. The flower heads are usually composite, bearing ray florets and disc florets, and are often borne in clusters. The exact number of species in Sinclairia is subject to ongoing taxonomic research, but it is estimated to be around a dozen.

Commonly found in arid or semi-arid regions, Sinclairia species often grow in rocky or sandy soils. Their ecological role includes providing nectar and pollen for pollinators. Some species have been traditionally used in folk medicine in their native regions. Further research into the phytochemical properties and ecological interactions of Sinclairia species continues.
