Nonias

Nonias is a genus of flowering plants in the family Asteraceae. The genus was first described in 1792. Plants in this genus are typically found in South America, with a concentration in Brazil. They are herbaceous annuals or perennials. Nonias species are characterized by their daisy-like flower heads, which usually have ray florets that are yellow or orange and disc florets that are also yellow. The leaves are often simple and arranged alternately along the stem.

The exact number of species within the genus Nonias is subject to taxonomic revision, but it generally includes several distinct taxa. These plants often grow in open, disturbed habitats such as grasslands, savannas, and roadsides. Their ecological role is primarily as a food source for pollinators and as a component of the local flora. While not widely cultivated, some Nonias species may be of local horticultural interest due to their bright, cheerful flowers. Research into the genus Nonias often focuses on its phylogenetic relationships within the Asteraceae family and its biogeography. Further studies may also explore potential medicinal or economic uses, though these are not widely documented.
