Diarthra

Diarthra is a genus of flowering plants in the family Asteraceae, commonly known as the daisy family. The genus is native to South America, with species found in Argentina, Brazil, Paraguay, and Uruguay. Diarthra species are typically herbaceous perennials, growing from rhizomes or thickened roots. They are characterized by their daisy-like flower heads, which usually have white ray florets and yellow disc florets. The leaves are generally simple and alternate along the stem.

The genus Diarthra was first described by botanist Carl Linnaeus in 1753. It is closely related to other genera within the Asteraceae family, such as Bellis and Erigeron. The exact number of species within Diarthra can vary depending on taxonomic classification, but it typically includes a small number of distinct species. These plants are often found in grasslands, savannas, and open woodlands. Their pollination is usually carried out by insects, attracted to the bright flowers.

While not widely cultivated, some species of Diarthra may be found in botanical gardens or specialized collections. Their ecological role includes providing a food source for pollinators and contributing to the biodiversity of their native habitats. Further research into the genetics and evolutionary history of Diarthra continues to refine our understanding of this genus within the vast Asteraceae family.
