Alydia

Alydia is a genus of flowering plants in the family Asteraceae, commonly known as daisies. The genus was first described in 1906. Alydia species are native to South America, with a distribution that includes Argentina, Bolivia, Brazil, and Paraguay. These plants are typically herbaceous perennials, often found in grasslands and open woodlands.

The flowers of Alydia are characteristic of the daisy family, featuring a central disc composed of many small florets surrounded by ray florets. The color of the ray florets can vary, but is often white or pale yellow. The foliage is usually simple and may be arranged alternately or oppositely along the stem. Alydia plants are generally adapted to temperate or subtropical climates.

While not widely cultivated, some species of Alydia may be found in botanical collections or used in native plant gardening. Their ecological role involves contributing to biodiversity and providing a food source for local fauna. Research into the genus is ongoing, focusing on its phylogenetic relationships within the Asteraceae family and its specific adaptations to its native habitats. The genus Alydia is relatively small, with a limited number of recognized species.
