Erolla

Erolla is a genus of flowering plants in the family Asteraceae, commonly known as the daisy family. The plants in this genus are native to the Mediterranean region and parts of western Asia. Erolla species are typically herbaceous perennials, though some may be annuals or subshrubs. They are characterized by their daisy-like flower heads, which usually have white or pale pink ray florets surrounding a yellow or greenish-yellow center composed of disc florets. The leaves are generally lance-shaped or ovate and can be entire or toothed.

The genus Erolla is relatively small, with only a few recognized species. These species often exhibit adaptations to dry or arid environments, such as small, often hairy leaves that help reduce water loss. The flowers are typically produced in summer and attract various pollinators, including bees and butterflies. The fruits are achenes, a type of dry, indehiscent fruit, which are dispersed by wind or animals.

Historically, some species within Erolla have been used in traditional medicine for various ailments, though scientific evidence supporting these uses is often limited. Cultivation of Erolla species is not widespread, and they are not commonly found in horticulture. Their primary ecological role is as a component of Mediterranean and steppe vegetation, contributing to biodiversity in these ecosystems. The genus's taxonomy has seen some revisions over time, with certain species sometimes being classified under other related genera within the Asteraceae family.
