aceris

Aceris is a genus of flowering plants in the family Asteraceae, native to the Mediterranean region and parts of Asia. The genus includes about 20 species of annual and perennial herbs, known for their daisy-like flowers and fern-like leaves. The most well-known species is Aceris paludosa, commonly called marsh thistle or marsh fleabane, which is often found in wetland habitats.

The genus Aceris is characterized by its alternate, pinnate leaves, which are deeply divided into many small segments. The flowers are typically yellow or white, with a central disc surrounded by ray florets. The fruit is an achene, a dry, one-seeded fruit with a pappus of bristles.

Aceris species are often used in horticulture and landscaping due to their attractive flowers and ability to thrive in various soil conditions. They are also used in traditional medicine in some cultures, where the leaves and flowers are employed for their potential healing properties.

The genus Aceris is of particular interest to botanists and ecologists due to its ecological niche in wetland environments. The plants help to stabilize soil and prevent erosion, and their flowers provide nectar for pollinators. However, some species can be invasive in certain regions, where they may outcompete native flora.
