Plucheas

Plucheas are a genus of flowering plants in the family Asteraceae. They are commonly known as ragweeds, though this name is also used for plants in the genus Ambrosia. Plucheas are native to tropical and subtropical regions worldwide, with a significant presence in the Americas, Africa, and Asia. The genus contains a number of species, each with distinct characteristics and distributions.

These plants are typically herbaceous or subshrubs, often found in disturbed habitats, grasslands, and wetlands. Their leaves are usually arranged alternately, and their shapes can vary from ovate to lanceolate. The flowers of Plucheas are small and numerous, typically grouped into heads that form larger, more conspicuous inflorescences. The color of the flowers can range from white and pink to purple, depending on the species. Plucheas are wind-pollinated and produce small, achene fruits.

Some species of Plucheas have been used in traditional medicine for various ailments. For example, certain species are reported to have anti-inflammatory or wound-healing properties. However, scientific research into these medicinal uses is ongoing and varies in scope and conclusiveness. In some regions, certain Pluchea species can be considered weeds due to their rapid growth and ability to colonize disturbed areas. Their ecological role often involves providing habitat for insects and other small animals.
