Chrysocoma

Chrysocoma is a genus of flowering plants in the family Asteraceae, commonly known as golden buttons or goldentops. These plants are native to Africa, with a particular diversity found in the Cape Provinces of South Africa. They are characterized by their bright yellow, button-like flower heads, which are typically arranged in corymbs or panicles. The leaves are usually small and can be linear, lanceolate, or spatulate, and are often aromatic.

The genus Chrysocoma contains a number of species, though taxonomic classifications can vary. Some well-known species include Chrysocoma ciliata, Chrysocoma coma-aureum, and Chrysocoma tenuifolia. These species are often found in arid or semi-arid environments, growing in sandy soils, rocky slopes, and disturbed areas. They are well-adapted to drought conditions.

Economically and culturally, some species of Chrysocoma have been used in traditional medicine for various ailments, although scientific validation for these uses is often limited. The bright flowers can also make them attractive as ornamental plants in suitable climates, though they are not widely cultivated. The genus name itself, Chrysocoma, is derived from Greek words meaning "golden hair," referring to the appearance of the flower heads.
