Pollendina

Pollendina is a genus of plants in the family Asteraceae. The genus is native to Australia. Members of this genus are commonly known as button daisies or billy buttons. They are herbaceous perennials that typically grow in arid and semi-arid regions. The plants are characterized by their distinctive button-shaped flower heads, which are usually yellow and rayless. The leaves are often basal and can be simple or divided. Pollendina species are well-adapted to dry conditions and can survive in nutrient-poor soils. They play a role in their native ecosystems, providing habitat and food for insects. The genus was first described in 1836. There are several recognized species within the genus Pollendina, with variations in size, leaf structure, and habitat preference. They are generally low-growing plants, forming clumps or mats of foliage. The solitary flower heads emerge on upright stems. Pollination is typically carried out by insects. The genus is of interest to botanists for its evolutionary adaptations to Australian environments. While not widely cultivated, some species may be found in specialist native plant gardens.
