Taraxacum is a genus of flowering plants in the family Asteraceae which consists of species commonly known as dandelions. The scientific and hobby study of the genus is known as taraxacology. The genus has a near-cosmopolitan distribution, absent only from tropical and polar areas. Two of the most common species worldwide, T. officinale (the common dandelion) and T. erythrospermum (the red-seeded dandelion), are European species introduced into North America, where they are non-native. Dandelions thrive in temperate regions and can be found in yards, gardens, sides of roads, among crops, and

Taraxacum officinale, the dandelion or common dandelion, is a herbaceous perennial flowering plant in the daisy family, Asteraceae. The common dandelion is well-known for its yellow flower heads that turn into round balls of many silver-tufted fruit, which disperse in the wind. These balls are sometimes called "clocks" or "blowballs". Originally native to Eurasia, as a result of its hardiness and easy propagation, the dandelion has become widely established across several continents. It has been introduced to southern Africa, the Americas, Australia, and New Zealand. It grows in temperate

Its members are known by various names, including thunbergias and clockvine. Thunbergia on its own usually refers to Thunbergia grandiflora, while Thunbergia alata is often known as black-eyed Susan vine or just

Forstera is a genus of small perennial plants in the Stylidiaceae family named in honour of the German naturalists Johann Reinhold Forster and his son, Georg Forster, who had previously described Forstera's sister genus, Phyllachne just five years earlier. It comprises five species that are endemic to New Zealand with the exception of F. bellidifolia, which is endemic to Tasmania. The species in this genus resemble those in a subgenus of the related genus Stylidium called Forsteropsis, but they are more closely related to the genus Phyllachne. Proposals to merge the two genera based on

Ixia campanulata is a perennial flowering plant and geophyte belonging to the genus Ixia and is part of the fynbos and renosterveld.
