The Mutisioideae are a subfamily of the family of plants of the daisy family (Asteraceae). The distribution is mainly neuweltlich; some species are also found in Africa, Asia and Australia.

Best known are the sorts of gerberas, which are among the most popular cut flowers around the world today; more recently, some varieties are also offered as houseplants.

Description

There are annual to perennial, herbaceous plants or woody plants: subshrubs to shrubs. The usually alternate and spiral, distributed in basal rosettes or on the stem, often against constantly arranged leaves are usually simple. The leaf margin is smooth, dentate to serrate, sometimes prickly.

Only sometimes are dioecious species getrenntgeschlechtig ( dioecious ), usually they are monoecious with hermaphrodite or functionally unisexual flowers. The small to large bloom conditions are usually solitary or rarely many ( hundreds ) in large total inflorescences together. There are only a rare, usually few available to many rows of bracts. Chaff leaves are missing.

The ray florets are female, with double-lip crown; rarely they are missing. In the subfamily of Mutisioideae is the corolla of the ray florets of two Kronlippen; this is also in the subfamily Barnadesioideae so, but is only on Mutisioideae a Kronlippe of three and the other two petals. The disk flowers are hermaphrodite, or functionally male, with fünflappiger crown; they are radial symmetry to zygomorphic, sometimes a Corolla lobe is enlarged. The two stigma lobes are short. There are five stamens present.

The achenes have a pappus.

The subfamily of Mutisioideae was formerly much more extensive and included the genera of the new subfamilies: Barnadesioideae, Gochnatioideae, Hecastocleidoideae, Pertyoideae, Gymnarrhenoideae, Stifftioideae and Wunderlichioideae.

The subfamily of Mutisioideae, the Group today only three tribes with about 44 genera and about 630 species:
