Some species are cultivated ornamental plants for parks and gardens, as an annual summer flowers. Some species are " cropping trees " in high mountain regions in Africa, they belong to the subgenus Tupa.
The genus is distributed worldwide; the home ranges of most species are tropical or subtropical. One focus of the biodiversity of the genus are found in the Neotropics. Centers of diversity are the African continent and Mexico. 69 species are native to South Africa.
There are one to perennial herbaceous plants; at the " Schopf tree" species of woody stem. Most parts of the plants are hairless, except for example, the " crested tree" species. It is usually formed a significant main root. The plants carry a clear or milky white. The stems are erect to decumbent and usually only slightly branched. The mostly alternate, sessile leaves are simple. The leaf margins are often serrated, smooth or rarely lobed. Stipules absent.
The flowers appear singly or in racemose, aged men, doldigen or zymösen inflorescences, usually with foliage leaf-like bracts reduced to. The position of the flower comes about through Resupination (even with orchids ) of the hypanthium. The flowers are zygomorphic and fünfzählig. Usually the flowers are hermaphroditic; when the flowers are unisexual then are the types dioecious getrenntgeschlechtig ( dioecious ). The five sepals are fused Roehrig. The five petals are have grown Roehrig; almost to the base split on the top of the corolla tube ends two-lipped with outstretched Corolla lobe. The upper lip consists of two often narrow and erect to recurved Corolla lobe, which are usually much shorter than the lower lip. The lower lip is composed of three outstretched Corolla lobe. There is only one circuit available with five stamens, they are adherent to the base of the petals. The stamens are fused to at least half its length; but they can split apart in some species in Blühverlauf. The anthers are fused into a tube surrounding the style. The anthers often have at their head a tuft of short hairs. The top three anthers are slightly longer and can sometimes be hairless. Two carpels are fused into one inferior ovary. The style ends in a bilobed scar. The carpels form zweiklappig aufplatzende capsule fruits.
The flowers are protandrous. Most species have very bright colored flowers. Many of the native to the Andes Mountains species are pollinated by birds ( hummingbirds ), others of various insects ( bees and butterflies ).
