Inflorescences of Restio tetraphyllus

The Restionaceae are a plant family in the order of Süßgrasartigen ( Poales ). Some species are used as ornamental plants in the tropical belt in parks and gardens. As an extinct applies Elegia fastigiata mast., An endemic species of the Cape flora ( South Africa). The oldest pollen finds of the family come from the Upper Cretaceous.


They have a distribution in the southern hemisphere. In South Africa and Australia take the Restionaceae in the natural vegetation, the ecological niches of the grasses ( Poaceae ), Rushes ( Juncaceae ) and sedge family ( Cyperaceae ) a. After colonization by the Europeans were aware of these plant groups (for example, to create grazing land ) or unintentionally partially displaced. The original home of the taxa of the Restionaceae are the tropical and subtropical areas, or rarely the hot temperate areas in southern Africa, Madagascar, Australia, Tasmania, New Zealand, Southeast Asia, New Guinea, and southern South America. The area is disjointed and largely corresponds to the supercontinent of Gondwana.


There are perennial herbaceous plants with grass-like growth; some species are evergreen. They usually form rhizomes. Some species are Xeromorph. Photosynthesis is often carried out by the stems as the leaves are often greatly reduced. The stalks are often in the shape of nodes and internodes divided (as in the grasses ). The leaves are alternate.

Most taxa are dioecious getrenntgeschlechtig ( dioecious ), rarely monoecious. The male and female inflorescences often look different. The small, mostly unisexual, rarely hermaphrodite flowers are triple and radial symmetry to slightly zygomorphic. There are one or usually two circles with each bloom cladding, three or six. Per flower, one, or two or three stamens be present. In the female flowers sometimes staminodes are present. Per female or hermaphrodite flower, there are usually three or more rarely a carpel / leaves.

Are formed capsule fruits or nuts.

The fruits of many species germinate usually made only after a bushfire, the actual trigger (smoke or ash) is not known. The germination rate is despite appropriate environmental conditions often rather low, so that a breeding partially proves to be difficult.
