Streptocarpus ( Streptocarpus ), also Germanized Streptokarpus called, is a genus in the family of Gesneriad (Gesneriaceae). Their home of around 135 species is mainly in the forests of tropical and southern South Africa and Madagascar . Many varieties are used as indoor plants .
Names
This plant genus got its common German name Drehfrucht as well as the botanical name Streptocarpus due to the long, spirally twisted fruits that are formed by most species. The botanical genus name Streptocarpus is derived from the Greek words: στρεπτός, streptos for turned and καρπός, karpos for fruit.
description
Appearance
Streptocarpus species are annual to perennial , i.e. monocarpic hapaxanthic plants or mostly perennial , i.e. pollakanthic, polycarpic plants. They grow as evergreen, herbaceous plants that rarely lignify at their base. The greater part of the species is acaulescent, which means that the stem axis is compressed. Some species develop more or less long stem axes that are independently upright, creeping to overhanging.
Foliage leaves
The leaves of most species are arranged in basal rosettes. Exceptions are some species that only form a single large leaf that grows lifelong through a basal meristem, such as Streptocarpus wendlandii and Streptocarpus dunnii . In the species of the Streptocarpella subgenus , the leaves are distributed in opposite directions along the stems; Streptocarpus saxorum is one of them . The mostly finely haired and easily breaking leaves are more or less long stalked and mostly sessile in the subgenus Streptocarpella . The simple leaf blades are in the subgenus Streptocarpus usually elongated and at the subgenus Streptocarpella most nearly circular, rarely obovate to elliptical.
Inflorescences and flowers
On lateral long inflorescence shafts, the flowers are rarely single, usually a few to many in zymous inflorescences .
The individual flowers last a day to several weeks depending on the species. The hermaphrodite, zygomorphic flowers are five-fold with a double flower envelope . The five sepals are usually free or at most fused at their base. The five petals are fused together and the corolla tube ends with two lips. The colors of the petals range from blue to purple and pink to red and white. Of the two pairs of stamens , only one is fertile , the other pair reduced to staminodes usually lacks a staminode. The stamens are often thickened in the middle. The nectaries are ring-shaped or briefly cup-shaped. Two carpels are an ovoid to cylindrical, under constant, mostly single-chamber ovary grown. The scar varies depending on the species.
Fruits and seeds
The capsule fruits , which are more or less cylindrical and spiral during development , open with a slit when ripe, and the spiral opens when they are old. Then they pop up in four flaps and contain a lot of seeds. The very fine (tiny) seeds have a reticulate or warty surface. One gram of seed contains around 40,000 to 80,000 grain.
use
Varieties of some rotary fruit species and hybrids are used as indoor plants .
The main flowering time of the varieties extends from February to October, the individual flowers last one to several days depending on the variety. The flower colors of the varieties range from blue to purple and pink to red and white. There are also varieties with multicolored flowers.
Care in the room
The varieties of twist fruit, according to their tropical origin, like it warm all year round without direct sun and like to have high humidity. When watering, care should be taken to water only on the soil, but not on or between the leaves, as this can lead to rot. With moderate watering, the twist fruit blooms long and intensely. The twist fruit is a light germ . Usually, however, it is propagated by leaf cuttings.
Systematics
The genus Streptocarpus was in 1828 by John Lindley in Botanical Register… , 14 - Appendix to the first… A Sketch of the Vegetation of the Swan River Colony. ... , table 1173 put up. The type species is Streptocarpus rexii (Bowie ex Hook.) Lindl. There is a homonym Streptocarpus Poech , which is a synonym of Encalypta Hedw. is in the moss family Encalyptaceae .
The genus Streptocarpus belongs to the Didymocarpoid Gesneriaceae within the Gesneriaceae family . For some authors, the species of the genus Saintpaulia are also incorporated into the genus Streptocarpus . The four Asiatic species probably belong to different genera with twisted fruits. The genus Streptocarpus is divided into the two sub-genera Streptocarpus (2n = mostly 32 and multiples thereof: 64, 96, 128) and Streptocarpella Engl. (2n = mostly 30).

Research object
The genus Streptocarpus has long been a research object in which various aspects of botany such as the phylogeny and ontogeny of different species are investigated with the help of biochemical and molecular biological methods. Dieter Heß discovered mRNA in 1961 as a trigger for the induction of blooming in Streptocarpus wendlandii .
