Streptocarpus
Streptocarpus ("twisted fruit" from Greek στρεπτός (streptos) "twisted" and καρπός (karpos) "fruit") is an Afrotropical genus of flowering plants in the family Gesneriaceae. The genus is native to Afromontane biotopes from central, eastern and southern Africa, including Madagascar and the Comoro Islands. The flowers are five-petalled, salverform tubes, almost orchid-like in appearance, and hover or arch over the plant, while the pointed, elongate fruit is of a helical form similar to that of the "tusk" of a narwhal. In the wild, species can be found growing on shaded rocky hillsides or cliffs,

海角櫻草属（学名：Streptocarpus），又名菫蘭属或旋果苣苔属，為苦苣苔科下的雙子葉開花植物。其原生於非洲中部、東部、與南部的山區，亦分佈於馬達加斯加與葛摩群島。此屬共有176種並分為兩個亞屬Streptocarpus與Streptocarpella，其成員包含園藝常見的非洲堇、菫蘭等。在其原生地非洲，這些植物通常生長在有陰影遮蔽的山坡或石壁上。而作為一種常見園藝植物，現在已有許多園藝雜交種的出現。 在型态特徵上，此属植物的花均为五瓣，花冠為高腳碟狀，近似兰花的型态自花序垂挂而下。而其名海角樱草又显示着植物的叶部型态与报春花科的樱草相似（英文俗名：Cape Primrose 即 好望角报春花）。此属原被定义的分类特徵为「具有螺旋型果荚」（属名源自拉丁文strepto = 旋型，carpus = 果实），但后来发现此特徵广泛分佈于其他旧世界的苦苣苔科物种上。 DNA分子親緣關係研究显示，虽然不具有螺旋型的果荚，但园艺植物非洲堇可能演化自坦尚尼亚的Streptocarpella亚属，而主張將非洲堇屬降級為Streptocarpella亞屬的一個組──非洲堇組（sect. Saintpaulia）。

Streptocarpus ("twisted fruit" from Greek στρεπτός (streptos) "twisted" and καρπός (karpos) "fruit") is an Afrotropical genus of flowering plants in the family Gesneriaceae. The genus is native to Afromontane biotopes from central, eastern and southern Africa, including Madagascar and the Comoro Islands. The flowers are five-petalled, salverform tubes, almost orchid-like in appearance, and hover or arch over the plant, while the pointed, elongate fruit is of a helical form similar to that of the "tusk" of a narwhal. In the wild, species can be found growing on shaded rocky hillsides or cliffs, on the ground, in rock crevices, and almost anywhere the seed can germinate and grow. For the home, there are now many hybrids of various colours and forms available.
Although generally referred to simply as "Streptocarpus" or "Streps", the common name for subgenus Streptocarpus is Cape primrose, referring to the nativity of several species to South Africa and their superficial resemblance to the unrelated genus Primula. The common name for subgenus Streptocarpella is nodding violet. Streptocarpus sect. Saintpaulia ("African violet") is a separate section within Streptocarpus subgenus Streptocarpella.
