The tangled herbs or tangles ( Scleranthus ) are a genus of plants in the carnation family (Caryophyllaceae). Regarding the derivation of the German trivial name , it can be said that in German colloquial language a "ball" is a small (up to the size of a fist) bale of wound threads. The twelve or so species are widespread in Eurasia , North Africa and Australasia .

Vegetative characteristics
The Scleranthus species and subspecies grow as annual, biennial and perennial herbaceous plants or dwarf shrubs . The tap roots are thin. The stem -round stems are erect to prostrate and branched.
The constantly against arranged on the stem leaves are sessile and fused at their base pairs. The simple leaf blades are narrow, subulate to linear, not succulent, single-veined with a pointed or blunt upper end. Stipules are missing.
Generative characteristics
In terminal or lateral, zymous inflorescences , many flowers are loosely to close together. The opposite, foliage-like bracts are fused in pairs. There is at most a short flower stalk.
The hermaphroditic flowers are radial symmetry and five-fold with a double flower envelope . The flower cup (hypanthium) is jug-shaped and continues abruptly at its base. The five free, green to greenish, herbaceous sepals are 1.5 to 4 millimeters in length, lanceolate to subphrate and have a whitish, dry-skinned edge and a pointed to blunt upper end. Petals are missing. The two to ten free stamens are inserted on the edge of the flower cup. All of the stamens can be fertile or five to eight are converted to staminodes . A nectar-producing disc is present at the base of the stamens. Two carpels are a half under constant ovary grown, so sepals and stamens are perigynous. The two free styluses in each one capped, papillary scars.
The solitary fruit is tubularly enclosed by the slightly to heavily furrowed flower cup, which is crowned by the durable sepals and together forms the egg-shaped "Utricle", which remains closed when ripe and thus represents the diaspore . The seeds are yellow and spherical.
The basic chromosome number is x = usually 11, rarely 12.
Systematics and distribution
The genus Scleranthus was first published in 1753 by Carl von Linné in Species Plantarum , 1, p. 406; The wrong spelling "Schleranthus" was used in the heading. The botanical generic name is derived from the ancient Greek words scléranthe : σκληρός sklerós for "hard" and ἄνθος ánthos for "blossom" or "flower" and refers to the inflorescences. Type species is Scleranthus annuus L. A synonym for Scleranthus L. is Mniarum J.R. Forst . & G.Forst.
The genus Scleranthus belongs to the tribe Sclerantheae in the subfamily Alsinoideae within the family of the Caryophyllaceae .
The genus Scleranthus includes (ten to) about twelve (to 17) species. Around three species, the annual ball ( Scleranthus annuus ), the perennial ball ( Scleranthus perennis ) and the drift ball ( Scleranthus polycarpos ), each with a few subspecies, are native to the temperate areas of Europe and the Mediterranean. Of the others, about eight species are native to Australasia . Three to four species are naturally found in Australia, plus two neophytes. Some species are in the world in many areas, for example in North America , neophytes .
