Sagina (pearlwort) is a genus of 20–30 species of flowering plants in the family Caryophyllaceae. These are flowering herbs native to temperate regions of the Northern Hemisphere extending south to tropical mountain areas at high altitudes, reaching just south of the equator in Africa. They are small annual or perennial herbaceous plants, erect or prostrate, growing to 5–15 cm tall or broad. The leaves are opposite, often in tight whorl-like clusters, simple linear, typically 5–20 mm long. The flowers are solitary or in small cymes, with five green sepals and five white petals; the petal size relative to the sepal size is useful in species identification. The fruit is a small capsule containing several seeds.[1][2][3][4]
