''Sagina'' (like ''Colobanthus'' called "pearlworts") is a genus of 20–30 species of flowering plants in the pink or carnation 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, growing to 5–15 cm. 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 four or five green sepals and an equal number of white petals; the petal size relative to the sepal size is useful in species identification. The fruit is a small capsule containing several seeds.〔Huxley, A., ed. (1992). ''New RHS Dictionary of Gardening''.
