Vegetative characteristics

The fattened herb species are small annual or perennial herbaceous plants . They often form lawns . The stems are prostrate or ascending.

The leaves are opposite and fused at the base. The leaf shape is linear or sub-like. The tip of the leaf can be a spike tip. The blade is bare or ciliate on the edge. Stipules are missing.

Generative characteristics

The flowers are solitary or in little-flowered dichasias . The flower stalks are thin, usually upright or, after the anthesis, bent downwards like a hook below the calyx, and the stalk bends upwards again when the fruit is ripe.

The hermaphrodite flowers are four or five-fold, usually with a double flower envelope , the petals are rarely missing. The five sepals are free and blunt, less often with a short point. The five petals are entire and white, often very small and sometimes absent. There are four, five, eight or ten stamens present. At the bottom they have a nectar gland . Four or five carpels are an egg-shaped ovary grown. There are also four or five styluses.

The capsule fruits are egg-shaped and open with four or five lobes. The fruit valves are blunt. The numerous seeds are dark brown and kidney-shaped with a diameter of 0.2 to 0.5 millimeters.

ecology

The flowers are homogeneous , protandric or protogynous . The opening time ( anthesis ) is usually short. The pollination is effected by insects ( Diptera or Apoiden ) or by self-pollination ( Autogamie ).

Diaspores are the seeds. The seeds are spread by animals ( endozoochory ) or wind ( anemochory ).

Systematics

The genus Sagina was established in 1753 by Carl von Linné in Species Plantarum , p. 128. A synonym for Sagina L. is Spergella Rchb. The genus Sagina belongs to the tribe Alsineae in the subfamily Alsinoideae within the family Caryophyllaceae .
