The Limeaceae are a family in the order of the carnation-like (Caryophyllales) within the flowering plants . There are only two genera with 23 to 38 species. The areas of Limeum range from the Capensis to Ethiopia , across the Arabian Peninsula to the Indian subcontinent and southern Asia; Macarthuria is found in Australia .

Description and ecology

They are annual to perennial herbaceous plants or subshrubs . The alternate and spirally or almost against constantly on the stem axis arranged leaves are simple and in some species they are reduced to scales. Stipules are missing.

The flowers are usually in zymose inflorescences together. The small, radially symmetrical , hermaphrodite flowers are five-fold. There are usually five free sepals . Petals may be missing, less often three to five are present. The stamens are fused together at their base. Two to seven carpels are an above-permanent (syncarp) ovary grown. There are one to three apotropic ovules per carpel.

A capsule fruit or split fruit is formed. In some species the seeds have an aril . The seeds are spread mostly through endozoochory .

The basic chromosome number is x = 9. They contain betalaine .

Systematics

These species used to be part of the Molluginaceae or Aizoaceae family . So far the genus Limeum ​​was classified in the tribe Limeeae, which was published in February 1840 by Eduard Fenzl in Stephan Friedrich Ladislaus Endlicher : Genera plantarum ... , 976, as "Limeae". Molecular biological studies have suggested that the Limeaceae family makes a monophyletic taxon . The family name Limeaceae was published on May 20, 2005 by Alexey Shipunov in James L. Reveal : The Botanical Review, interpreting botanical progress (Lancaster) , Volume 71, p. 128. The type genus is Limeum L.

The Limeaceae family contains only two genera with 23 to 38 species:
