Talinaceae

Talinum tenuissimum

The Talinaceae are a family in the order of the clove -like ( Caryophyllales ) within the angiosperms. They occur in the Neotropics, Africa and Asia.

  • 3.1 Notes and references

Description

There are shrubs, some species are subshrubs, annual or perennial herbaceous plants. The Talinella species are climbing shrubs. They are more or less deciduous. Some species produce tubers as outlasting. In the axils two scales are present. The change-constant leaves are often somewhat fleshy. It is formed a capsule fruit.

There are tannin cells present. Some of the species are CAM plants and the other C3 plants. The chromosome sets amount to n = 8

System

Outer systematics

Previously, these species were incorporated into the family of Portulakgewächse ( Portulacaceae ). Molecular biological studies have suggested that the family Talinaceae yields a monophyletic taxon. There only remains the genus purslane ( Portulaca ) in the resulting monophyletic family of Portulacaceae. ( Applequist et al. 2006 Nepokroeff et al. 2002)

Within the order of the clove -like ( Caryophyllales ) the Talinaceae are closely related to the Halophytaceae, Didiereaceae, Cactaceae, Halophytaceae, Portulacaceae, Montiaceae and Basellaceae; these eight families can be summarized as subordination Portulacineae. The former is divided into the genus Talinum section Phemeranthus Raf. is once again a separate genus in the family of Phemeranthus Montiaceae and clearly delineated data by molekurgenetische.
