Purslane (Family Portulacaceae)
Portulacaceae is a family of flowering plants in Order Caryo-
phyllales, comprising about 20 genera with about 500 species, rang-
ing from herbaceous plants to shrubs. The family has been recognis-
ed by most taxonomists, and is also known as the Purslane Family.
The family is very similar to Family Caryophyllaceae.
Family Portulacaceae has a cosmopolitan distribution, with the
highest diversity in semi-arid regions of the Southern Hemisphere
in Africa, Australia, and South America, poorly represented in Eur-
asia, with a few species also extending north into Arctic regions.
A few cultivated ornamentals (e.g., Portulaca grandiflora, Talinum,
Lewisia and Calandrina spp.), and Portulaca oleracea constitutes a
potherb and salad green.
