Basellaceae

Basellaceae is a small family of flowering plants in the order Caryophyllales. This family contains about four genera and 20 species. The plants are primarily native to tropical and subtropical regions of the Americas, with a few species extending into Africa. Basellaceae are characterized by their herbaceous or climbing habit, with succulent leaves and stems. The flowers are typically small and inconspicuous, lacking petals but possessing prominent sepals that often resemble petals. The fruit is a small, fleshy berry.

The most well-known genus in the family is Basella, which includes Basella alba, commonly known as Malabar spinach or Ceylon spinach. This species is widely cultivated as a leafy vegetable in tropical and subtropical areas, valued for its mild flavor and ability to tolerate heat. Another genus, Ullucus, contains Ullucus tuberosus, a tuber-producing plant native to the Andes. Its starchy tubers are an important food source in that region, sometimes referred to as ulluco. Anredera is another genus with several species, some of which are used ornamentally or medicinally. The family is generally considered to be of minor economic importance overall, with the exception of Malabar spinach and ulluco in their respective regions. Research into the family's genetics and biogeography continues to refine our understanding of its evolutionary relationships.
