pivaras

Pivaras is a genus of flowering plants in the family Brassicaceae. The genus was first described in 1983 by Ihsan A. Al-Shehbaz. Plants in this genus are typically small, herbaceous annuals or biennials. They are native to western North America.

The genus Pivaras is characterized by its small, usually white or yellow flowers with four petals arranged in a cross shape, typical of the Brassicaceae family. The leaves are often lobed or toothed and arranged in a basal rosette. The fruit is a silicle, a type of dry fruit characteristic of the mustard family, which splits open to release small seeds.

Species within Pivaras are found in a variety of habitats, often in arid or semi-arid regions, including deserts, grasslands, and open woodlands. They are generally adapted to dry conditions and can be found growing in sandy or rocky soils.

The taxonomic classification of Pivaras places it within the tribe Euclidieae. While not widely cultivated, some species may have minor ecological roles in their native environments. The genus is relatively small, with a limited number of recognized species. Further research may continue to refine the understanding of its evolutionary relationships and distribution.
