Grayia

Description

Grayia is a genus of flowering plants that belong to the family Amaranthaceae. The genus was named after the American botanist Asa Gray. The species are native to the western United States and Mexico, and they are known for their small, inconspicuous flowers that are arranged in spikes. Grayia plants are unique because they have a woody stem, which is unusual for plants in the Amaranthaceae family. These plants are also drought-tolerant and can survive in arid regions with poor soil quality.
