Krameria is a genus of flowering plants belonging to the family Krameriaceae. It consists of about 15 species, primarily found in arid regions of South America, particularly in countries like Argentina and Bolivia. These plants are known for their unique, woody stems and small, tubular flowers that can be purple or white. The most notable species within this genus is Krameria triandra, commonly known as rhatany. This plant is valued for its roots, which contain tannins and have been used traditionally in herbal medicine and as a dye. Krameria species typically thrive in dry, sandy soils and are adapted to withstand harsh environmental conditions.
