Krameria are found across the Americas, with most native to the tropical regions. They are perennial shrubs which act as root parasites on other plants. The flowers have glands called elaiophores which produce a lipid which is collected by bees of the genus Centris as they pollinate the flowers. The genus Centris contains over 110 species of large apid bees occurring from Kansas to Argentina.

- Krameria argentea - para rhatany
- Krameria cystisoides
- Krameria erecta - Pima rhatany, purple heather, littleleaf rhatany
- Krameria grayi - white rhatany
- Krameria ixine - abrojo colorado
- Krameria lappacea - para rhatany
