Cycladenia humilis is the sole member of the monotypic genus Cycladenia. Known by the common name Sacramento waxydogbane, it is an uncommon plant native to the southwestern United States, especially California. It is found at some elevation in several mountain ranges in the region. One of the three varieties of this plant, called the Jones waxydogbane, is considered a threatened species. This is a fleshy perennial herb with dull green leaves and pinkish lavender flowers. The flowers begin as rolled tubes shaped like pea pods and then open into colorful funnel-shaped blooms.
