Solandra is a genus of flowering plants in the nightshade family, Solanaceae. It is named after the Swedish naturalist Daniel C. Solander. The vines it contains are commonly known as chalice vines and are native to the Caribbean, Mexico and South America. They have very large flowers and glossy foliage. Also called Cup of Gold. It was once (and likely still is) used by the Huichol of Mexico and other tribes of the region where it is known by the name "kieli" or "kieri" with some archaeological evidence supporting the theory that its use predates that of "Peyote" .
