Triteleia is a genus of monocotyledon flowering plants also known as triplet lilies. The 16 species are native to western North America, from British Columbia south to California and east to Wyoming and Arizona, with one species in northwestern Mexico. However, they are most common in California. They are perennial plants growing from a fibrous corm roughly spherical in shape. They get their name from the fact that all parts of their flowers come in threes.
