Triteleia is a genus of monocotyledon flowering plants also known as tripletlilies . Species are native to western North America, from British Columbia southwards, with the ranges of some species reaching to Guatemala. 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.

Taxonomy and systematics

The systematics of this genus are problematic in two ways.

First, different current systems place the genus in three different families. The Angiosperm Phylogeny Group place it in family Asparagaceae or optionally in the possibly distinct Themidaceae. Many other modern authors place it in the family Alliaceae. All these families are in the order Asparagales. However, older but still widely used sources such as ITIS place the Tripletlilies in the family Liliaceae, in the order Liliales.

The second difficulty is taxonomical;some common species that are now placed in genus Triteleia were formerly placed in genus Brodiaea, and as a consequence "brodiaea" has been incorporated into their common names. About 15-20 species are currently recognised in Triteleia, with several of them having well defined subspecies or varieties that have different common names.
