Triteleia lemmoniae, common names Oak Creek triteleia,[2] Lemmon's star or Oak Creek triplet lily, is a plant species now classed in the family Asparagaceae,[1] although older classifications would have regarded it part of the Liliaceae.

[3] Triteleia lemmoniae is endemic to Arizona, the only member of the genus native to the state.

[3] The species is named for Sara Plummer Lemmon (1836–1923), a well-known American botanist.

Lemmon, lived and worked in Oakland, California but did extensive botanical explorations in Arizona.

Several species bear the epithet "lemmonii" in his honor; Triteleia lemmoniae and Mount Lemmon in Arizona were named in hers.
