Discussion

Triteleia bridgesii is similar to T. laxa and in herbarium specimens can be distinguished only by the stamens. However, in fresh flowers, the perianth lobes of T. bridgesii spread abruptly from the throat of the perianth tube, unlike those of T. laxa, and the flowers of T. bridgesii are erect, while those of T. laxa are oriented horizontally. Triteleia bridgesii flowers a month earlier than T. laxa where they both occur in the Sierra Nevada foothills. The flowers in specimens of T. bridgesii from Humboldt County are unusually long, which accounts for the wide ranges of measurements for the perianth.

Plants of Triteleia crocea from the Trinity Mountains of northern California differ from others of the species in having pale blue perianths instead of yellow ones, with lobes slightly fringed toward the apex instead of entire. These plants first were assigned to a separate species, and subsequently have been transferred to this one, where clearly they belong. Formal recognition at subspecific rank may prove desirable in future.
