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.

Of conservation concern.

This is the only species of Triteleia occurring on any of the islands off the southern California coast; it is endemic to San Clemente Island.
