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.

Triteleia lilacina differs from T. hyacinthina in base chromosome number and in that the interior of the perianth tube is covered with hyaline vesicles (making a glassy nectary). In addition, T. lilacina has linear filaments and bluish purple anthers at anthesis, whereas T. hyacinthina tends to have triangular-dilated filaments and whitish to yellow (or rarely blue) anthers at anthesis.
