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.

Subspecies 5 (5 in the flora). As defined by L. W. Lenz (1975, 1976b), Triteleia ixioides consists of five groups of plants that, although readily recognizable as a rule, often cannot be separated by constant characters. Subspecies ixioides and subsp. cookii are strictly coastal and widely separated geographically from the three subspecies of the interior. They flower from May to August (a month earlier than subsp. scabra) and usually are found in the shade of oaks, cypresses, or pines. Polyploidy is rampant and perhaps indicative of the geographical and ecological differentiation of these morphologically similar subspecies.
