|discussion=<p>Triteleia laxa is very common at low altitudes in central California, growing under a variety of ecological conditions, with wide attendant variation, especially in flower size. It could be considered a species complex (like T. ixioides) made up of many forms, with consistent differences in chromosome number and in the size and shape of the anthers (M. P. Burbanck 1944). The flowers can be quite large or small, and usually are pale blue, but sometimes are white or deep bluish purple. These morphologies often intergrade, making it difficult to recognize formal varieties.</p><!--
--><p>This species may occur in southwestern Oregon, but documentation of its presence there is lacking.</p><!--
--><p>Triteleia ×tubergenii L. W. Lenz is a cultivated amphidiploid hybrid between T. laxa and T. peduncularis (L. W. Lenz 1970).</p>
