Discussion | Triteleia hyacinthina is one of the most widely distributed members of the genus, common in low, moist places such as meadows, vernal pools, and along streams, and found occasionally in drier valley grasslands, foothill woodlands, and closed-cone pine forests. It is cytologically and morphologically variable, with large-flowered forms found in wet places; smaller, scabrous forms found in dry places; forms with rather long pedicels (sometimes recognized as var. lactea); and forms with filaments lacking dilated triangular bases. Most plants have white flowers, but a few interesting forms with restricted distributions have lilac, blue, or even purple flowers. Triteleia ×versicolor Hoover is a sterile hybrid of T. ixioides and T. hyacinthina found in Monterey. Triteleia lilacina is recognized here as a species distinct from T. hyacinthina because of its different base chromosome number (2n = 16) and presence of hyaline vesicles (R. F. Hoover 1955).

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.
