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.
