Triteleia hendersonii is common within its restricted range. The plants previously recognized as var. leachiae, or separately as T. leachiae, differ primarily in having a white perianth and are limited to Curry County, Oregon. Intermediates have been found, and further study of this variation is required to determine whether formal recognition of infraspecific taxa is warranted.
