Triantha glutinosa
Triantha racemosa
Hybrids between Triantha glutinosa and T. racemosa occur in Burlington County, New Jersey; see note under T. racemosa. On the Queen Charlotte Islands in British Columbia, there appears to be some evidence of hybridization between T. glutinosa and the two subspecies of T. occidentalis that occur there.

Specimens of Triantha collected in Burlington County, New Jersey, have generally been determined as T. racemosa. However, the population is variable, and while there are aspects in some of these plants suggestive of T. racemosa that would explain the determinations, others are closer morphologically to T. glutinosa. This is seen in the typical “glutinosa” glands, the narrower, less-spreading bracteoles that usually lack glandular hairs, the more-ascending pedicels, the shorter internodes in most inflorescences, and the chartaceous capsules. I suppose that in the past the two species had overlapping ranges in this northeastern region where they no longer are found, and that some hybridization between T. glutinosa and T. racemosa has occurred. The Burlington County population is a surviving disjunct remnant with attributes of both species. The specimens have been annotated T. glutinosa × T. racemosa, and New Jersey is omitted from the list of states in which T. racemosa is found.
