Discussion

Because of confusion with similar, insufficiently studied, glabrous-inflorescence forms, the distribution given is inclusive.

Variety phoeniceoides in the strict sense is, in general appearance, like typical forms of var. chrysocarpa but is completely glabrous and, uniquely for this species, has the larger bracteoles stipitate-glandular like those in the Crataegus dodgei group.
