Tofieldia glutinosa (Michx.) Pers. x T. racemosa (Walter) Britton, Sterns & Poggenb.

Specimens from the iclict population of Tofieldia in Burlington Co.,, New
Jersey, have generally been determined as T. racemosa. This is somewhat puzzling, for
while the population is variable, and there are aspecs in some of these plants strongly
suggestive of T. racemosa, that would explain the determination, the majority are much
'glutinosa' pubescence (note adhering panicles rarely present in T. racemosa); the
narrower, less spread bracteoles that generally lack glandular hairs; the more ascending
pedicels; the shorter intemodes in most inflorescences; and the capsules. I would
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
by T. racemosa occurred. The Burlington Co. population is a surviving disjunct
remnant, and contains genes from both species. John G. Packer - April 16,1991.
