Hybrids between
Phyllodoce empetriformis
and
P. glanduliflora
are encountered occasionally where the two species occur together. The hybrids,
P.
×
intermedia
(Hooker) Rydberg, consisting largely of first-generation crosses (F
1
progeny), have a decidedly intermediate floral morphology, combining glandular, mostly nonciliate sepals more than 3 mm long and pinkish, cylindric to ovoid corollas.
