WHITE FRINGED ORCHID
Habenaria blephariglottis of Michigan Flora.
Only in sphagnum bogs, seldom much shaded though often associated with black spruce and tamarack.
This species is often difficult to distinguish from P. ciliaris when the specimens are dry, if there is no note as to the color of the fresh flowers. See notes under Platanthera ciliaris for hybrids. Platanthera ×vossii Case is a hybrid with P. clavellata known from northern Michigan (Case 1983).
Rarely, the lip is entire in this species (forma holopetala (Lindl.) P. M. Br. This form might be thought to be the hybrid Platanthera ×vossii, which, however, has vestigial fringes on the lip (unless the hybrid were to be formed with the rare forma holopetala!), and has smaller flowers tilted in the spikes somewhat like those of P. clavellata.
