Discussion

What appear to be hybrids between Tofieldia pusilla and T. coccinea occasionally occur in Greenland and the Northwest Territories. They are characterized by a leafy bract at or near the middle of the stem and enlarged, crimson bracts below the pedicels. In some suspected hybrids, the bracts are absent, and fused bracteoles, trunctate or lobed, sheathe the pedicels well below the flowers.
