|discussion=<p>A. E. Porsild (1939) recognized three varieties in <i>Pyrola grandiflora</i> (<i></i></i>var.<i><i> canadensis</i>, var. gormanii, and <i></i></i>var.<i><i> grandiflora</i>) differing subtly in leaf and floral morphology, floral fragrance, and habitat. Variation among these taxa appears to be essentially continuous. E. Haber (1972) referred them to synonymy [under P. rotundifolia <i></i></i>subsp.<i><i> grandiflora</i> (Radius) Andres] without discussion. Hybrids between <i>P. grandiflora</i> and <i>P. minor</i> have been reported from western Greenland; they were discussed by T. W. Böcher (1961).</p>
