Discussion

In eastern North America, Goodyera oblongifolia is restricted to formerly glaciated areas.

Plants with leaves white-reticulate on the lateral veins have been described as Goodyera oblongifolia var. reticulata. This segregate, essentially coastal in distribution, occurs from northern California to southeastern Alaska and is less frequent inland from British Columbia to New Mexico and in Michigan and Wisconsin. Because garden transplant experiments (J. A. Calder and R. L. Taylor 1968, vol. 1) have shown that both reticulate and non-reticulate leaves are found within the same clone, varieties are not recognized.
