Goodyera repens
Goodyera oblongifolia
Two varieties of Goodyera repens have been recognized: individuals with plain green leaves as var. repens and those with leaf veins bordered by broad white bands as var. ophioides Fernald. Many specimens from western North America are intermediate in this character: the bands bordering the veins are extremely narrow and almost indistinguishable by color from the leaf blade proper. Most specimens from eastern North America have obviously white-reticulate leaves, and most specimens from western Canada have plain green leaves (some with darker green veins). At several localities in western North America, plants with plain green leaves and plants with faintly reticulate leaves are found together (W. J. Cody 1961). Individuals with faintly reticulate leaves and those with plain green leaves are often found on the same herbarium sheet and, infrequently, both kinds of leaves occur on the same plant. Because of this variation in the degree of white reticulation, the varieties are not recognized here. Individuals with plain green leaves, obviously white-reticulate leaves, and intermediate leaves occur in Alaska.

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.
