Reported in 2001 by E. L. Tisch, this variety of the spotted coralroot is described as follows: "It occurs in foggy rainforests bordering the Pacific coast of the north Olympic Peninsula. Unlike typical C. maculata, its flowers are consistently non-spotted, with a narrow, white labellum bearing two apical undulations and low, non-rugose basal lamellae. ... Corallorhiza maculata var. ozettensis grows in moist, foggy, very shady to moderately illuminated forests bordering the northwest coastline of the Olympic Peninsula. The collection sites, all within 300 m of the Pacific Ocean, are overstoried by mixture of Picea sitchensis, Thuja plicata, Tsuga heterophylla in the tree layer; Vaccinium alaskense, V. ovatum, V. parvifolium and Menziesia ferruginea in the shrub layer. The common herb associates are Blechnum spicant, Polystichum munitum, Maianthemum dilatatum, Tiarella trifoliata, Listera caurina, and L. cordata." (Tisch 2001)
