Viola macloskeyi
Viola odorata
Viola macloskeyi was described by Banks in 1824 as V. rotundifolia var. pallens, from specimens collected by Banks in Labrador. E. Brainerd made the combination V. pallens in 1905 and later (1924) detailed its troublesome nomenclatural history.
Viola macloskeyi was described in 1895 by F. E. Lloyd based on specimens collected at the base of Mount Hood, Oregon. M. S. Baker (1953) placed V. macloskeyi as a subspecies of V. pallens. He later (1953b) corrected that change based on priority and thus the taxon became known as V. macloskeyi subsp. pallens. N. H. Russell (1955) maintained that status, separating subspp. macloskeyi and pallens on the wider, spreading basal leaf lobes of subsp. pallens. McKinney, after examining specimens of both taxa, including types, concluded that the differences have been exaggerated and fall within the range of variation of a single species.
Viola macloskeyi occurs in small colonies; individual plants are interconnected by stolons.
In parts of its range, Viola macloskeyi often shares habitat with V. renifolia; it may be difficult to distinguish the two. The stolons of V. macloskeyi are useful for identification during summer months; V. renifolia plants lack stolons. Patterns of indument can be useful; V. renifolia is usually hairy and V. macloskeyi is usually glabrous (petioles sometimes pubescent).
Viola macloskeyi reportedly hybridizes with V. primulifolia var. primulifolia (= V. ×mollicula House).

Viola odorata occurs in small colonies; individual plants are interconnected by stolons.
The flowers of Viola odorata are noted for their fragrance; some plants are more fragrant than others. It is native to Eurasia and assumed to be introduced in North America where it is usually found in areas associated with human habitation, including parks, lawns, and roadsides. A substantial industry revolved around the commercial production of violets in England, France, and the United States from prior to 1895 and into the 1900s (R. E. Coombs 2003). Viola odorata is sometimes found in remote locations not easily explained by anthropogenic influence, for example, Clearwater Mountains, Idaho. It is available through the nursery trade and is cultivated as a garden plant and occasionally reported as an escape. Viola odorata is grown in southern France for essential oils used in perfumes, flavorings, and toiletries, and also for the production of the sweet, violet-colored liqueur called parfait amour (V. H. Heywood 1978).
