Discussion

Variety nemoralis is often found near var. rubiginosa with apparently little or no ecological distinctions between them. They differ in morphological characters by degrees of expression rather than complete distinctions. The rank of variety follows, for example, the recommendation of H. J. Scoggan (1978–1979).
