Concept Reference: Kartesz, J.T. 1994. A synonymized checklist of the vascular flora of the United States, Canada, and Greenland. 2nd edition. 2 vols. Timber Press, Portland, OR.
Concept Reference Code: B94KAR01HQUS
Name Used in Concept Reference: Adiantum aleuticum
Taxonomic Comments: Formerly included in Adiantum pedatum (under various names including A. pedatum var. aleuticum and A. pedatum var. calderi), but reproductively and morphologically isolated (C.A. Paris, Flora of North America, vol. 2, 1993). Accepted as a species by Kartesz (1994 checklist and 1999 floristic synthesis). Widespread but somewhat irregularly distributed in the American West, from Arizona, California, and Chihuahua north to Montana, Alberta, and Alaska; also occurring infrequently, primarily or exclusively on serpentine, in the northeastern U.S. and southeastern Canada. The true Adiantum pedatum (as presently interpreted) is eastern, ranging westward only to Minnesota, Nebraska, and Texas (see maps in Flora North America, vol. 2, 1993).
