Adiantum capillus-veneris can be distinguished from Adiantum aleuticum, the only other Adiantum species in B.C., by its lax drooping habit, unbranched stem, arrangement of pinnae on both sides of the stem, and pinnules that are oval to fan-shaped (Brunton 1984). A. aleuticum is a taller, upright fern, which has a palmately-branched (equally two-forked) stem with oblong, almost rectangular (2-4 times longer than wide) pinnules. The two Adiantum species are not likely to be confused because they occupy different habitats: A. aleuticum occupies shaded acidic woods and rocky slopes while A. capillus-veneris is a calciphile, growing in seepy sites on calcareous rocks, including tufa (Brunton 1984).
