Abstract: Blechnum spicant var. fallax Lange is a fern taxon endemic to Iceland where it occurs in the vicinity of hot springs on geothermally heated soils. Te taxon was first described by a Danish botanist Johan Martin Christian Lange in 1880 on the basis of plant material collected by Christian Grønlund in Iceland. Because its holotype was not designated in the protologue, we examined the extant original material including illustrations from Flora Danica and a single plant on sheet C10021769 (deposited in C) that was the basis for the respective plate. We select this specimen as the lectotype of Blechnum spicant var. fallax.
