Pursh (1813: 669) adopts the illegitimate Blechnum boreale Willd. (Sp. Pl. 5: 408. 1810) for the Lewis and Clark specimens gathered at Fort Clatsop, Clatsop Co., Oregon, on 20 Jan 1806 (Moulton, 1990: 223-225) while Meehan (1898: 47) reports this as Lomaria spicant (L.) Desv. (in Ges. Naturf. Freunde Berlin Mag. Neuesten Entdeck. Gesammten Naturk. 5: 325. 1811). PH-LC 41 has a label in the hand of Charles Pickering, similar to other Pickering labels for specimens from the herbarium of L.D. von Schweinitz, that indicates the specimens came from Collins. The label also says "Am. Lewis Herbar." which we take to mean the sheet is a duplicate of an authentic Lewis collection. The Collins material consists of both fertile and sterile fronds while the American Philosophical Society specimen (PH-LC 40) has only a single, small, sterile frond. We assume the species was collected only once.
