| Cochlearia groenlandica L. | |
| Publ. & Syn. | Cochlearia officinalis auct., non L. (1753). |
| Notes | Linnaeus' Cochlearia groenlandica was described with "Habitat in Norvegia, Islandia, Groenlandia" (Linnaeus 1753: 647), and with reference to three earlier sources: Hortus Cliffortianus (1738), "Barth. act." with a reference to a Danish plant (Alholm), and Boerhaave's Index of plants in the Leyden garden (1720). It is improbable that any of these earlier sources refer to the arctic plants. The only specimen relevant as original material (LINN) is in bad condition and without indications of origin. This specimen has been designated as lectotype but with an epitype from western Greenland to confirm the current usage of the name (Elven and Nordal in Jonsell and Jarvis 2002). Cochlearia groenlandica is mainly high-arctic, in Europe restricted to the Norwegian and Russian arctic islands. Cochlearia sessilifolia was accepted by Al-Shehbaz and Koch (2010) but seems to be based on very few collections, perhaps only one, within the range of the polymorphic C. groenlandica in northwestern Alaska. Its characters as reported by the authors above (annual, fruit shape and size, stem structure, sessile cauline leaves, blade margin) are within the range we have observed in C. groenlandica. |
