| Crepis multicaulis Ledeb. | |
| Publ. & Syn. | Ledeb., Icon. Pl. 1: 9, t. 36 (1829). Described from the Altai, "in lapidosis insularum fl. Tschuja ex adverso ostii fluvii Kurai" (Siberia). |
| Notes | Crepis multicaulis was discovered in 1851 in Norway in a single, very isolated, and near-arctic small population at Meskelva in Nesseby, much discussed in phytogeography (e.g., Fægri 1962; Nordhagen 1963). The plant was last observed in this site in 1943 and has been assumed extinct from Norway. A Laane chromosome count (Laane and Høiland 1986) was fairly sensational at its time as it was made on an old herbarium specimen from this locality by quite advanced scanning electrone microscopy. The species was found in 2008 in a second, arctic population in Norway (Ryvarden and Iversen 2008), the population size estimated in 2009 to be ca. 1000 individuals. Crepis multicaulis must probably be transferred, together with, e.g., C. praemorsa, to one or more new "satellite" genera near Lagoseris, see Enke et al. (2008). |
