In the book Flora of the city of Oulu (Väre et al. 2005) was published a list of all vascular plants encountered in the city including the first record. While preparing the list we had at our disposal unpublished manuscripts including many prima loca plantarum which are published now in their original form. Many of the records were cited shortly e.g. by Hjelt’s Conspectus (Hjelt 1888–1926).
