CHECKLIST OF THE VASCULAR PLANTS OF FINLAND, based on Kurtto, A. & Lahti, T. 1987: Suomen putkilokasvien luettelo (Checklist of the vascular plants of Finland). - Pamphl. Bot. Mus. Univ. Helsinki 11: I.-VI + 1-163. The list includes all the vascular plants found in Finland up to 1987, excluding those only in cultivation (i.e. taxa found during the past few years - mainly casual plants or plants escaping from cultivation are missing, and erroneous records of the 1987 list have not been corrected)
