Jaakko Nurmi’s scientific contributions

Distribution and ecology of 72 species, subspecies and established hybrids of Geraniaceae (3), Linaceae (1), Balsaminaceae (1), Malvaceae (2), Clusiaceae (1), Violaceae (8), Tamaricaceae (1), Elatinaceae (1), Onagraceae (11), Haloragaceae (2), Hippuridaceae (1), Cornaceae (1), Apiaceae (11), Diapensiaceae (1), Pyrolaceae (6), Ericaceae (15), Empetraceae (2), and Primulaceae (4) in Inari Lapland, northernmost Finland are described, with notes on their morphology, variation, taxonomy, hybridization and dependence on culture. Kalmia polifolia Wangenh. is presented as new to Finland, and Cicuta virosa L. var. virosa as new to Inari Lapland. Four species, Androsace septentrionalis L., Heracleum sphondylium L. s. str., Peucedanum palustre (L.) Moench and Viola rupestris F. W. Schmidt, which sometimes have been reported from Inari Lapland, are here not accepted to the flora of the province.

Two new diploid (2n=34) subspecies of Campanula rotundifolia L. are described from North Europe. C. rotundifolia subsp. fennica Piirainen & Nurmi is native in the southern half of Finland, adjacent parts of the Karelian Republic (Russia), northern Estonia and the Baltic Islands (Sweden, Estonia, Russia). Its habitats are cliffs and eskers, in the Baltic area also alvars. It is ahemerobic or even hemerophobic. C. rotundifolia var. latifolia Brenner and f. pusilla Saelán (nom. illeg.), are synonymized under it; the latter is also lectotypified. The other new subspecies, subsp. kemensis Piirainen & Nurmi, is known from the northern half of Finland, adjacent Sweden, Finnmark (North Norway), and the Kola Peninsula (Russia). The native habitats are alluvial river shores and cliffs. As an apophyte, it grows also in meadows, hayfields, roadsides and villages. In addition, a lectotype is chosen for C. rotundifolia f. lapponica Witasek, a northern diploid form described based on East Fennoscandian material. The original material in H consists of specimens belonging to three different taxa or their intermediates. The lectotype was chosen in accordance with the original description to stabilize the use of the name. The name is synonymized to the newly described subsp. kemensis, representing one extreme end of its variation.

Distribution and ecology of 63 taxa of Rosaceae (39) and Fabaceae (24) in Inari Lapland, northernmost Finland are described, with notes on their morphology, variation, taxonomy, hybridization and dependence on culture. Lathyrus palustris L. ssp. pilosus (Cham.) Hultén is presented as new to Finland, and 7 taxa, Alchemilla baltica Sam. ex Juz., A. glabra Neygenf., A. plicata Buser, Filipendula vulgaris Moench, Potentilla anserina L. ssp. anserina, Galega orientalis Lam., and Vicia villosa Roth ssp. villosa, as new to Inari Lapland.

Distribution and ecology of 53 species, subspecies and hybrids of Brassicaceae (33), Droseraceae (3), Crassulaceae (1), Saxifragaceae (11), Parnassiaceae (1) and Grossulariaceae (4) in Inari Lapland, northernmost Finland are described, with notes on their morphology, variation, taxonomy and hybridization.
