Hokkanen, P. J. 2003: Vascular plant communities in boreal herb-rich forests in Koli, eastern Finland. — Ann. Bot. Fennici 40: 153–176.
Herb-rich forests have aroused great interest in maintaining the biological diversity of boreal forests. The ecology and structure of these ecosystems are poorly known, and no systematic assessment of their characteristics has been made. In order to explore the structure of vascular plant communities, 101 sample plots in 57 herb-rich forest areas were studied in Koli, eastern Finland. The material was classified with two-way indicator species analysis (TWINSPAN) and ordinated with detrended correspondence analysis (DCA). The results suggest that many environmental variables; e.g. varying topography and bedrock affected the herb-rich forest vegetation. The most important compositional gradients were moisture, fertility and shading. According to species composition, the Koli area is an important patch for species dispersion from south to north. The study area is valuable for maintaining threatened forest flora and eastern elements. In particular, the unique Diplazium sibiricum communities and other taiga species deserve special attention. The site types (ecological groups) corresponded quite well to the herb-rich forest types described in literature.
Kutnar, L. & Martinçiç, A. 2003: Ecological relationships between vegetation and soil-related variables along the mire margin–mire expanse gradient in the eastern Julian Alps, Slovenia. — Ann. Bot. Fennici 40: 177–189.
In the NW part of Slovenia, at the southern border of the Sphagnum-mire area in Europe, the plant species diversity and vegetation structure of mires (sedge fen, spruce mire and dwarf-pine bog) and spruce forests were investigated using ordination techniques (detrended correspondence analysis, DCA). The mires studied occur at around 1200 metres above sea level. The correlation between plant distribution patterns and ecology, with particular reference to soil variables, was examined. Based on DCA ordination, the sedge fens were clearly distinguished from the dwarf-pine bogs and the spruce mires, as well as from the spruce forests on the mineral soils. A significant correlation between the first DCA axis and the plant species diversity was found. The Shannon diversity index and the species richness were highest in the sedge fen and on the mire-forest border zone. The first DCA axis was interpreted as a reflection of the gradients of the soil pH, the amount of calcium and the base saturation level. The first axis clearly differentiated the Sphagnum species (e.g. S. girgensohnii, S. magellanicum, S. russowii, S. flexuosum, S. capillifolium) from the moss species belonging mostly to Amblystegiaceae (e.g. Drepanocladus cossonii, Campylium stellatum, Calliergon cordifolium, Cratoneuron decipiens). The second DCA axis was interpreted in terms of the soil water content, total carbon content, C/N ratio and peat depth. It evidently differentiated the spruce forest on the mineral soil from the various mire ecosystems.
Moon, H.-K. & Hong, S.-P. 2003: Pollen morphology of the genus Lycopus (Lamiaceae). — Ann. Bot. Fennici 40: 191–198.
The pollen morphology of 15 species (34 specimens) of the genus Lycopus (Lamiaceae, Mentheae) was studied and documented in detail using light microscopy (LM), scanning electron (SEM), and transmission electron microscopy (TEM). The pollen is mostly medium or sometimes small in size, with a circular amb, oblate to prolate in shape, hexacolpate with granular membranes; the exine is bi-reticulate, with unbranched columellae and a continuous, lamellated endexine. The results indicate that Lycopus is stenopalynous; thus the value of pollen characters for taxonomic applications is limited. Some phylogenetic relationships with other related taxa within the tribe Mentheae are also briefly discussed.
Nurminen, L. 2003: Macrophyte species composition reflecting water quality changes in adjacent water bodies of lake Hiidenvesi, SW Finland. — Ann. Bot. Fennici 40: 199–208.
The manifold role of aquatic macrophytes in lake ecology is closely linked to their distribution and biomass, which in turn is a synergy of various environmental factors. The implication of different environmental variables on macrophyte speciation and life form structure in lake Hiidenvesi, with an uneven eutrophication history, was studied. The persisting life forms reflected the somewhat inherently turbid water: emergent and floating-leaved species were common, whereas submerged species were scarce and low-light tolerant dominated. Effects of uneven nutrient loading were noticeable amongst the interconnected basins of the lake: the shallow, northernmost basins are most turbid and eutrophic, and the steeper westerly basins are in turn less eutrophicated and more clear-water. Increased nutrient level and turbidity together with softening of bottom substrate have emphasized the speciation to more eutraphent species and pleustophytes, especially in the most eutrophic Kirkkojärvi basin.

Harmaja, H. 2003: Notes on Clitocybe s. lato (Agaricales). — Ann. Bot. Fennici 40: 213–218.
Agaricus nebularis Batsch : Fr. is approved as the lectotype of the genus Clitocybe (Fr.) Staude (Agaricales: Tricholomataceae). Lepista (Fr.) W.G. Smith is a younger taxonomic synonym. Diagnostic characters of Clitocybe are discussed; among the less known ones are: (i) a proportion of the detached spores adhere in tetrads in microscopic mounts, (ii) the spore wall is cyanophilic, and (iii) the mycelium is capable of reducing nitrate. Three new nomenclatural combinations in Clitocybe are made. The new genus Infundibulicybe Harmaja, with Agaricus gibbus Pers. : Fr. as the type, is segregated for the core group of those species of Clitocybe s. lato that do not fit to the genus as defined here. Infundibulicybe mainly differs from Clitocybe in that: (i) the spores do not adhere in tetrads, (ii) all or a proportion of the spores have confluent bases, (iii) all or most of the spores are lacrymoid in shape, (iv) the spore wall is cyanophobic, and (v) the mycelium is incapable of reducing nitrate. Thirteen new nomenclatural combinations in Infundibulicybe are made. Two new nomenclatural combinations are made in Ampulloclitocybe Redhead, Lutzoni, Moncalvo & Vilgalys (syn. Clavicybe Harmaja), a recent segregate of Clitocybe.
