Dai, Y. C., Niemelä, T. & Kinnunen, J. 2002: The polypore genera Abundisporus and Perenniporia (Basidiomycota) in China, with notes on Haploporus. — Ann. Bot. Fennici 39: 169–182.
The species of Abundisporus Ryvarden and Perenniporia Murrill (Aphyllophorales, Basidiomycota) from China are listed. A key was prepared for the 24 species so far recorded in the two genera from the country, including condensed descriptions and spore dimensions. Two new species are described and illustrated: Abundisporus quercicola Y.C.Dai and Perenniporia piceicola Y.C.Dai. The genera Haploporus Singer and Pachykytospora Kotl. & Pouzar are considered as synonymous, being closely related to Perenniporia but differing from it by ornamented spores. The following new combinations are proposed: Haploporus alabamae (Berk. & Cooke) Y.C.Dai & Niemelä, Haploporus papyraceus (Schwein.) Y.C.Dai & Niemelä, Haploporus subtrameteus (Pilát) Y.C.Dai & Niemelä, Haploporus tuberculosus (Fr.) Niemelä & Y.C.Dai, and Perenniporia subadusta (Z.S.Bi & G.Y.Zheng) Y.C.Dai.
Harmaja. H. 2002: Rhododendron subulatum, comb. nova (Ericaceae). — Ann. Bot. Fennici 39: 183–184.
Following the commonly accepted generic concept, the East Asian species Ledum subulatum (Nakai) A.P.Khokhr. & Mazurenko (Ericaceae) is transferred to the genus Rhododendron L. as Rhododendron subulatum (Nakai) Harmaja. A list of all species of Rhododendron subsect. Ledum (genus Ledum L.), according to current knowledge, is provided.
Jauhiainen, S., Laiho, R. & Vasander, H. 2002: Ecohydrological and vegetational changes in a restored bog and fen. — Ann. Bot. Fennici 39: 185–199.
The vegetation of two boreal mires drained for forestry was studied prior to and after restoration (removal of tree stand and filling in of ditches). The restoration induced a rapid rise in the water table level and caused relatively rapid changes in plant species composition and cover. On the minerotrophic fen site, the number of forest species declined and the cover of Eriophorum vaginatum increased five-fold, reaching over 50% cover in three years. On the ombrotrophic bog site, the terrestrial lichens disappeared, while the cover of Empetrum nigrum, Calluna vulgaris, Eriophorum vaginatum, and Sphagnum balticum increased. Changes in water table level and vegetation indicate a change towards a functional mire ecosystem.
Jørgensen, P. M. & Sipman, H. J. M. 2002: The lichen genus Erioderma in Southeast Asia. — Ann. Bot. Fennici 39: 201–211.
The lichen genus Erioderma has a centre of speciation in the islands of SE Asia. It is represented there by a total of ten species, seven of which are endemic. Four of the species are here described as new. All but two of the SE Asian species are closely related to South American species
Koff, T. & Punning, J.-M. 2002: The last hundred years of land-use history in Estonia as inferred from pollen records. — Ann. Bot. Fennici 39: 213–224.
The pollen composition of the uppermost part of sediments formed during the last hundred years in four lakes located in different landscapes (open agricultural land, forested area, ombrotrophic bog) in Estonia was studied. The pollen of land-use indicator taxa are arranged into three groups: indicators of cultivated land, ruderal communities, and meadow and pasture land. We established clear differences in the pollen proportions of cultivated, ruderal and meadow plants, depending on the intensity of human impact around studied site. The temporal changes of the share of different human impact pollen indicators show especially good correlation with the history of land-use when the changes took place in the immediate vicinity of the lake (Ruusmäe). In those areas close to the actively used arable land the proportion of Cerealia pollen may reach 6%–8% of the total pollen sum. Values of Cerealia pollen of 1%–2% reflect the background values for the region.
Kukwa, M. 2002: Taxonomic notes on the lichen genera Lepraria and Leproloma. — Ann. Bot. Fennici 39: 225–226.
The genus Leproloma Nyl. ex Cromb. is reduced to a synonym of Lepraria Ach. and all taxa of the former are transferred to the latter. The following new combinations are proposed: Lepraria diffusa (J.R.Laundon) Kukwa comb. nova var. diffusa, L. diffusa var. chrysodetoides (J.R.Laundon) Kukwa comb. nova and L. sipmaniana (Kümmerling & Leuckert) Kukwa comb. nova.
Liu, Y.-T., Li, R. & Long, C.-L. 2002: Pholidota niana (Orchidaceae), a new species from southeastern Yunnan, China. — Ann. Bot. Fennici 39: 227–229.
Pholidota niana Y.T.Liu, R.Li & C.L.Long, a new species of the Orchidaceae (Orchidoideae) from southeastern Yunnan Province, China, is described and illustrated. The differences and similarities between P. niana and the closely related P. longipes S.C.Chen & Z.H.Tsi are discussed.

Alchemilla ovitensis Y.Menemen & E.Hamzaoglu (Rosaceae) from the east Black Sea region (Turkey) is described as a species new to science and illustrated. Its geographic distribution is presented on a map and it is compared with five morphologically similar species.
Tahvanainen, T., Sallantaus, T., Heikkilä, R. & Tolonen, T. 2002: Spatial variation of mire surface water chemistry and vegetation in northeastern Finland. — Ann. Bot. Fennici 39: 235–251.
Surface water chemistry of two mires was studied in an area with siliceous bedrock and consequently dilute fen waters. Range of variation from moderately rich fen to ombrotrophic bog vegetation was found. Rich fen vegetation was found in Ca concentrations similar to bogs and poor fens, found in many other studies. The poor–rich gradient was related most distinctly to pH, alkalinity, conductivity and the concentrations of Mg and Na. Contrary to the vertical isolation theory of development from fen to bog, in our study the poor–rich gradient was found in an inverse vertical sequence. In the case of weakly buffered waters, downstream spatial succession of water chemistry, including accumulation of organic acidity, is suggested to play a part in the development of the poor–rich gradient. The variation of Al, Fe, Mn and S was found to form a partly independent chemical gradient, related to surface water flow from a podzolic catchment.
