Taxonomic status of the Turkish members of the sections Hololeuce and Synochreati of Astragalus (Fabaceae) was analysed using variation of morphological features, seed proteins and RAPD markers. Dendrograms based on Nei's genetic distance method UPGMA were used to compare the species. The results of cluster analysis were in broad agreement with morphological classifications of these species, and they were slightly different to the arrangement of these species in Flora of Turkey. Based on RAPD, seed protein and morphological analyses, A. vuralii H. Duman & Aytaç is synonymized with A. andrasovszkyi Bornm., A. cylindraceus DC. with A. globosus Vahl, A. alindanus Boiss. with A. hirsutus Vahl, A. paecilanthus Boiss. & Heldr. with A. sibthorpianus Boiss., A. squalidus Boiss. & Noë with A. amoenus Fenzl, A. kangalicus Kit Tan & Sorger with A. fragrans Willd., and A. seydishehiricus Kit Tan & Ocakverdi, A. isparticus Kit Tan & Sorger and A. ocakverdii Kit Tan & Sorger with A. acmonotricus Fenzl. In addition to these, A. karputanus Boiss. & Noë should be treated as a subspecies of A. bicolor Lam.
Dai, Y. C., Wei, Y. L. & Wang, Z. 2004: Wood-inhabiting fungi in southern China 2. Polypores from Sichuan Province. — Ann. Bot. Fennici 41: 319–329.
250 specimens of polypores were collected in the Jiuzhaigou and Huanglong nature reserves, and the Qingcheng and Ermei Mountains in Sichuan Province of southwestern China in October 2002. Of the 132 poroid species identified, 92 are here reported for the first time from Sichuan, and 14 are new to China. Two new species, Megasporoporia rhododendri Y.C. Dai & Y.L. Wei and Oxyporus macroporus Y.C. Dai & Y.L. Wei are described and illustrated..The first-mentioned species is characterized by resupinate or rarely effused-reflexed basidiocarps with pale greyish cream pore surface, large and ellipsoid basidiospores, and by its living exclusively on Rhododendron. Oxyporus macroporus is distinguished from the other species in the genus by its extensive basidiocarps, perennial habit, large pores, and by its occurrence on coniferous hosts. A new combination, Haploporus nepalensis (T. Hattori) Y.C. Dai is proposed. A checklist of Sichuan polypores, including their substrates and collecting data, is provided, based on our own materials. The major component of the northern Sichuan polypore flora are widely distributed circumpolar, temperate and boreal species, found at higher elevations in the two nature reserves. Some East Asian and subtropical polypore species occur at lower elevations in the Qingcheng and Ermei Mountains of central and southwestern Sichuan.
Hokkanen, P. J. 2004: Bryophyte communities in herb-rich forests in Koli, eastern Finland: comparison of forest classifications based on bryophytes and vascular plants. — Ann. Bot. Fennici 41: 331–365.
The structure of the bryophyte communities of herb-rich forests has been studied relatively little in northern Europe. In this study, the bryophyte flora of herb-rich forests in eastern Finland was analysed and classified. Altogether 101 sample plots were studied. The species and sample plots were classified with TWINSPAN and ordinated with Detrended Correspondence Analysis (DCA) by using (1) bryophytes (n = 100), (2) vascular plants and bryophytes (n = 265) and (3) vascular plants (n = 165). The results indicated that bryophytes reflected different environmental factors than vascular plants. When classification was based on bryophytes, TWINSPAN clusters corresponded better to topography and stand structure than to `a priori' site types. When classification was based on vascular plants and bryophytes or on vascular plants, TWINSPAN clusters corresponded quite well to `a priori' site types. In all classifications, paludified herb-rich forests formed an own group, which might present a transition type between moist fern-rich forests and eutrophic paludified spruce forests. Bryophytes seemed to play a minor role in the classification of herb-rich forests. However, bryophytes improved the classification providing additional information of the site. The most accurate classification was obtained when both vascular plants and bryophytes were used to distinguish different vegetation types simultaneously.
Salmina, L. 2004: Factors influencing distribution of Cladium mariscus in Latvia. — Ann. Bot. Fennici 41: 367–371.
I studied factors influencing the distribution of Cladium mariscus in Latvia. Selected climate parameters, such as the mean temperature of the coldest month of the year, the mean temperature of the warmest month of the year, and the frost-free period were compared among 45 nature regions with and without C. mariscus. The study confirmed earlier findings that mainly low winter temperatures limit the distribution of C. mariscus in the northeast. However, besides low winter temperatures, also the duration of the frost-free period, historical distribution, and local factors, such as habitat availability and long-term persistence of suitable habitats influenced the distribution of C. mariscus in Latvia. Favourable climate conditions and good availability of optimal habitats for C. mariscus determined the high concentration of its occurrences in coastal regions of Latvia.

The following new species of the orchid subtribe Cyclopogoninae are described and illustrated: Pelexia ghiesbreghtii Szlach., Mytnik & Rutk., Potosia kusibabiana Szlach., Mytnik & Rutk., P. praetermissa Szlach., Mytnik & Rutk., and P. tamayoana Szlach., Mytnik & Rutk. Cyclopogon subgenus Pseudowarscea Szlach., Mytnik & Rutk. subgen. nov. is established. Keys for determination of the Mesoamerican species of Potosia are provided.
Zhao, Y.-Z. 2004: Adenophora biloba (Campanulaceae), a new species from Inner Mongolia, China. — Ann. Bot. Fennici 41: 381–382.
Adenophora biloba Y.Z. Zhao sp. nova (Campanulaceae) is described from Inner Mongolia, China. It appears most closely related to A. gmelinii. The distinguishing characters are given in a key to the two species.
