Akçiçek, E., Vural, M., Açik, L. & Celebi, A. 2005: Notes on Campanula argaea group (Campanulaceae) in Turkey and related species. — Ann. Bot. Fennici 42: 405–410.

Campanula pamphylica (Contandr., Quézel & Pamukç.) E. Akçiçek & Vural comb. & stat. nov., previously regarded as a synonym, is shown to be a distinct species. Campanula pamphylica subsp. afyonica E. Akçiçek & Vural subsp. nova is described as a new subspecies from Anatolia, Turkey. Campanula pamphylica subsp. tokuri (A. Ocak) E. Akçiçek & Vural comb. & stat. nov. is proposed as a new combination. Diagnostic, morphological and molecular data are discussed for the taxa.

Dulamsuren, C., Hauck, M. & Mühlenberg, M. 2005: Vegetation at the taiga forest–steppe borderline in the western Khentey Mountains, northern Mongolia. — Ann. Bot. Fennici 42: 411–426.

Vegetation of an area of 500 km² in the western Khentey Mountains, northern Mongolia is phytosociologically classified with the help of 254 relevés. Twenty-one main vegetation units are described. The study area is situated at the interface between the western Siberian dark taiga, the eastern Siberian light taiga and the Mongolian-Daurian forest steppe. A small-scale pattern of these three major vegetation types was found depending on site characteristics. Dark taiga forests of Pinus sibirica, Abies sibirica, Picea obovata, and Larix sibirica grow at the most humid sites. Light taiga forests dominated by Larix sibirica and Betula platyphylla occur on relatively dry northern slopes of the lower montane belt. Sun-exposed, southern slopes of the lower montane belt are covered by montane meadow and mountain steppe. DCA ordination suggests that the distribution of vegetation types depends on water supply and altitude.

Kotiranta, H., Mukhin, V. A., Ushakova, N. & Dai, Y.-C. 2005: Polypore (Aphyllophorales, Basidiomycetes) studies in Russia. 1. South Ural. — Ann. Bot. Fennici 42: 427–451.

One hundred and thirty-nine polypore species are reported from the South Urals. One of them, Skeletocutis vulgaris (Fr.) Dai & Niemelä, is reported for the first time from Russia, and the westernmost known growth site of Phellinus sulphurascens Pilát is in the South Urals. The material consists of 829 collections and observations, and according to these, the most frequent species are Trichaptum fuscoviolaceum (Ehrenb. : Fr.) Ryvarden, followed by Fomes fomentarius (L. : Fr.) Fr., Fomitopsis pinicola (Sw. : Fr.) P. Karst., Trametes hirsuta (Wulfen : Fr.) Pilát and T. versicolor (L. : Fr.) Pilát. These constitute around 25% of all the observations, but only 3.6% of all the species. Forty-eight species were collected only once (34.5% of all species), 20 species twice (14%) and 12 species three times (8.6%). Some large and old oak (Quercus robur) dwelling species, like Buglossoporus pulvinus (Pers.) Donk, Hapalopilus croceus (Pers. : Fr.) Bondartsev & Singer, Fistulina hepatica Schaeff. : Fr. and Inonotus dryophilus (Berk.) Murrill should especially be included in the red-list of the South Urals when the listing becomes official. Another group threatened is the old-growth forest species like e.g., Amylocystis lapponica (Romell) Singer, Fomitopsis officinalis (Vill. : Fr.) Bondartsev & Singer, Junghuhnia collabens (Fr.) Ryvarden, and Rigidoporus crocatus (Pat.) Ryvarden. The collecting sites are described, the host trees listed, and descriptions and illustrations of some species given.

Türkmen, N. & Düzenli, A. 2005: Changes in floristic composition of Quercus coccifera macchia after fire in the Çukurova region (Turkey). — Ann. Bot. Fennici 42: 453–460.

We studied the floristic changes in Quercus coccifera macchia after a fire that occurred in 1986. Floristic changes in the study area were observed during the first five years and the fourteenth year after the fire. Most of the pre-fire species (98.6%) returned back within the first three years after the fire. In the fifth year, the species similarity in the burned and unburned areas was 93.8%, and the vegetation nearly reached the pre-fire physiognomy. At the end of the fourteenth year, no significant differences in terms of floristic composition and physiognomy were observed.

Xue, C.-Y., Wang, H. & Li, D.-Z. 2005: Microsporogenesis and male gametogenesis in Musella (Musaceae), a monotypic genus from Yunnan, China. — Ann. Bot. Fennici 42: 461–467.

Microsporogenesis and male gametogenesis of Musella (Musaceae), a monotypic genus endemic to Yunnan, China, are described for the first time. The anthers are tetrasporangiate. The formation of the anther wall is of the basic type. The mature anther wall consists of an epidermis, an endothecium, many middle layers and a two-layered glandular tapetum with uninucleate cells. The old anther wall consists of an epidermis with annular and helical thickenings and reduced endothecium. Successive cytokinesis follows meiosis of the microspore mother cell thence forming a T-shaped or isobilateral tetrad of microspores. Pollen grains are 2-celled. The generative cell nucleus is clavate in shape. Some special features and relationships between anther structure and pollinator type are discussed.

Rahiminejad, M. R. & Ghaemmaghami, L. 2005: Chenopodium chaldoranicum (Chenopodiaceae), a new species from Iran. — Ann. Bot. Fennici 42: 469–471.

Chenopodium chaldoranicum Rahiminejad & Ghaemmaghami sp. nova is described from Iran and illustrated in line drawings. It is compared with the morphologically close C. bryoniaefolium, C. atripliceforme and C. sosnovskyi.

Väre, H. & Kukkonen, I. 2005: Seven new species of Cyperus (Cyperaceae) section Arenarii and one new combination and typification. — Ann. Bot. Fennici 42: 473–483.

Taxonomy of species in Cyperus section Arenarii was investigated as a part of ongoing phylogenetic study. Morphological characters revealed that seven new species need to be described, three annuals, Cyperus ephemerus, C. forskalianus and C. sahelii, and four perennials, C. algeriensis, C. gubanii, C. mauretaniensis and C. pseuderemicus. Their relationships with closely related taxa are discussed and their distribution is presented. Annuals are not known previously in the section Arenarii. A new combination, C. subtilis (Kük.) Kukkonen & Väre is made. The name is typified.

Wang, F.-G., Ye, Y.-S. & Ye, H.-G. 2005: Lithocarpus yangchunensis (Fagaceae), a new species from Guangdong, China. — Ann. Bot. Fennici 42: 485–489.

Lithocarpus yangchunensis H.G. Ye & F.G. Wang (Fagaceae) is described and illustrated. It is restricted to the evergreen broad-leaved forest on Mount Hewei, Yangchun County, Guangdong Province, China. It is most similar to L. attenuatus, but differs in its long-caudate leaf blade, androgynous inflorescences, pallid cupules that enclose 3/4–4/5 of the nuts, and in the smaller nuts. A key is provided to distinguish the morphologically most similar taxa.
