Bhattacharya, A. 2004: Flower visitors and fruitset of Anacardium occidentale. — Ann. Bot. Fennici 41: 385–392.
The flower visitors, pollination and fruitset of cashew (Anacardium occidentale) were studied. The investigation involved monitoring of flower visitors, assessment of floral rewards for pollinators and breeding experiments to establish the role of flower visitors on fruitset. Yield of fruits has been low due to the lack of appropriate pollinators and the possible role of ants in pollen damage. Bees, flies, butterflies, beetles and ants visited the flowers. Relative abundance of visitors coincided with nectar availability. Breeding manipulation by bagging experiments indicated that bees are efficient pollinators increasing fruitset, while ants decreased fruitset by damaging the viable pollen. Effective fruit production requires more activities of bees and management to reduce ant damages in A. occidentale.
Juslén, A. 2004: Bryophyte flora of Hunan Province, China. 7. Herbertus (Herbertaceae, Hepaticae). — Ann. Bot. Fennici 41: 393–404.
Herbertus aduncus (Dicks.) Gray subsp. aduncus and H. dicranus (Taylor ex Gottsche et al.) Trevis. are reported as new to Hunan Province of China. Descriptions and discussion on the extensive variability of the species, illustrations, and distribution maps are provided. Herbertus lonchobasis H.A. Mill. and H. wichurae Steph. are synonymized with H. dicranus. Herbertus aduncus subsp. aduncus is rare in Hunan and was not present in man-made habitats. Herbertus dicranus is rather rare, but in primeval sites it is moderately common. Herbertus aduncus subsp. aduncus is preferably epilithic, while H. dicranus grows on many substrates, which partly explains the difference in their occurrence. In Hunan, both species grow both in warm temperate and orotemperate zones which is in accordance with their global distribution.
Mráz, P. & Szelag, Z. 2004: Chromosome numbers and reproductive systems in selected species of Hieracium and Pilosella (Asteraceae) from Romania. — Ann. Bot. Fennici 41: 405–414.
Chromosome numbers are given for 17 taxa of the genus Hieracium and 4 taxa of the genus Pilosella originating from Romanian Eastern and Southern Carpathians: Hieracium alpinum (2n = 18), H. atratiforme s. lato (2n = 36), H. bifidum s. lato (2n = 27, 36), H. inuloides (2n = 27), H. jankae (2n = 27), H. lachenalii s. lato (2n = 27), H. lubricicaule (2n = 27), H. kotschyanum (2n = 27), H. magocsyanum (2n = 27), H. ostii-bucurae (2n = 27), H. praecurrens s. lato (2n = 27), H. ratezaticum (2n = 36), H. sabaudum s. lato (2n = 27), H. telekianum (2n = 27), H. tomiasae (2n = 27), H. tubulare (2n = 27), H. transylvanicum (2n = 18), Pilosella aurantiaca (2n = 36, 45), P. bauhinii (2n = 45), P. cymosa (2n = 36) and P. pavichii (2n = 18). For the first time the chromosome numbers are reported for the following taxa: H. atratiforme s. lato, H. jankae, H. lubricicaule, H. kotschyanum, H. magocsyanum, H. ostii-bucurae, H. telekianum, H. tomiasae and H. tubulare. Apomictic mode of reproduction was proved in triploids H. jankae, H. lubricicaule, H. kotschyanum, H. magocsyanum, H. ostii-bucurae, H. telekianum, H. tomiasae and H. tubulare by emasculation experiments. Diploid populations of Hieracium alpinum were confirmed in the Southern and Romanian Eastern Carpathians. Because diploid H. alpinum occurs just in the Eastern and Southern Carpathians and nowhere else, these parts of its area of distribution may be considered as glacial refugia for this species. The Skhidni Beskidi Mts. (the most western part of the Eastern Carpathians) probably represented a strong barrier of postglacial migrations of some diploid Hieracium taxa from the Eastern Carpathians towards the Western Carpathians.
Potemkin, A., Piippo, S. & Koponen, T. 2004: Bryophyte flora of Hunan Province, China. 4. Diplophyllaceae and Scapaniaceae (Hepaticae). — Ann. Bot. Fennici 41: 415–427.
Two species of Diplophyllum, D. serrulatum (Müll. Frib.) Steph. and D. taxifolium (Wahlenb.) Dumort., and three species of Scapania, S. ciliata Sande Lac., S. koponenii Potemkin, and S. ligulata Steph. are recorded and described for Hunan. A previous report of S. griffithii Schiffn. from Hunan is considered doubtful and its distribution and differentiation are discussed. Diplophyllum taxifolium is recorded for the first time for Hunan and it is very rare there. Diplophyllum serrulatum and Scapania koponenii are rare, and Scapania ciliata is moderately common. Scapania ligulata has two subspecies, subsp. ligulata and subsp. stephanii (Müll. Frib.) Potemkin, Piippo & T.J. Kop., comb. nova. Subspecies ligulata is rather rare and subsp. stephanii fairly common. Subsp. ligulata is more frequent in disturbed (more open and free of competition) than in primeval habitats, which might explain its larger size. Diplophyllum serrulatum and Scapania koponenii occur mostly in the warm-temperate zone. Scapania ciliata is mainly warm-temperate, but has some localities in the orotemperate zone. The general distribution, habitat ecology, reproduction and distinction of the taxa are discussed. Scapania ciliata is recorded as new for Vietnam.
Song, J. J., Liao, J. P., Tang, Y. J. & Chen, Z. Y. 2004: Chromosome numbers in Orchidantha (Lowiaceae) and their biogeographic and systematic implications. — Ann. Bot. Fennici 41: 429–433.
The somatic chromosome numbers of Orchidantha maxillarioides, O. insularis, O. chinensis var. chinensis, and O. chinensis var. longisepala were counted, of which O. insularis and both varieties of O. chinensis are reported for the first time. The chromosome numbers of O. maxillarioides and O. insularis are 2n = 18, apparently diploid, while that of O. chinensis is 2n = 54, and therefore hexaploid (x = 9). We discuss the biogeographic and systematic implications of the different chromosome numbers and ploidy in Orchidantha.
Väre, H. 2004: Typification of names published by the Finnish botanist Justus Montell. — Ann. Bot. Fennici 41: 435–444.
The new names (33) of plants published by Justus Montell (1869–1954) are typified. The type specimens of most of his new taxa derive from the Finnish provinces Alandia, Lapponia kittilensis or Lapponia enontekiensis. The most noteworthy names are Orchis maculatus var. kolaënsis Montell (= Dactylorhiza maculata subsp. montellii) and Carex x microstachyoides Montell (= C. dioica x heleonastes).

Cheilolejeunea trapezia (Nees) Kachroo & R.M. Schust. is the correct name for species commonly known as C. imbricata (Nees) S. Hatt. A lectotype is designated for C. inaequitexta Schiffn. ex Steph., which is synonymized with Lejeunea micholitzii Mizut.
Zielinski, J., Petrova, A. & Tan, K. 2004: Taxonomic status of the roses (Rosa) described by S.G. Dimitrov from Bulgaria. — Ann. Bot. Fennici 41: 449–451.
The original herbarium vouchers for six species of Rosa (Rosaceae) described by S. G. Dimitrov from Bulgaria are taxonomically evaluated. Two species (R. balcanica, R. orphei) are considered hybrids, four other names (R. bulgarica, R. parilica, R. pontica and R. rhodopaea) are taxonomic synonyms of widespread taxa.
Zielinski, J., Tan, K. & Tomaszewski, D. 2004: Notes on the taxonomy of Genista januensis and G. lydia (Fabaceae). — Ann. Bot. Fennici 41: 453–457.
The relationships between the closely related Mediterranean species Genista januensis Viv. and G. lydia Boiss. (Fabaceae) are discussed. The morphological differences between them are extremely subtle and they are allopatric for the greater part of their range. After extensive field and herbarium study the rank of subspecies for G. lydia is deemed appropriate.
