The moss flora of Hunan Province, China, has seven genera and 17 species in the family Orthotrichaceae. Zygodon rupestris Schimp. ex Lor. is new to China. New records for Hunan include the genera Schlotheimia and Zygodon, and Macromitrium syntrichophyllum Thér. & P. de la Varde, M. ferriei Card. & Thér., Orthotrichum rupestre Schleich. ex Schwaegr., O. exiguum Sull., O. subpumilum Bartr. ex Lewinsky, and Schlotheimia grevilleana Mitt. Ulota macrocarpa Broth. is synonymized with U. crispa (Hedw.) Brid. and Macromitrium quercicola Broth. with M. ferriei. A new name Schlotheimia vittii Guo, Enroth & T.J. Kop. is proposed for S. rubiginosa (M?ll. Hal.) D.H. Vitt, hom. illeg. Eight lectotypes are selected or corrected (indexed). All species but M. ferriei are rare or very rare in Hunan. They are mostly epiphytic growing on trunks and branches of trees. They can survive in disturbed and man-made habitats, if suitable phorophytes are available. The species are described and most of them are illustrated in line drawings, and their altitudinal ranges in Hunan are presented in diagrams.

Tan, B. C., Koponen, T. & Norris, D. H. 2007: Bryophyte flora of the Huon Peninsula, Papua New Guinea. LXX. Sematophyllaceae (Musci) 1. Acanthorrhynchium, Acroporium, Clastobryophilum, Pseudopiloecium, Radulina and Trichosteleum. — Ann. Bot. Fennici 44 (Supplement A): 35–78.

The family Sematophyllaceae (Musci) of western Melanesia, mainly Papua New Guinea, is revised based on recent collections preserved at the Botanical Museum of the University of Helsinki. For western Melanesia, 18 genera and ca. 80 species of Sematophyllaceae have been reported in the literature. Of these, six genera, Acanthorrhynchium M. Fleisch. (one species), Acroporium Mitt. (16 species), Clastobryophilum M. Fleisch. (one species), Pseudopiloecium Bartr. (one species), Radulina W.R. Buck & B.C. Tan (four species), and Trichosteleum Mitt. (seven species), are treated in this paper. Trichosteleum streimannii B.C. Tan, T.J. Kop. & D.H. Norris is decribed as new for science. Three new combinations are made and 12 new synonyms proposed (indexed). Trichosteleum sematophylloides Dix. is lectotypified. Six taxa are reported as new to Papua New Guinea: Acroporium adspersum (Hampe) Broth., A. microcladon (Dozy & Molk.) B.C. Tan var. burleyii B.C. Tan, A. rigens (Dix.) Dix., A. stramineum (Reinw. & Hornsch.) M. Fleisch. var. hamulatum (M. Fleisch.) B.C. Tan, Pseudopiloecium acroporoides (Dix.) B.C. Tan, T.J. Kop. & D.H. Norris, and Radulina hamata (Dozy & Molk.) W.R. Buck & B.C. Tan var. scaberula (Mont.) B.C. Tan, T.J. Kop. & D.H. Norris. In addition, 14 taxa are reported as new to the Solomon Islands (indexed). A key to all species dealt with is provided, and illustrations provided for the new species and species not previously illustrated. The taxonomy, habitat ecology, and distribution in western Melanesia, as well as total ranges, are given for every species. A selection of previously published illustrations and an index of epithets of taxa dealt with are given.

Junikka, L. & Koek-Noorman, J. 2007: Anatomical structure of barks in Neotropical genera of Annonaceae. — Ann. Bot. Fennici 44 (Supplement A): 79–132.

Full text

The bark anatomy of 32 Neotropical genera of Annonaceae was studied. A family description based on Neotropical genera and a discussion of individual bark components are presented. Selected character states at the family and genus levels are surveyed for identification purposes. This is followed by a discussion on the taxonomical and phylogenetic relevance of bark characters according to a phylogram in preparation based on molecular characters. Although the value of many bark anatomical characters turned out to be insignificant in systematic studies of the family, some features lend support to recent phylogenetic results based on morphological and molecular data sets. The taxonomically most informative features of the bark anatomy are sclerification of phellem cells, shape of fibre groups and occurrence of crystals in bark components.
