AbstractThe phylogeny of the Micarea prasina group was investigated using mitochondrial small subunit ribosomal DNA sequences from 14 taxa representing this group, four other members of the genus Micarea, and Psilolechia lucida as an outgroup. A total of 31 new mtSSU rDNA sequences were generated, including 10 from the M. micrococca complex. Bayesian, maximum parsimony (MP) and maximum likelihood (ML) methods were used to analyse the data. The results show that M. micrococca is not monophyletic and forms three strongly supported lineages: 1) M. micrococca s. str., 2) M. byssacea (Th. Fr.) Czarnota, Guzow-Krzemińska & Coppins comb. nov., and 3) a putative taxon that requires further studies. Micarea viridileprosa is a sister species to M. micrococca s. str. and the recently described M. nowakii is a sister species to M. prasina s. str. The placement of M. tomentosa within the M. prasina group is confirmed. Micarea hedlundii appears to be more closely related to the M. micrococca complex than M. prasina s. str. Descriptions, illustrations, taxonomic remarks, distribution and habitat data for M. micrococca s. str. and M. byssacea are provided. A lectotype for Biatora byssacea Hampe non Zwackh and a neotype for Catillaria prasina β [var.] byssacea are selected.

Phylogenetic study of the four sections (Aporum, Crumenata, Strongyle, and Bolbidium) of genus Dendrobium (family Orchidaceae) was conducted using molecular data. Classifications based on morphological characters have not being able to clearly divide these four sections neither do they supported their monophyly origin. Therefore, deeper and detailed analysis especially using molecular data is required to ascertain their status. Molecular evidences were used to clarify their relations either to lump them into one section or reduce them into two. The study has been carried out for the 34 species of Dendrobium using Maximum Parsimony (MP). Three nucleotide sequences data sets from two distinct genomes chloroplast DNA genes (rbcL and matK) and nuclear ribosomal DNA (ITS) were used to construct cladograms. The results that obtained from the Internal Transcribed Spacer (ITS) gene showed that the nuclear genes are reliable marker for the phylogenetic study of Dendrobium compared to chloroplast DNA with low resolution level among sections.
