(Boraginaceae) species in Asiatic Russia Olga Nikiforova1* 1Central Lab of Systematics of Higher Vascular Plants, Central Siberian Botanical Garden, Novosibirsk, Russian Federation Abstract. With the help of scanning electron microscopy, morphology of stigmas and shapes of papillae were studied for 11 species (from Asiatic Russia) of genera Lithospermum L., Buglossoides Moench, Cerinthe L., Echium L., and Onosma L., belonging to tribe Lithospermeae, and two species of the genus Botriospermum Bunge of unknown taxonomical affiliation in the family Boraginaceae. It was revealed that the shapes of the stigma and papillae can be useful for clarifying relationships among the species and genera, thus complementing the data for compiling a fuller and more correct taxonomy of the family Boraginaceae. 1 Introduction The first systematic data on stigma morphology of flowering plants appeared in the works of Y. Heslop-Harrison, K. R. Shivanna [1] and Y. Heslop-Harrison [2], where they determined that stigmas of family Boraginaceae species are of the type “dry, papillate, where papillae are unicellular,” abbreviated as DPU. This means that stigmas are of the dry type without cells on the surface excreting a liquid, and that papillae have unicellular structure. Taxonomical value of stigma features was first indicated by German botanists J. Grau and A. Schwab [3] during classification of the genus Myosotis L. s. l. (tribe Myosotideae Reichenb., Boraginaceae). Subsequently, the idea of studying stigmas of Boraginaceae species has been supported by M.

In this study two phylogenies are reconstructed using parsimony and Bayesian methods. A family-level phylogeny was estimated to test the monophyly and time of divergence of the South African lineage. This analysis, based on a published ITS phylogeny and an additional ten South African taxa, showed a strongly supported South African clade sister to the campanuloids.

Phylogeny of Southern African and Australasian Wahlenbergioids (Campanulaceae) based on ITS and trnL-F sequence data: implications for a reclassification Christopher N. Cupido , Jessica M. Prebble , and William M. M. Eddie Abstract The Campanulaceae: Wahlenbergioideae currently comprises 15 genera, one of which, Wahlenbergia, is widespread over the southern continents. Southern Africa is the region with maximum wahlenbergioid diversity with 12 genera and approximately 252 species. A second center is Australasia with 38 Wahlenbergia species. This study used a broad sample of wahlenbergioid diversity from South Africa, Australia, and New Zealand to reconstruct a phylogeny based on chloroplast trnL-F and nuclear ITS sequences. Data were analyzed separately and in combination using parsimony and Bayesian methods. The results suggest that for the wahlenbergioids to be monophyletic Wahlenbergia hederacea has to be excluded and that none of the South African, Australian or New Zealand lineages are strictly monophyletic. There are five species assemblages that are in some disagreement with current classification in the family. Wahlenbergia, Prismatocarpus and Roella are shown to be non-monophyletic and implications for a reclassification are presented. Careful consideration of morphological characters is suggested before the adjustment of generic circumscriptions can be accomplished. Recent family-wide molecular phylogenetic studies have supported the view that the Campanulaceae s.s.

  • Chapter 5 Phylogeny of Poaceae Based on Matk Gene Sequences

    Chapter 5 Phylogeny of Poaceae Based on Matk Gene Sequences

    Chapter 5 Phylogeny of Poaceae Based on matK Gene Sequences 5.1 Introduction Phylogenetic reconstruction in the Poaceae began early in this century with proposed evolutionary hypotheses based on assessment of existing knowledge of grasses (e.g., Bew, 1929; Hubbard 1948; Prat, 1960; Stebbins, 1956, 1982; Clayton, 1981; Tsvelev, 1983). Imperical approaches to phylogenetic reconstruction of the Poaceae followed those initial hypotheses, starting with cladistic analyses of morphological and anatomical characters (Kellogg and Campbell, 1987; Baum, 1987; Kellogg and Watson, 1993). More recently, molecular information has provided the basis for phylogenetic hypotheses in grasses at the subfamily and tribe levels (Table 5.1). These molecular studies were based on information from chloroplast DNA (cpDNA) restriction sites and DNA sequencing of the rbcL, ndhF, rps4, 18S and 26S ribosomal DNA (rDNA), phytochrome genes, and the ITS region (Hamby and Zimmer, 1988; Doebley et al., 1990; Davis and Soreng, 1993; Cummings, King, and Kellogg, 1994; Hsiao et al., 1994; Nadot, Bajon, and Lejeune, 1994; Barker, Linder, and Harley, 1995; Clark, Zhang, and Wendel, 1995; Duvall and Morton, 1996; Liang and Hilu, 1996; Mathews and Sharrock, 1996). Although these studies have refined our concept of grass evolution at the subfamily level and, to a certain degree, at the tribal level, major disagreements and questions remain to be addressed. Outstanding discrepancies at the subfamily level include: 1) Are the pooids, bambusoids senso lato, or herbaceous bamboos the

The monotypic Taiwanese genus Mesoperla Klapálek, 1913 is redescribed on the basis of a male syntype specimen, and its affinities are re-evaluated. The single female type specimen of further two Oriental monotypic genera, Kalidasia Klapálek, 1914 and Nirvania Klapálek, 1914, are confirmed to be lost or destroyed respectively; both genera are considered as nomina dubia. The Sichuan endemic Acroneuria grahami Wu & Claassen, 1934 is redescribed on the basis of male holotype. Distinctive characters of the genus Brahmana Klapálek, 1914 consisting of five, inadequately known Oriental species are discussed. Flavoperla needhami (Klapálek, 1916) and Sinacroneuria sinica (Yang & Yang, 1998) comb. novae are suggested for an Indian species originally described in Gibosia Okamoto, 1912 and a Chinese species originally described in Acroneuria Pictet, 1841. At present, 62 species of Acroneuriinae, classified in 10 valid genera are reported from the Oriental Realm but 29 species are inadequately known. A key is presented to distinguish males of the Asian Acroneuriinae genera. Asian distribution of each genera are detailed and depicted on a map.
