Three New Phragmosporous Hyphomycetes on <I>Ripogonum</I MYCOTAXON Volume 111, pp. 183–196 January–March 2010 Three new phragmosporous hyphomycetes on Ripogonum from an ‘ecological island’ in New Zealand Eric H.C. McKenzie [email protected] Manaaki Whenua Landcare Research Private Bag 92170, Auckland, New Zealand Abstract — Corynespora ripogoni sp. nov., Ellisembia maungatautari sp. nov., and Solicorynespora maungatautari sp. nov., found on dead stems of Ripogonum scandens in New Zealand, are illustrated and described, and compared with related taxa. Two other hyphomycetes are recorded from New Zealand for the first time. Key words — anamorphic fungi, deuteromycetes, Ellisembia bambusicola, Sporidesmiella parva, taxonomy Introduction Maungatautari Ecological Island is a mainland conservation ‘island’ in central North Island, New Zealand. It is surrounded by 47 km of pest-proof fence, which was completed in August 2006. Except for a few isolated mice, all mammalian pests within the fence have been eradicated. The first of several threatened species of bird have been re-introduced to the area. During a visit to a small part of the reserve some dead stems of the liana, Ripogonum scandens J.R. Forst. & G. Forst. (Smilacaceae), were collected. Several phragmosporous species of hyphomycetes were identified from the stems, including three new species that are described below. Materials and methods Dead stems of Ripogonum scandens were collected from a forested area in the Maungatautari Ecological Island. The stems were incubated under humid conditions and periodically examined for sporulating microfungi. Fungal fruiting structures were removed, mounted in lactophenol or water, and examined by light microscopy. Measurements were made on material mounted in lactophenol. Dried herbarium specimens of the fungi were prepared and deposited in the New Zealand Fungal Herbarium (Herb. PDD). Some other specimens of fungi on R. scandens and R. album R. Br. (from Australia) held in Herb. PDD were also examined. All of the taxa are treated in alphabetical order by genus. 184 ...

Acta Universitatis Upsaliensis. Comprehensive Summaries of Uppsala Dissertations from the Faculty of Science and Technology 911. 33 pp. Uppsala. ISBN 91-554-5814-9 This thesis concerns the history and the intrafamilial delimitations of the plant family Colchicaceae. A phylogeny of 73 taxa representing all genera of Colchicaceae, except the monotypic Kuntheria, is presented. The molecular analysis based on three plastid regions—the rps16 intron, the atpB- rbcL intergenic spacer, and the trnL-F region—reveal the intrafamilial classification to be in need of revision. The two tribes Iphigenieae and Uvularieae are demonstrated to be paraphyletic. The well-known genus Colchicum is shown to be nested within Androcymbium, Onixotis constitutes a grade between Neodregea and Wurmbea, and Gloriosa is intermixed with species of Littonia. Two new tribes are described, Burchardieae and Tripladenieae, and the two tribes Colchiceae and Uvularieae are emended, leaving four tribes in the family. At generic level new combinations are made in Wurmbea and Gloriosa in order to render them monophyletic. The genus Androcymbium is paraphyletic in relation to Colchicum and the latter genus is therefore expanded.

Abstract Patterns of flammability across the vascular plant phylogeny, with special emphasis on the genus Dracophyllum by Xinglei Cui Fire has been part of the environment for the entire history of terrestrial plants and is a common disturbance agent in many ecosystems across the world. Fire has a significant role in influencing the structure, pattern and function of many ecosystems. Plant flammability, which is the ability of a plant to burn and sustain a flame, is an important driver of fire in terrestrial ecosystems and thus has a fundamental role in ecosystem dynamics and species evolution. However, the factors that have influenced the evolution of flammability remain unclear.

The Xanthorrhoeaceae has the largest representation with 10 genera and 99 species. Most are endemic with a few species of Lomandra and Romnalda extending to neighbouring islands. The family includes the spectacular blackboys and grass-trees. The Iridaceae is largely represented by naturalised species with 52 of the 78 species being introduced. Many of the introductions are ornamentals and several have become serious weeds. Patersonia is the largest genus with all 17 species endemic. Some of these are cultivated as ornamentals. The Dioscoreaccae is a family of economic significance, particularly in the old world tropics where some species are cultivated or collected for their tubers and bulbils. In Australia there are 5 species, one of which is a recent introduction. The endemic and native species, commonly known as yams, are traditionally eaten by the Aborigines.

Integrating data from the monocot fossil record with molecular dating techniques has the potential to help us to understand better the timing of important evolutionary events and patterns of diversification and extinction in this major and ancient clade of flowering plants. In general, the oldest well-placed fossils are used to constrain the age of nodes in molecular dating analyses. However, substantial error can be introduced if calibration fossils are not carefully evaluated and selected. Here we propose a set of 34 fossils representing 19 families and eight orders for calibrating the ages of major monocot clades. We selected these fossils because they can be placed in particular clades with confidence and they come from well-dated stratigraphic sequences.

    CURRICULUM VITAE John Godfrey Conran BORN 1960, October 13, Brisbane, Queensland DEPENDENTS Divorced, with two children CURRENT APPOINTMENT Senior Lecturer: School of Earth & Environmental Sciences, The University of Adelaide QUALIFICATIONS 1985: Ph.D. Botany, Univ. of Qld 1981: B.Sc. (Hons 1), Botany, Univ. of Qld 1980: B.Sc. Botany and Entomology, Univ. of Qld The undergraduate degree was broad-based, with subjects from the Agriculture and Science Faculties, with majors in Entomology and Botany. I completed subjects including biometrics, biochemistry, chemistry, computer science and geology, in addition to subjects offered by the Agriculture, Botany, Entomology and Zoology Departments. In Honours, I studied systematics and population variation in Banksia oblongifolia Cav. (Proteaceae). My Ph.D. studied the evolution and ecology of the net-veined petaloid monocots in the rainforests at Springbrook, SE Qld.

  • Adaptive Architecture in Rhizomatous Plants
    Adaptive architecture in rhizomatous plants A. D. BELL School of Plant Biology, L'niverszty College ofNorth Wales, Bangor, Wuler, li. K. AND P. B. TOMLINSON Huruard Uniuerrity, Haruard Forest, Petersham, Massachusetts, U.S.A. Thc. ,ir-c.tiitectuiw 01 Icw I himmatous plants has been studied in an\ morphologtral detail: a g1.e.it iniinv of those which have been studied show highly organired and repetitive hr.anc-hing pattern\. Thes;, 1)ranchiiig pattern\ ai-e largelv confined to thrre basic types: those based on a f 60' branc-hing angle, those hsed on a A 45' branching angle, and those with a predominately linrar componrnt. These vaiiou\ configui-ations must ronfer certain advantages in terms of substrate exploration and exploitation. The consistent architecture of many rhizomatous plants permits predictive graphi(- tiniulation of the branching patterns, and also permits estimates to he made ofproductlvltv in tcrni\ ol rriei-isteinistioot accumulation. As a background to this structural consideration of rhi&iatous plants, an rxtriicive bihliograptiv is presented in an appendix, covering all aspects ot rhizomatous and \toloriifei 011s gi owth.
