Patterns of flammability across the vascular plant phylogeny, with special emphasis on the genus Dracophyllum A thesis submitted in partial fulfilment of the requirements for the Degree of Doctor of philosophy at Lincoln University by Xinglei Cui Lincoln University 2020 Abstract of a thesis submitted in partial fulfilment of the requirements for the Degree of Doctor of philosophy. 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 Island Rule and Its Application to Multiple Plant Traits
    The island rule and its application to multiple plant traits Annemieke Lona Hedi Hendriks A thesis submitted to the Victoria University of Wellington in partial fulfilment of the requirements for the degree of Master of Science in Ecology and Biodiversity Victoria University of Wellington, New Zealand 2019 ii “The larger the island of knowledge, the longer the shoreline of wonder” Ralph W. Sockman. iii iv General Abstract Aim The Island Rule refers to a continuum of body size changes where large mainland species evolve to become smaller and small species evolve to become larger on islands. Previous work focuses almost solely on animals, with virtually no previous tests of its predictions on plants. I tested for (1) reduced floral size diversity on islands, a logical corollary of the island rule and (2) evidence of the Island Rule in plant stature, leaf size and petiole length. Location Small islands surrounding New Zealand; Antipodes, Auckland, Bounty, Campbell, Chatham, Kermadec, Lord Howe, Macquarie, Norfolk, Snares, Stewart and the Three Kings. Methods I compared the morphology of 65 island endemics and their closest ‘mainland’ relative. Species pairs were identified. Differences between archipelagos located at various latitudes were also assessed. Results Floral sizes were reduced on islands relative to the ‘mainland’, consistent with predictions of the Island Rule. Plant stature, leaf size and petiole length conformed to the Island Rule, with smaller plants increasing in size, and larger plants decreasing in size. Main conclusions Results indicate that the conceptual umbrella of the Island Rule can be expanded to plants, accelerating understanding of how plant traits evolve on isolated islands.

  • Vascular Plants of an Unclassified Islet, Cape Brett Peninsula, Northern New Zealand, by E.K. Cameron, P
    TANE 28,1982 VASCULAR PLANTS OF AN UNCLASSIFIED ISLET, CAPE BRETT PENINSULA, NORTHERN NEW ZEALAND by E.K. Cameron Department of Botany, University of Auckland, Private Bag, Auckland SUMMARY Seventy indigenous and 2 adventive vascular plants taxa are recorded for the "unmodified" islet. Its botanical value exceeds its small size because of the modification of the adjacent Cape Brett Peninsula and nearby islands. INTRODUCTION The islet is situated only a few metres off the northern coastline of Cape Brett Peninsula (Fig. 1). This steep beehive-shaped greywacke islet, less than two hectares in area, supports an excellent cover of indigenous vegetation compared with the adjacent goat (Copra hircus) browsed mainland. Approximately thirty minutes was spent on the islet during a four day botanical survey of Cape Brett Peninsula carried out for the Department of Lands and Survey, Auckland, in June 1980 (Cameron 1980). Time permitted only a single south-west to north-east traverse, returning to the starting point via the north-west littoral. PLANT COMMUNITIES For ease of description four plant associations (Fig. 2) are recognised although it must be remembered that these are by no means distinct as they grade into one another. Area 1: Coastal Rock. The amount of coastal rock on the islet is proportional to the degree of wave exposure and thus the north-eastern side of the islet has the greatest amount of exposed rock. Plants such as Asplenium flaccidum ssp. haurakiense, Samolus repens and the shore lobelia (Lobelia anceps) are frequently found growing in cracks and crevices. Others found here include the N.Z.

  • Vascular Plants and Vegetation of Motuopao Island, Northland, New Zealand
    VASCULAR PLANTS AND VEGETATION OF MOTUOPAO ISLAND, NORTHLAND, NEW ZEALAND by Lisa J. Forester Department of Conservation, PO Box 842, Whangarei SUMMARY Motuopao Island, off Cape Maria van Diemen in the Far North has a colourful history of settlement. Fifty-two years ago it was abandoned as a lighthouse station and the vegetation left to regenerate. This study of the vegetation of the island was done during a programme of kiore (Rattus exulans) eradication during 1988-90. The island was visited on four occasions and also flown over by helicopter. Vascular plant species are recorded and eight vegetation types are described and mapped. Regeneration is discussed as are interesting records, the island's vegetation values and weed threats. INTRODUCTION AND HISTORY Motuopao Island (Lat. 34° 28'S, Long. 172° 38' E) lies 500m off Cape Maria van Diemen at the north-western tip of the North Island. Covering 30ha, the island comprises two hills with moderately rolling inland slopes and steep basaltic seaward cliffs separated by a wide sand saddle with major valleys running to the west and east. The longest eastern valley faces the mainland and terminates in an open sand beach pounded by heavy surf. Conditions on the island are harsh and dry with a mean annual temperature of 15.5°C and a mean annual rainfall of 992mm (NZ Meteorological Service 1919-1980, Cape Reinga). Soil evaporation is probably very high as the island is windswept especially by frequent strong westerlies. Rough and unpredictable seas make access to Motuopao difficult. A colourful history of settlement is reflected in the amount of disturbance and relics of human activity on the island.

  • A New Species of Colletoecema (Rubiaceae) from Southern Cameroon with a Discussion of Relationships Among Basal Rubioideae
    BLUMEA 53: 533–547 Published on 31 December 2008 http://dx.doi.org/10.3767/000651908X607495 A NEW SPECIES OF COLLETOECEMA (RUBIACEAE) FROM SOUTHERN CAMEROON WITH A DISCUSSION OF RELATIONSHIPS AMONG BASAL RUBIOIDEAE B. SONKÉ1, S. DESSEIN2, H. TAEDOUMG1, I. GROENINCKX3 & E. ROBBRECHT2 SUMMARY Colletoecema magna, a new species from the Ngovayang Massif (southern Cameroon) is described and illustrated. A comparative morphological study illustrates the similar placentation and fruit anatomy of the novelty and Colletoecema dewevrei, the only other species of the genus. Colletoecema magna essentially differs from C. dewevrei by its sessile flowers and fruits, the corolla tube that is densely hairy above the insertion point of the stamens and the anthers that are included. Further characters that separate the novelty are its larger leaves, more condensed inflorescences, and larger fruits. Its position within Colletoecema is corroborated by atpB-rbcL and rbcL chloroplast sequences. The relationships among the basal lineages of the subfamily Rubioideae, to which Colletoecema belongs, are briefly addressed. Based on our present knowledge, a paleotropical or tropical African origin of the Rubioideae is hypothesized. Key words: Rubioideae, Rubiaceae, Colletoecema, chloroplast DNA, Ngovayang massif. INTRODUCTION Up to now, Colletoecema was known from a single species, i.e. C. dewevrei (De Wild.) E.M.A.Petit, a Guineo-Congolian endemic. The genus was established by Petit (1963) based on ‘Plectronia’ dewevrei (Rubiaceae, Vanguerieae), a species described by De Wildeman (1904). Petit (1963) demonstrated that this species does not belong to the Canthium complex and described a new genus, i.e. Colletoecema. He also showed that the original position in Vanguerieae could not be upheld.

  • New Zealand Plants in Australian Gardens Stuart Read
    New Zealand Plants in Australian Gardens Stuart Read Abstract: (11.6.2013): Raised in a large New Zealand garden full of native trees, plant lover Stuart Read was perhaps hard-wired to notice kiwi plants in Australian gardens. Over time he's pieced together a pattern of waves of fashion in their planting and popularity, reflecting scientific and horticultural expansionism, commercial and familial networks and connections across the Tasman. Stuart will examine a range of NZ plants found in old and younger Australian gardens, try to tease out some of the means by which they got here and why they remain popular. No cabbage, This constellation of asterisks Slaps and rustles Its tough tatters In the brisk breeze; Whispers of times past And ancient histories (Barbara Mitcalfe’s poem, ‘Ti Kouka’ (cabbage tree) catches well the distinctive skyline profile of this ubiquitous New Zealand export (in Simpson, 2000, 213) Introduction / overview New Zealand gardens have been introduced to and cultivated in Australian gardens from early in their ‘discovery’, trade and exchanges between the two colonies. Australian and other explorers, botanists, nurserymen, New Zealand settlers and others searched New Zealand’s coasts and bush, bringing plants into cultivation, export and commerce from early in the settlement’s colonization. New Zealand plants have had their ‘vogue’ periods, including as: A) - Economic plants (various timbers, kauri gum for shellacs and jewellery; flax for fibre, rope, cloth; greens for scurvy; poroporo for the contraceptive ‘the pill’); B) - Exotic ornamental imports into Australian gardens and beyond to English and European conservatories (and some warmer, southern) gardens and parks; C) - Depicted or carved as subjects of botanical and other artworks, commercial commodities.

    View metadata, citation and similar papers at core.ac.uk brought to you by CORE provided by Lincoln University Research Archive “Lincoln University campus: a guide to some of the shrubs currently growing there” Roy Edwards Department of Agricultural Science Lincoln University May 2009 The purpose of this book is to illustrate some of the range of shrubs currently grown on the Lincoln University campus. There are also a few trees that were not covered in the 1st book. This should be read in conjunction with its companion - “Lincoln University campus - a guide to some of the trees currently growing there” (April 2008). This also is a first draft and hopefully there will be further editions that will add species to address some of the obvious gaps.
