The New Zealand Rain Forest: a Comparison with Tropical Rain Forest! J
The New Zealand Rain Forest: A Comparison with Tropical Rain Forest! J. W. DAWSON2 and B. V. SNEDDON2 ABSTRACT: The structure of and growth forms and habits exhibited by the New Zealand rain forest are described and compared with those of lowland tropical rain forest. Theories relating to the frequent regeneration failure of the forest dominants are outlined. The floristic affinities of the forest type are discussed and it is suggested that two main elements can be recognized-lowland tropical and montane tropical. It is concluded that the New Zealand rain forest is comparable to lowland tropical rain forest in structure and in range of special growth forms and habits. It chiefly differs in its lower stature, fewer species, and smaller leaves. The floristic similarity between the present forest and forest floras of the Tertiary in New Zealand suggest that the former may be a floristically reduced derivative of the latter. PART 1 OF THIS PAPER describes the structure The approximate number of species of seed and growth forms of the New Zealand rain plants in these forests is 240. From north to forest as exemplified by a forest in the far north. south there is an overall decrease in number of In Part 2, theories relating to the regeneration species. At about 38°S a number of species, of the dominant trees in the New Zealand rain mostly trees and shrubs, drop out or become forest generally are reviewed briefly, and their restricted to coastal sites, but it is not until about relevance to the situation in the study forest is 42°S, in the South Island, that many of the con considered. -

Tracing History
Comprehensive Summaries of Uppsala Dissertations from the Faculty of Science and Technology 911 Tracing History Phylogenetic, Taxonomic, and Biogeographic Research in the Colchicum Family BY ANNIKA VINNERSTEN ACTA UNIVERSITATIS UPSALIENSIS UPPSALA 2003 Dissertation presented at Uppsala University to be publicly examined in Lindahlsalen, EBC, Uppsala, Friday, December 12, 2003 at 10:00 for the degree of Doctor of Philosophy. The examination will be conducted in English. Abstract Vinnersten, A. 2003. Tracing History. Phylogenetic, Taxonomic and Biogeographic Research in the Colchicum Family. 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. -
Temporal Development and Regeneration Dynamics of Restored Urban Forests
Temporal Development and Regeneration Dynamics of Restored Urban Forests By Katherine de Silva A thesis submitted to the Victoria University of Wellington in fulfilment of the requirements for the degree of Masters in Ecology & Biodiversity School of Biological Sciences Faculty of Sciences Victoria University of Wellington October 2019 Supervisors: Stephen Hartley. Director of the Centre of Biodiversity & Restoration Ecology, Victoria University of Wellington Kiri Joy Wallace. Postdoctoral Fellow, Environmental Research Institute, University of Waikato. Katherine de Silva: Temporal Development and Regeneration Dynamics of Restored Urban Forests, © October 2019. 2 ABSTRACT Urban forest restoration programmes are a key tool used to initiate, re-create or accelerate the succession of forest species; improving ecosystem services, function, resilience and biodiversity. Succession is a temporal shift in species dominance driven by abiotic and biotic influences, but over decadal timescales the trajectory and success of restoration plantings in degraded urban environments can be hindered. To facilitate the successful reconstruction of forest ecosystems from scratch, an understanding of the temporal patterns in planted forest development, dynamics of seedling regeneration and dominant drivers of seedling diversity is required. Using a chronosequence approach, permanent plots were established at 44 restored urban forests aged 5 to 59 years since initial plantings took place, across five New Zealand cities between Wellington and Invercargill. Vegetation surveys were undertaken and data on micro- climate were collected. This study examined the 1) temporal dynamics of restored urban forest development and seedling regeneration and 2) dominant drivers of seedling regeneration. Data were analysed using linear regression models, breakpoint analysis and mixed-effects modelling. Early forest development (<20 years) exhibited the most changes in canopy composition and structure, forest floor dynamics, seedling community and microclimate. -

PLANT of the MONTH – LITSEA CALICARIS Plant of the Month for September Is Litsea Calicaris (Mangeao, Tangeao)
E-newsletter: No 106. September 2012 Deadline for next issue: Monday 15 October 2012 President’s message The New Zealand Plant Conservation Network will be 10 years old in April! It is hard to believe that the Network will have been in place for a decade, but so much has been achieved in that time. Around 2,000 people read this newsletter and our website use is huge. The 7,300 plant species pages, 23,000 plant images, 1.4 million plant distribution records and other website information/features provide a very valuable plant conservation resource that did not exist before the Network began. We will be celebrating this birthday with a conference, so book that May date in your diaries (see later in this newsletter). Also in this edition, are details of another major celebration (75 years this time!)— Auckland Botanical Society’s Diamond Jubilee Celebrations will feature a programme of lectures and a celebration dinner in late October (see Events for more information). This month, we have an article about a fantastic find on Banks Peninsula. Pittosporm obcordatum has been rediscovered after 170 years—well done Melissa. Two new features have been added to the website; an illustrated glossary and species pages of all of New Zealand’s marine algae, so check them out. We are calling for nominations for the NZPCN Plant Conservation Awards. I’m sure that you know of a person, group, council, school or nursery that you could nominate for the great work they are doing for plant conservation. Finally, look out for our AGM invitation in the next newsletter. -

Torus-Bearing Pit Membranes in Species of Osmanthus
IAWA Journal, Vol. 31 (2), 2010: 217–226 TORUS-BEARING PIT MEMBRANES IN SPECIES OF OSMANTHUS Roland Dute1, 5, David Rabaey2, John Allison1 and Steven Jansen3, 4 SUMMARY Torus thickenings of pit membranes are found not only in gymnosperms, but also in certain genera of dicotyledons. One such genus is Osmanthus. Wood from 17 species of Osmanthus was searched for tori. Fourteen spe- cies from three of the four sections investigated possessed these thick- enings. Ten of the species represent new records. Only the three New Caledonian species of Section Notosmanthus lacked tori. This observation in combination with other factors serves to isolate this section from the remainder of the genus. Key words: Notelaea, Osmanthus, pit membrane, torus. INTRODUCTION Osmanthus is a member of the Oleaceae (Olive Family), a moderate-sized family with circa 24 genera and 615 spp. (Stevens 2001). There are 33 natural species within the genus (Table 1; Xiang et al. 2008), and they show a tropical to temperate distribution (Bailey & Bailey 1976; Denk et al. 2001; Xiang et al. 2008). Generally, individual shrubs are found in moist forests (Hsieh et al. 1998; Chou et al. 2000; Denk et al. 2001), frequently on steep slopes (Green 1958). In some instances populations are sub- ject to monsoon conditions and hence to periods of relatively low rainfall (Yang et al. 2008; Hua 2008). Tori are thickenings of intervascular pit membranes found not only in gymnosperm, but also in angiosperm wood, including that of Osmanthus (Dute et al. 2008; Dute et al. 2010). Tori were first observed in O. fragrans, O. -

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. -
