Desiccation response of seed of Clianthus spp., Carmichaelia muritai, Pittosporum crassifolium and Pittosporum eugenioides A thesis presented in partial fulfilment of the requirements for the degree of Master of AgriScience in Horticulture at Massey University, Palmerston North, New Zealand Kai Yu 2015 ABSTRACT New Zealand has a rich, diverse and unique of plant life. However, the conservation status of the New Zealand indigenous vascular flora is deteriorating, with 7.6% of this flora regarded as threatened with extinction. A series of conservation approaches are required to protect species against further loss. Developing ex-situ conservation of these species requires basic information such as seed storage behaviour and seed germination requirements to be determined. However, for many species this information is missing or incomplete. The objective of this study was to determine seed storage behaviour (response to desiccation), and/or seed coat characteristics in selected New Zealand native species. Five native tree and shrub species were studied: Carmichaelia muritai, Clianthus puniceus, Clianthus maximus, Pittosporum eugenioides, and Pittosporum crassifolium. Seeds of Clianthus maximus, Clianthus puniceus, and Carmichaelia muritai were found desiccation tolerant at low moisture content (down to ~2.5%), suggesting the storage behaviour is orthodox; storage trials need to be conducted to confirm this. In contrast, the storage behaviour of Pittosporum eugenioides and Pittosporum crassifolium appears to be non-orthodox since there was some loss of viability upon drying to low moisture contents. -
SF Street Tree Species List 2019
Department of Public Works 2019 Recommended Street Tree Species List 1 Introduction The San Francisco Urban Forestry Council periodically reviews and updates this list of trees in collaboration with public and non-profit urban forestry stakeholders, including San Francisco Public Works, Bureau of Urban Forestry and Friends of the Urban Forest. The 2019 Street Tree List was approved by the Urban Forestry Council on October 22, 2019. This list is intended to be used for the public realm of streets and associated spaces and plazas that are generally under the jurisdiction of the Public Works. While the focus is on the streetscape, e.g., tree wells in the public sidewalks, the list makes accommodations for these other areas in the public realm, e.g., “Street Parks.” While this list recommends species that are known to do well in many locations in San Francisco, no tree is perfect for every potential tree planting location. This list should be used as a guideline for choosing which street tree to plant but should not be used without the help of an arborist or other tree professional. All street trees must be approved by Public Works before planting. Sections 1 and 2 of the list are focused on trees appropriate for sidewalk tree wells, and Section 3 is intended as a list of trees that have limited use cases and/or are being considered as street trees. Finally, new this year, Section 4, is intended to be a list of local native tree and arborescent shrub species that would be appropriate for those sites in the public realm that have more space than the sidewalk planting wells, for example, stairways, “Street Parks,” plazas, and sidewalk gardens, where more concrete has been extracted. -

Lombard1, G. Polizzi2*, V. Guarnaccia 2, A. Vitale 2, P.W. Crous1 Key words Abstract Calonectria spp. are important pathogens of ornamental plants in nurseries, especially in the Northern Hemisphere. They are commonly associated with a wide range of disease symptoms of roots, leaves and shoots. Calonectria During a recent survey in Tunisia, a number of Calonectria spp. were isolated from tissues of ornamental plants crown and root rot showing symptoms of leaf spot, crown and root rot. The aim of this study was to identify these Calonectria spp. using DNA phylogeny morphological and DNA sequence comparisons. Two previously undescribed Calonectria spp., C. pseudomexicana leaf spot sp. nov. and C. tunisiana sp. nov., were recognised. Calonectria mexicana and C. polizzii are newly reported for the pathogenicity African continent. Pathogenicity tests with all four Calonectria spp. showed that they are able to cause disease on systematics seedlings of Callistemon spp., Dodonaea viscosa, Metrosideros spp. and Myrtus communis.

A Selected Bibliography of Pohutukawa and Rata (1788-1999)
[Type text] Preface Stephanie Smith, an experienced librarian and Rhodes Scholar with specialist skills in the development of bibliographies, was a wonderful partner for Project Crimson in the production of this comprehensive bibliography of pohutukawa and rata. Several years ago the Project Crimson Trust recognized the need to bring together the many and diverse references to these national icons for the benefit of researchers, conservationists, students, schools and the interested public. We never imagined the project would lead to such a work of scholarship, such a labour of love. Stephanie, like others who embrace the cause rather than the job, has invested time and intellect far beyond what was ever expected, and provided us with this outstanding resource. I urge all users to read the short introduction and gain some of the flavour of Stephanie’s enthusiasm. Project Crimson would also like to acknowledge the contribution of Forest Research library staff, in particular Megan Gee, for their help and support throughout the duration of this project. Gordon Hosking Trustee, Project Crimson February 2000 INTRODUCTION: THE LIVING LIBRARY [The] world around us is a repository of information which we have only begun to delve into. Like any library, once parts are missing, it is incomplete but, unlike a library, once our books (in this instance biological species) are lost they cannot be replaced. - Catherine Wilson and David Given, Threatened Plants of New Zealand. ...right at their feet they [Wellingtonians] have one of the most wide-ranging and fascinating living textbooks of botany in the country.

New Zealand Plants in Australian Gardens Stuart Read (Updated 27/5/2018)
New Zealand Plants in Australian Gardens Stuart Read (updated 27/5/2018) 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. -
