Two New Taxa of Verticordia (Myrtaceae: Chamelaucieae) from South-Western Australia
A.S.Nuytsia George 20: 309–318 & M.D. (2010)Barrett,, Two new taxa of Verticordia 309 Two new taxa of Verticordia (Myrtaceae: Chamelaucieae) from south-western Australia Alex S. George1 and Matthew D. Barrett2,3 1 ‘Four Gables’, 18 Barclay Road, Kardinya, Western Australia 6163 Email: [email protected] 2 Botanic Gardens and Parks Authority, Kings Park and Botanic Garden, Fraser Ave, West Perth, Western Australia 6005 3 School of Plant Biology, University of Western Australia, Crawley, Western Australia 6009 Email: [email protected] Abstract George, A.S. and Barrett, M.D. Two new taxa of Verticordia (Myrtaceae: Chamelaucieae) from south- western Australia. Nuytsia 20: 309–318 (2010). Verticordia mitchelliana subsp. implexior A.S.George & M.D.Barrett and Verticordia setacea A.S.George are described and discussed. Verticordia setacea belongs with V. gracilis A.S.George in section Platandra, previously a monotypic section. Introduction The genus Verticordia DC. (Myrtaceae: tribe Chamelaucieae) is a charismatic group of shrubs found mainly in south-western Australia, with several species in adjacent arid regions and three in tropical Australia (George 1991; George & Pieroni 2002). Verticordia is currently defined solely on the possession of divided calyx lobes, but the limits between Verticordia and the related genera Homoranthus A.Cunn. ex Schauer, Chamelaucium Desf. and Darwinia Rudge are difficult to define conclusively, and other characteristics such as anther morphology suggest conflicting relationships (Bentham 1867; Craven & Jones 1991; George 1991). A recent analysis using a single chloroplast gene, with limited sampling of Verticordia taxa (Ma et al. 2002), suggests that Verticordia may be polyphyletic. -
Wildflowers to Grow in Your Garden Here Is the Key to the List Large
Wildflowers to grow in your garden Here is the key to the list Trees Ground covers Shrubs Eucalypts Banksias Myrtle family Banksias Others Baeckea Other Beaufortia Calothamnus Chamelaucium Hypocalymna Kunzea Melaleuca and Callistemon Scholtzia Thryptomene Verticordia Large trees. Think very carefully before you plant them! Large trees, such as lemon scented gums or spotted gums may look great in parks - at least local councils seem to think so (we would rather see local plants). But you may regret planting them in a modern small garden. That doesn't mean there is no room for trees. There are hundreds of attractive small trees that grow very well in native gardens. Here are just a few. Small trees Eucalypts with showy flowers. Eucalytpus caesia Comes in two sub species with the one known as "silver princess" being readily available in Perth. Lovely multi- stemmed weeping tree with pendulous pink flowers and silver-bell fruits. E. torquata Small upright tree with attractive pink flowers. Very drought resistant. E. ficifolia Often called the WA Flowering gum. Ranges in size from small to quite large and in flower colour from deep red to = Corymbia ficifolia orange to pale pink. In WA subject to a serious disease - called canker. Many trees succumb when about 10 or so years old, either dying or becoming very unhealthy. E. preissiana Bell fruited mallee. Small tree (or shrub) with bright yellow flowers. E. erythrocorys Illyarrie, red cap gum or helmet nut gum. Large golden flowers in February preceded by a bright red bud cap. Tree tends to be bit floppy and to need pruning. -
Variation in Seed Production and Germination in 22 Rare and Threatened Western Australian Verticordia (Myrtaceae)
Journal of the Royal Society of Western Australia, 84:103-110, 2001 Variation in seed production and germination in 22 rare and threatened Western Australian Verticordia (Myrtaceae) A Cochrane1, K Brown2, S Cunneen3 & A Kelly4 1Threatened Flora Seed Centre, Department of Conservation and Land Management, Locked Bag 104, Bentley Delivery Centre, Perth WA 6983 2Environmental Weeds Action Network, 108 Adelaide Terrace, East Perth WA 6000 3CSIRO Centre for Mediterranean Agricultural Research, Floreat WA 6014 424 Carnarvon St, East Victoria Park WA 6100 email: [email protected] Manuscript received August 2000, accepted March 2001 Abstract This study investigates the reproductive potential of 22 rare and threatened Western Australian taxa in the genus Verticordia (Myrtaceae) over a 5-year period. Considerable inter- and intra-specific variation in both seed production and germinability was demonstrated for the majority of taxa. The seed to flower ratio, or “seed set”, ranged from 0% to 68% with an overall mean of 21% in 82 accessions representing seed from 48 populations of the 22 taxa. Percentage germination ranged from 7% to 100% with an average of 49% for 68 accessions. The precariously low annual reproductive capacity of some of the more restricted and critically endangered taxa threatens their survival and unexpected disturbance events may result in population decline or even localised extinction. Mitigation measures such as the reintroduction of plant material into new sites and the enhancement of existing populations through additional plantings may be warranted for many of Western Australia’s rare and threatened Verticordia. Keywords: Verticordia, seed production, germination Introduction prominently displayed feathery flowers are borne singly but appear as heads or spikes and are generally brightly Verticordia (family Myrtaceae, sub-family coloured, ranging from yellow to red to purple. -

Thryptomene micrantha in flower Tasmania 1 Threatened Species Section – Department of Primary Industries, Parks, Water & Environment Listing Statement for Thryptomene micrantha (ribbed heathmyrtle) IDENTIFICATION & ECOLOGY Thryptomene micrantha is a small shrub in the Myrtaceae family (Curtis & Morris 1975), known in Tasmania from the central east where it grows in near-coastal heathy woodlands on granite-derived sands. Flowering may occur from mid winter through to early summer. Beardsell et al. (1993a & b) noted that Thryptomene species tend to shed their fruit each year within 6 to 18 weeks of flowering, with at least two years ageing and weathering required before a seed’s initial dormancy is broken. Dormancy was found to be due largely to the action of the seed coat acting as a barrier to water uptake, with the surrounding fruit having a smaller inhibitory effect. -

The Vase Life of Waxflower (Chamelaucium Desf.) Is Affected by the Weight Ratio of Flowers to Stem
FOLIA HORTICULTURAE Folia Hort. 28/2 (2016): 201-207 Published by the Polish Society DOI: 10.1515/fhort-2016-0024 for Horticultural Science since 1989 ORIGINAL ARTICLE Open access http://www.foliahort.ogr.ur.krakow.pl The vase life of waxflower Chamelaucium( Desf.) is affected by the weight ratio of flowers to stem Cao D. Dung1*, Kevin Seaton2, Zora Singh3 1 Potato, Vegetable and Flower Research Center Thai phien village, Ward 12, Da Lat, Lam Dong, Vietnam 2 Department of Agriculture and Food Western Australia 3 Baron-Hay Court, South Perth, WA 6151, Australia 3 Department of Environment and Agriculture Curtin University Kent St., Bentley, Perth, WA 6102, Australia ABSTRACT The effect of flower weight on changes in the vase life of flowers and leaves of waxflowers was studied by evaluating the arranged flower weight of cultivars derived from theChamelaucium uncinatum, Chamelaucium megalopetalum and Verticordia species. Competition for water and carbohydrates between flowers and leaves influenced vase life. The removal of flowers had at least four times the effect on leaf vase life as the removal of leaves on flower vase life. Supplying exogenous sucrose to satisfy the demand for carbohydrates negated this effect, indicating that flowers depend on carbohydrates being supplied from leaves to maintain vase life. Cultivars with a greater proportion of flowers (on a weight basis) improved the vase life of flowers at the expense of the leaves. Cultivars with large flowers or many small flowers or a greater weight ratio of flowers to stem appeared to draw more carbohydrates and water from the leaves, giving them a longer vase life and decreasing the vase life of the leaves. -
Overview of the Dynamic Role of Specialty Cut Flowers in the International Cut Flower Market
horticulturae Review Overview of the Dynamic Role of Specialty Cut Flowers in the International Cut Flower Market Anastasios Darras Laboratory of Floriculture and Landscape Architecture, Department of Agriculture, University of Peloponnese, 24100 Kalamata, Greece; [email protected]; Tel.: +30-27210-45199 Abstract: The global cut flower industry has faced serious challenges over the years, but still remains an important sector of agriculture. Floriculture businesses seek new, innovative trends and niches to help increase product sales. Specialty cut flower (SCF) production has increased in the past 20 years in the US, Australia, Africa, and Europe. SCF production and sales could increase further if these new products were supported by dynamic marketing campaigns that focus on their strengths compared to the traditional cut flowers (TCF) such as roses, carnations, gerberas, and chrysanthemums. The major strength of SCF is the eco-friendly profile, which is associated to low CO2 footprints and environmental outputs. This contrasts TCF cultivation, which is associated to high energy inputs, especially at the traditional production centres (e.g., The Netherlands). It is suggested that environmental legislations, production costs, and customer demand for eco-friendly products will positively affect future SCF cultivation and sale.

Ranarivelo, 2017 1 ABSTRACT Psorospermum belongs to the tribe Vismieae (Hypericaceae). Morphologically, Psorospermum is very similar to Harungana, which also belongs to Vismieae along with another genus, Vismia. Interestingly, Harungana occurs in both Madagascar and mainland Africa, as does Psorospermum; Vismia occurs in both Africa and the New World. However, the phylogeny of the tribe and the relationship between the three genera are uncertain. -

Biodiversity Summary for NRM Regions Species List What is the summary for and where does it come from? This list has been produced by the Department of Sustainability, Environment, Water, Population and Communities (SEWPC) for the Natural Resource Management Spatial Information System. The list was produced using the AustralianAustralian Natural Natural Heritage Heritage Assessment Assessment Tool Tool (ANHAT), which analyses data from a range of plant and animal surveys and collections from across Australia to automatically generate a report for each NRM region. Data sources (Appendix 2) include national and state herbaria, museums, state governments, CSIRO, Birds Australia and a range of surveys conducted by or for DEWHA. For each family of plant and animal covered by ANHAT (Appendix 1), this document gives the number of species in the country and how many of them are found in the region. It also identifies species listed as Vulnerable, Critically Endangered, Endangered or Conservation Dependent under the EPBC Act. A biodiversity summary for this region is also available. For more information please see: www.environment.gov.au/heritage/anhat/index.html Limitations • ANHAT currently contains information on the distribution of over 30,000 Australian taxa. This includes all mammals, birds, reptiles, frogs and fish, 137 families of vascular plants (over 15,000 species) and a range of invertebrate groups. Groups notnot yet yet covered covered in inANHAT ANHAT are notnot included included in in the the list. list. • The data used come from authoritative sources, but they are not perfect. All species names have been confirmed as valid species names, but it is not possible to confirm all species locations. -
