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. -
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. -
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. -
The Vase Life of Waxflower (Chamelaucium Desf.) Is Affected by the Weight Ratio of Flowers to Stem

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. -

I have had some success in the past growhg them in containers, but even then they did not live long, probably due to lack of skill and knowledge on my part. but I wish to learn more and would appreciate your advice" Ian Budge, RSM 6, Biddle Road, Dunsborough, W.A. 6281 Ian lives on a 100 acre property, 250 Km south of Perth and 6 Km fiom the sea.. He works as a Coordinator for Parks and Gardens in the Busselton Shire and says " My training in horticulture some 26 years ago still fuels the passion I have for W.A. Native Plants but my work rarely involves verticordia. My interest in verticordia can be blamed on Elizabeth A.

Ficus Subgenus Sycomorus
BLUMEA 49: 155 –200 Published on 3 May 2004 doi: 10.3767/000651904X486278 FLORA MALESIANA PRECURSOR FOR THE TREATMENT OF MORACEAE 6: FICUS SUBGENUS SYCOMORUS C.C. BERG The Norwegian Arboretum/Botanical Institute, University of Bergen, N-5259 Hjellestad, Norway; Nationaal Herbarium Nederland, Universiteit Leiden branch, P.O. Box 9514, 2300 RA Leiden, The Netherlands SUMMARY The sections of Ficus subg. Sycomorus are described and their Malesian species listed and keyed out. Six new species are described in the subgenus: Ficus albomaculata, F. biakensis, F. boanensis, F. limosa, F. manuselensis, F. morobensis, F. remifolia, F. rubrosyce, F. scopulifera; and one new subspecies: F. botryocarpa Miq. subsp. hirtella C.C. Berg. The new combinations F. botryocarpa Miq. subsp. subalbidoramea (Elmer) C.C. Berg, F. porrecta (Corner) C.C. Berg, F. trichocerasa Diels subsp. pleioclada (Diels) C.C. Berg are also made. The following new sections and subsection are proposed: Subg. Sycomorus sect. Bosscheria (Teijsm. & de Vriese) C.C. Berg, sect. Dammaropsis (Warb.) C.C. Berg, sect. Papuasyce (Corner) C.C. Berg, and subsect. Neomorphe (King) C.C. Berg. Key words: Moraceae, Ficus subg. Sycomorus, Malesia. INTRODUCTION Ficus subg. Sycomorus (Gasp.) Miq. is described and discussed in Flora Malesia precur- sor 1 (Berg, 2003). This contribution deals with the subdivision of this subgenus, the species currently recognised for the region, the new species and subspecies discovered, and provides a key to the Malesian species. The formal subdivision is limited to sections in which a number of informal groups of presumably related species are distinguished; the ranks of series and subseries are not applied. -
Approved Conservation Advice for Syzygium Moorei (Rose Apple)
This Conservation Advice was approved by the Minister / Delegate of the Minister on: 3/07/2008. Approved Conservation Advice (s266B of the Environment Protection and Biodiversity Conservation Act 1999) Approved Conservation Advice for Syzygium moorei (Rose Apple) This Conservation Advice has been developed based on the best available information at the time this conservation advice was approved. Description Syzygium moorei, Family Myrtaceae, also known as Rose Apple, Durobby, Coolamon, Robby, or Watermelon Tree, is a tree to 40 m with a trunk diameter of up to 600 mm and a dense canopy. Leaves are thick, dark green and glossy, borne in opposite pairs and are oval to elliptical usually with a rounded tip. Bark varies in colour from red-brown to light or pinkish- grey, with soft papery scales. Flowers have masses of fluffy pink to red stamens, which are clustered on older leafless branches and often on the trunk (cauliflory). Fruit are white and fleshy with a diameter of 60 mm and a single seed (Floyd, 1989; NSW NPWS, 2002). Conservation Status Rose Apple is listed as vulnerable. This species is eligible for listing as vulnerable under the Environment Protection and Biodiversity Conservation Act 1999 (Cwlth) (EPBC Act) as, prior to the commencement of the EPBC Act, it was listed as vulnerable under Schedule 1 of the Endangered Species Protection Act 1992 (Cwlth). Rose Apple is also listed as vulnerable under the Threatened Species Conservation Act 1995 (NSW) and rare under the Nature Conservation Act 1992 (Queensland). Distribution and Habitat Rose Apple occurs in warm, protected, fertile soils in riverine and gully rainforests at low altitudes, along sections of the Richmond, Brunswick and Tweed Rivers in NSW, as well as at three sites in Upper Mudgeeraba Creek and Upper Tallebudgera Creek in south-east Queensland (Floyd, 1989).
