Banksia Vincentia (Proteaceae), a New Species Known from Fourteen Plants from South-Eastern New South Wales, Australia
Phytotaxa 163 (5): 269–286 ISSN 1179-3155 (print edition) www.mapress.com/phytotaxa/ Article PHYTOTAXA Copyright © 2014 Magnolia Press ISSN 1179-3163 (online edition) http://dx.doi.org/10.11646/phytotaxa.163.5.3 Could this be Australia’s rarest Banksia? Banksia vincentia (Proteaceae), a new species known from fourteen plants from south-eastern New South Wales, Australia MARGARET L. STIMPSON1, JEREMY J. BRUHL1 & PETER H. WESTON2 1 Botany, School of Environmental and Rural Science, University of New England, Armidale NSW 2351 Australia Corresponding Author Email: [email protected] 2 National Herbarium of New South Wales, Royal Botanic Garden Sydney, Mrs Macquaries Road, Sydney, NSW 2000, Australia Abstract Possession of hooked, distinctively discolorous styles, a broadly flabellate common bract subtending each flower pair, and a lignotuber place a putative new species, Banksia sp. Jervis Bay, in the B. spinulosa complex. Phenetic analysis of individuals from all named taxa in the B. spinulosa complex, including B. sp. Jervis Bay, based on leaf, floral, seed and bract characters support recognition of this species, which is described here as Banksia vincentia M.L.Stimpson & P.H.Weston. Known only from fourteen individuals, B. vincentia is distinguished by its semi-prostrate habit, with basally prostrate, distally ascending branches from the lignotuber, and distinctive perianth colouring. Its geographical location and ecological niche also separate it from its most similar congeners. Introduction The Banksia spinulosa complex has a complicated taxonomic history (Table 1). Smith (1793) first described and named B. spinulosa Sm., and subsequent botanists named two close relatives, B. collina R.Br. and B. -

PROTEACEAE – It's All About Pollination
PROTEACEAE – it’s all about pollination …….Gail Slykhuis Illustration Philippa Hesterman, images Ellinor Campbell & Marg McDonald A predominantly southern hemisphere plant family, Proteaceae is well represented in Australia, particularly in the West, but we do have our own equally special local representatives, some of which are outlined below. A characteristic feature of many genera within this plant family is the ‘pollen presenter’, which is a fascinating mechanism by which the pollen, which would otherwise be difficult to access for potential pollination vectors such as bees, birds and nectarivorous mammals, is positioned on the extended style of the flower, facilitating cross- pollination. The stigma, which is part of the style, is not mature at this time, thus avoiding self-pollination. A hand lens would enable you to clearly see pollen presenters on the following local representatives: Banksia marginata, Grevillea infecunda, Hakea spp., Isopogon ceratophyllus and Lomatia illicifolia. It is interesting to note that both Victorian Smoke-bush Conospermum mitchellii and Prickly Geebung Persoonia juniperina, also found in our district, do not have pollen presenters. Silver Banksia Banksia marginata This shrub or small tree is readily recognisable when flowering (Feb – July) by the conspicuous yellow pollen presenters, which are an obvious floral part of the banksia flower. These flowers then slowly mature into our iconic woody banksia cones. It is interesting to observe the changes in the nature of the pollen presenters as the flower develops. The white undersides of the leathery leaves provide a clue to the choice of common name with their tip being characteristically blunt or truncate. Anglesea Grevillea Grevillea infecunda One of our endemic plants, the Anglesea Grevillea was first named in 1986 and is Anglesea Grevillea found in several locations north west of Anglesea. -

IV. On the Proteacea of Jussieu. By -Mr. Robert Brown, Lib. L.S. Read Jan. 17, 1809. THELinnean system of botany, though confessedly artificial, has not only contributed more than all others to facilitate tlie knowledge of species, but, by constantly directing the attention to those essential parts of the flower on which it is founded, has made us acquainted with more of their important modific-a t’ ions than we probably should have known, had it not been generally adopted, and has thus laid a more solid foundation for the esta- blishment of a natural arrangement, the superior importance of which no one has been inore fully impressed with than Linnzus hiinself. There are still, however, certain circumstances respccting the stamina and pistilla, which appear to iiie to havc been much less attended to than they deserve, both by Linneus and succeeding botanists. What I chiefly allude to is the state of these organs before the expansion of the flower. Tlie utility of ascertaining the internal condition of the ovarium before fecundation will liardly be called in question, now that the immortal worlis of Gxrtner and Jussieu hare demonstrated the necessity of minutely studying the fruits of plants in attempting to arrange tlicin ac- cording to tlic sum of their affinities, as in many cases the true nature of tlie ripc fruit, cspecially witli respect to the placenta- tion of the seeds, can oiily be detcrniined by this mc;~ns. Its importance is indeed expressly inculcated by many l~ot:inists, Tf’llO, 16 Mr. BROWN,on the Proteacee of Jussieu. -

Chapter 1: General Introduction and Aims
Margaret L. Stimpson Banksia spinulosa complex Chapter 1: General introduction and aims “The history of science, like the history of all human ideas, is a history of irresponsible dreams, of obstinacy, and of error. But science is one of the very few human activities perhaps the only one in which errors are systematically criticized and fairly often, in time, corrected. This is why we can say that, in science, we often learn from our mistakes, and why we can speak clearly and sensibly about making progress there.” (Popper 1963 p. 216) Proteaceae and Banksia The flowering plant family Proteaceae is predominantly distributed in the Southern Hemisphere and represents a classic Gondwanan clade, with fossils dating to c. 94 Mya, i.e., shortly after the separation of Africa from the rest of Gondwana (Guerin and Hill 2006). The family comprises about 80 genera with c. 1700 species, c.1450 of which are distributed in Australia and South Africa, which have the greatest concentrations of diversity (APG III 2009). There are also about 83 species in 8 genera in South and Central America (Prance and Plana 1998). Well known genera in the Proteaceae clade include Telopea, Protea, Banksia, Grevillea, Hakea, and Macadamia. The New South Wales floral emblem is the Waratah (Telopea speciosissima); Banksia, Grevillea, and Leucadendron are popular cut flowers, while the nuts of Macadamia integrifolia are widely grown commercially. The genus Banksia L.f. (Proteaceae subfam. Grevilleoideae) was first described on the basis of four species collected by Banks and Solander during the Cook voyage in 1770 (Thiele and Ladiges 1996; Collins et al. -
Persoonia Levis Broad-Leaved Geebung
Persoonia levis Broad-leaved Geebung Geebung is an unusual name derived from Aboriginal languages: geebung is the name used by the Dharuk in the Sydney Region, and Jibbong by the Wiradjuri1. The genus name Persoonia, to our ears, is also unusual until you find out that it is named after a Dutch mycologist (someone who studies fungi), Christiaan Hendrik Persoon. Geebungs are endemic to Australia and there are almost 100 species which, for the most part, are found in eastern Australia, and in the SW corner of Western Australia. They are mostly small trees or shrubs. This particular species, Persoonia levis, common in Sydney bushland, grows along the central and north coast of NSW, and in the SE corner of NSW and NE corner of Victoria. We are accustomed to the subtle olives, blues, greys and yellowish greens of the foliage of the Australian bush but the Broad-leaved Geebung is quite a contrast with bright, apple green foliage. The fruits, too, are unusual, round and succulent, bright green colouring to purple, very different from the dry, hard fruits of other genera in the same (Proteaceae) family, for example, Needle Bush (Hakea), Telopea (Waratah), Grevillea and Woodly Pear (Xylomelum). Geebungs are also unusual in that they have seven chromosomes that are much larger than those of other Proteaceae2. Broad-leaved Geebung has papery bark that provides some protection from bushfires. Peel back the superficial burnt bark and you will find glorious, rich crimson beneath the blackened exterior. This species also has the potential to resprout after fires, and regenerate from seed. -

Rates of Molecular Evolution and Diversification in Plants: Chloroplast
Duchene and Bromham BMC Evolutionary Biology 2013, 13:65 http://www.biomedcentral.com/1471-2148/13/65 RESEARCH ARTICLE Open Access Rates of molecular evolution and diversification in plants: chloroplast substitution rates correlate with species-richness in the Proteaceae David Duchene* and Lindell Bromham Abstract Background: Many factors have been identified as correlates of the rate of molecular evolution, such as body size and generation length. Analysis of many molecular phylogenies has also revealed correlations between substitution rates and clade size, suggesting a link between rates of molecular evolution and the process of diversification. However, it is not known whether this relationship applies to all lineages and all sequences. Here, in order to investigate how widespread this phenomenon is, we investigate patterns of substitution in chloroplast genomes of the diverse angiosperm family Proteaceae. We used DNA sequences from six chloroplast genes (6278bp alignment with 62 taxa) to test for a correlation between diversification and the rate of substitutions. Results: Using phylogenetically-independent sister pairs, we show that species-rich lineages of Proteaceae tend to have significantly higher chloroplast substitution rates, for both synonymous and non-synonymous substitutions. Conclusions: We show that the rate of molecular evolution in chloroplast genomes is correlated with net diversification rates in this large plant family. We discuss the possible causes of this relationship, including molecular evolution driving diversification, speciation increasing the rate of substitutions, or a third factor causing an indirect link between molecular and diversification rates. The link between the synonymous substitution rate and clade size is consistent with a role for the mutation rate of chloroplasts driving the speed of reproductive isolation. -
Blushing Bride FAMILY NAME: Proteaceae Species and Cultivars Of
Plant Profile Botanical Name: Serruria florida Common Name: Blushing Bride FAMILY NAME: Proteaceae Species and cultivars of special interest: Serruria florida hybrids and cvv. such as ‘Sugar ’n’ Spice’, ‘Pretty in Pink’, ‘Super Blush’, ‘Carmen’ Origin: South Africa Availability: May to October Foliage Characteristics: Stem length is 30- 60 cm. They have papery white bracts or floral leaves surrounding the flower. The sugar and spice variety has pink on the white bracts too. 5- 10 stems per bunch. Floral Characteristics: Blushing bride have feathery tufts of white to pinkish flowers. Sugar and spice variety has pink flowers. Special features and characteristics of special interest: It is thought that blushing bride got its name because of its traditional use in Africa as bridal bouquets. The species was near extinction due to being over exploited until conservation measures in the 1960s and 70s kicked in. Botanical name given in honour of James Serrurier, an 18th century professor of Botany at the Unisversity of Utrecht. Maintenance, Cultural requirements and Post Harvest Treatments: Blushing Bride is grown on large bushes in plantations across Australia. They are also grown in South Africa, Israel and the US. Handle blushing brides gently as flowers dry out quickly. They can have floral preservative. It is unknown whether it is Ethylene sensitive. When stored in cool storage keep at at 2- 4 degrees. Strip leaves from water level down. Pest and Diseases: The pedicels are vulnerable to Botrytis infection, which causes them to collapse. They do not suffer from leaf blackening like protea species do but the leaves may turn black if submerged in buckets of solution or if held for too long. -
