Carnivorous Plant Newsletter of Australia
Volume 6 September, 1980. Registered as a Publication, Category B. Page 6 CPNA Page 1 EDITORS, : : : : KEN HATLEY. SUSAN HATLEY. CORRESPONDENCE ADDRESSED TO : C.P.N.A. Wandena Rd, B~allsbrook East. West Australia. 6084. Published Quarterly by C.P.N.A. Subscriptions $6-OO Annually. Back copies issued to late subscribers. ........................................................................... FROM THE EDITORS. We would like to start this issue with an apology for its late arrival to you. Unfortunately, we experienced an unexpected delay in the arrival of replacment parts for the copying equipment. The good news this issue is of course that spring is upon us again, and with it the regrowth of our dormant varieties ready to come forward and show off their beauty for yet another year. The response for articles for the newsletter is dissappointing to say the least. There is enough experienced c.p. growers in Australia capable of contributing write-ups to ensure the success of the CPNA for many years to come, but if the lack of interest continues the newsletter is doomed to failure. To put it bluntly, if you want your newsletter to continue then get behind it and give it your support. Good Growing, Editors. ........................................................................... ...........................................................................

Floral Micromorphology and Nectar Composition of the Early Evolutionary Lineage Utricularia (Subgenus Polypompholyx, Lentibulariaceae)
Protoplasma https://doi.org/10.1007/s00709-019-01401-2 ORIGINAL ARTICLE Floral micromorphology and nectar composition of the early evolutionary lineage Utricularia (subgenus Polypompholyx, Lentibulariaceae) Bartosz J. Płachno1 & Małgorzata Stpiczyńska 2 & Piotr Świątek3 & Hans Lambers4 & Gregory R. Cawthray4 & Francis J. Nge5 & Saura R. Silva6 & Vitor F. O. Miranda6 Received: 1 April 2019 /Accepted: 4 June 2019 # The Author(s) 2019 Abstract Utricularia (Lentibulariaceae) is a genus comprising around 240 species of herbaceous, carnivorous plants. Utricularia is usually viewed as an insect-pollinated genus, with the exception of a few bird-pollinated species. The bladderworts Utricularia multifida and U. tenella are interesting species because they represent an early evolutionary Utricularia branch and have some unusual morphological characters in their traps and calyx. Thus, our aims were to (i) determine whether the nectar sugar concentrations andcompositioninU. multifida and U. tenella are similar to those of other Utricularia species from the subgenera Polypompholyx and Utricularia, (ii) compare the nectary structure of U. multifida and U. tenella with those of other Utricularia species, and (iii) determine whether U. multifida and U. tenella use some of their floral trichomes as an alternative food reward for pollinators. We used light microscopy, histochemistry, and scanning and transmission electron microscopy to address those aims. The concentration and composition of nectar sugars were analysed using high-performance liquid chroma- tography. In all of the examined species, the floral nectary consisted of a spur bearing glandular trichomes. The spur produced and stored the nectar. We detected hexose-dominated (fructose + glucose) nectar in U. multifida and U. tenella as well as in U. -

Review TRENDS in Ecology & Evolution Vol.16 No.11 November 2001 623 Evolutionary ecology of carnivorous plants Aaron M. Ellison and Nicholas J. Gotelli After more than a century of being regarded as botanical oddities, carnivorous populations, elucidating how changes in fitness affect plants have emerged as model systems that are appropriate for addressing a population dynamics. As with other groups of plants, wide array of ecological and evolutionary questions. Now that reliable such as mangroves7 and alpine plants8 that exhibit molecular phylogenies are available for many carnivorous plants, they can be broad evolutionary convergence because of strong used to study convergences and divergences in ecophysiology and life-history selection in stressful habitats, detailed investigations strategies. Cost–benefit models and demographic analysis can provide insight of carnivorous plants at multiple biological scales can into the selective forces promoting carnivory. Important areas for future illustrate clearly the importance of ecological research include the assessment of the interaction between nutrient processes in determining evolutionary patterns. availability and drought tolerance among carnivorous plants, as well as measurements of spatial and temporal variability in microhabitat Phylogenetic diversity among carnivorous plants characteristics that might constrain plant growth and fitness. In addition to Phylogenetic relationships among carnivorous plants addressing evolutionary convergence, such studies must take into account have been obscured by reliance on morphological the evolutionary diversity of carnivorous plants and their wide variety of life characters1 that show a high degree of similarity and forms and habitats. Finally, carnivorous plants have suffered from historical evolutionary convergence among carnivorous taxa9 overcollection, and their habitats are vanishing rapidly. -

Flower Nectar Trichome Structure of Carnivorous Plants from the Genus Butterworts Pinguicula L
Protoplasma (2020) 257:245–259 https://doi.org/10.1007/s00709-019-01433-8 ORIGINAL ARTICLE Flower nectar trichome structure of carnivorous plants from the genus butterworts Pinguicula L. (Lentibulariaceae) Krzysztof Lustofin1 & Piotr Świątek2 & Vitor F. O. Miranda3 & Bartosz J. Płachno1 Received: 23 June 2019 /Accepted: 7 August 2019 /Published online: 19 August 2019 # The Author(s) 2019 Abstract Pinguicula (Lentibulariaceae) is a genus comprising around 96 species of herbaceous, carnivorous plants, which are extremely diverse in flower size, colour and spur length and structure as well as pollination strategy. In Pinguicula,nectarisformedinthe flower spur; however, there is a gap in the knowledge about the nectary trichome structure in this genus. Our aim was to compare the nectary trichome structure of various Pinguicula species in order to determine whether there are any differences among the species in this genus. The taxa that were sampled were Pinguicula moctezumae, P. moranensis, P. re ct if ol ia, P. emarginata and P. esseriana. We used light microscopy, histochemistry, scanning and transmission electron microscopy to address those aims. We show a conservative nectary trichome structure and spur anatomy in various Mexican Pinguicula species. The gross structural similarities between the examined species were the spur anatomy, the occurrence of papillae, the architecture of the nectary trichomes and the ultrastructure characters of the trichome cells. However, there were some differences in the spur length, the size of spur trichomes, the occurrence of starch grains in the spur parenchyma and the occurrence of cell wall ingrowths in the terminal cells of the nectary trichomes. Similar nectary capitate trichomes, as are described here, were recorded in the spurs of species from other Lentibulariaceae genera. -
Droseraceae Gland and Germination Patterns Revisited: Support for Recent Molecular Phylogenetic Studies
DROSERACEAE GLAND AND GERMINATION PATTERNS REVISITED: SUPPORT FOR RECENT MOLECULAR PHYLOGENETIC STUDIES JOHN G. CONRAN • Centre for Evolutionary Biology and Biodiversity • Environmental Biology • School of Earth and Environmental Sciences • Darling Building DP418 • The University of Adelaide • SA 5005 • Australia • [email protected] GUNTA JAUDZEMS • Department of Ecology and Evolutionary Biology • Monash University • Clayton • Vic. 3168 • Australia NEIL D. HALLAM • Department of Ecology and Evolutionary Biology • Monash University • Clayton • Vic. 3168 • Australia Keywords: Physiology: Aldrovanda, Dionaea, Drosera. Abstract Droseraceae germination and leaf gland and microgland character state patterns were re-exam- ined in the light of new molecular phylogenetic relationships. Phanerocotylar germination is basal in the family, with cryptocotylar germination having evolved at least twice; once in Aldrovanda, and again in Drosera within the Bryastrum/Ergaleium clade. Gland patterns also support major clades; with the Bryastrum clade taxa having marginal and Rorella-type glands whereas the terminal branch of the Drosera clade had marginal glands and most of the clade possessed biseriate type 3 glands. The gland and germination patterns are supported by growth habit features, suggesting that the family and the main clades within Drosera in particular have undergone major adaptive radiations for these charac- ters. Introduction Relationships between the genera and species of Droseraceae have been the subject of numerous studies, with a range of morphology-based systems produced, mainly using traditional characters such as habit, leaf-associated features and specialised propagation techniques (e.g. Planchon 1848; Diels 1906). Character evolution of traps has also been considered important in carnivorous plants (Juniper et al. 1989; Jobson & Albert 2002) and glandular patterns (Seine & Barthlott 1992, 1993; Länger et al. -
Nuytsia the Journal of the Western Australian Herbarium 30: 1–18 Published Online 28 March 2019
J.M. Percy-Bower & C.M. Parker, Updates to Western Australia’s vascular plant census for 2018 1 Nuytsia The journal of the Western Australian Herbarium 30: 1–18 Published online 28 March 2019 SHORT COMMUNICATION Updates to Western Australia’s vascular plant census for 2018 The census database at the Western Australian Herbarium (PERTH), which provides the nomenclature for the website FloraBase (Western Australian Herbarium 1998–), lists current names and recent synonymy for Western Australia’s native and naturalised vascular plants, as well as algae, bryophytes, lichens, slime moulds and some fungi. The names represented in the census are either sourced from published research or denote as yet unpublished names based on herbarium voucher specimens. We herein summarise the changes made to vascular plant names in this database during 2018. One hundred and twenty-nine taxa were newly recorded for the State, of which 24 are naturalised and 41 have been added to the Threatened and Priority Flora list for Western Australia (Smith & Jones 2018; Western Australian Herbarium 1998–) (Table 1). A total of 185 name changes were made, including the formal publication of 29 phrase-named taxa (Table 2). Plant groups for which a number of name changes were made include Hydrocotyle L. (Perkins 2018a, 2018b), Drosera L. (Lowrie 2013a, 2013b, 2014), Lepilaena Harv. (Ito et al. 2016; Macfarlane et al. 2017) and Zygophyllum L. (transferred to Roepera A.Juss. following Beier et al. 2003). Numerous phrased-named taxa in the genus Baeckea L. were formally published under an expanded circumscription of Hysterobaeckea (Nied.) Rye (Rye 2018). Table 2 also includes cases where there has been a change of taxonomic concept, misapplication, exclusion or rank change. -
Rangelands, Western Australia
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. -
How Hungry Are Carnivorous Plants?
To The Australian Flora Foundation, I would like to express my many thanks for your contribution of funds towards my PhD research. What follows is a progress report of my work to date, anticipated outcomes, research communication, and a request for the next instalment of the grant of $7875. Project background: My PhD research focuses on the nutrition and ecology of a wide range of carnivorous plants, which use specially modified leaves to attract, capture, and digest prey. I am utilising natural abundance stable isotope techniques to understand how much these plants rely on prey to gain essential nutrients, such as nitrogen. Western Australia is home to around a third of the world’s carnivorous plant species, with most of the diversity concentrated in southwest Australia and in the northern Kimberley region. Despite this, there has been very little prior research on the carnivorous plants of Western Australia, particularly in terms of their carnivorous syndrome and ecology. Research output: Over the course of the last year I have conducted fieldwork in both the Kimberley and southwest regions, and sampled several species of carnivorous plants (see Table 1), along with autotrophic reference plants and insect prey. I have transported these samples to the BayCEER Laboratory, at the University of Bayreuth, to undergo natural abundance stable isotope analysis (revealing total concentration and isotopic composition of nitrogen and carbon). This data will allow us to calculate how much of the carnivorous plants’ nutrition has originated from the digestion of captured prey, as opposed to the usual method of root uptake of soil nutrients. -

Within Genlisea, only G. tuberosa, from the Brazilian Cerrado, formed tubers, while Utricularia menziesii is the only member of the genus to form seasonally dormant tubers. We aimed to examine and compare the tuber structure of two taxonomically and phylogenetically divergent terrestrial carnivorous plants: Genlisea tuberosa and Utricularia menziesii. Additionally, we analyzed tubers of U. -
