Untangling Phylogenetic Patterns and Taxonomic Confusion in Tribe Caryophylleae (Caryophyllaceae) with Special Focus on Generic
TAXON 67 (1) • February 2018: 83–112 Madhani & al. • Phylogeny and taxonomy of Caryophylleae (Caryophyllaceae) Untangling phylogenetic patterns and taxonomic confusion in tribe Caryophylleae (Caryophyllaceae) with special focus on generic boundaries Hossein Madhani,1 Richard Rabeler,2 Atefeh Pirani,3 Bengt Oxelman,4 Guenther Heubl5 & Shahin Zarre1 1 Department of Plant Science, Center of Excellence in Phylogeny of Living Organisms, School of Biology, College of Science, University of Tehran, P.O.

This challenge is most serious in tribe Caryophylleae since the supposed genera seem to be highly artificial, and the available morphological evidence cannot effectively be used for delimitation and exact determination of taxa. The main goal of the present study was to re-assess the monophyly of the genera currently recognized in this tribe using molecular phylogenetic data. We used the sequences of nuclear ribosomal internal transcribed spacer (ITS) and the chloroplast gene rps16 for 135 and 94 accessions, respectively, representing all 16 genera currently recognized in the tribe Caryophylleae, with a rich sampling of Gypsophila as one of the most heterogeneous groups in the tribe. -

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. -

11Th Flora Malesina Symposium, Brunei Darussalm, 30 June 5 July 2019 1
11TH FLORA MALESINA SYMPOSIUM, BRUNEI DARUSSALM, 30 JUNE 5 JULY 2019 1 Welcome message The Universiti Brunei Darussalam is honoured to host the 11th International Flora Malesiana Symposium. On behalf of the organizing committee it is my pleasure to welcome you to Brunei Darussalam. The Flora Malesiana Symposium is a fantastic opportunity to engage in discussion and sharing information and experience in the field of taxonomy, ecology and conservation. This is the first time that a Flora Malesiana Symposium is organized in Brunei Darissalam and in the entire island of Borneo. At the center of the Malesian archipelago the island of Borneo magnifies the megadiversity of this region with its richness in plant and animal species. Moreover, the symposium will be an opportunity to inspire and engage the young generation of taxonomists, ecologists and conservationists who are attending it. They will be able to interact with senior researchers and get inspired with new ideas and develop further collaboration. In a phase of Biodiversity crisis, it is pivotal the understanding of plant diversity their ecology in order to have a tangible and successful result in the conservation action. I would like to thank the Vice Chancellor of UBD for supporting the symposium. In the last 6 months the organizing committee has worked very hard for making the symposium possible, to them goes my special thanks. I would like to extend my thanks to all the delegates and the keynote speakers who will make this event a memorable symposium.

Notes on Florida's Endangered and Threatened Plants 1
NOTES ON FLORIDA'S ENDANGERED AND THREATENED PLANTS 1 Nancy C. Coile2 The Regulated Plant Index is based on information provided by the Endangered Plant Advisory Council (EPAC), a group of seven individuals who represent academic, industry, and environmental interests (Dr. Loran C. Anderson, Dr. Daniel F. Austin,. Mr. Charles D. D aniel III, Mr. David M . Drylie, Jr., Ms. Eve R. Hannahs, Mr. Richard L. Moyroud, and Dr. Daniel B. Ward). Rule Chap. 5B-40, Florida Administrative Code, contains the "Regulated Plant Index" (5B-40.0055) and lists endangered, threatened, and commercially exploited plant species for Florida; defines the categories; lists instances where permits may be issued; and describes penalties for vio lations. Copies of this Rule may be obtained from Florida Department of Agriculture and Consumer Services, Division of Plant Industry, P. O. Box 147100, Gainesville, Fl 32614-7100. Amended 20 September 2000, the "Regulated Plant Index" contains 415 endangered species, 113 threatened species, and eight commercially exploited species. Descriptions of these rare species are often difficult to locate. Florida does not have a single manual covering the flora of the entire state. Long and Lakela s manual (1971) focuses on the area south of Glades County; Clewell (1985) is a guide for the Panhandle; and Wunderlin (1998) is a guide for the entire state of Florida but lacks descriptions. Small (1933) is an excellent resource, but must be used with great care since the nomenclature is outdated and frequently disputed. Clewell (1985) and Wunderlin (1998 ) are guides with keys to the flora, but lack species descriptions. Distribution maps (Wund erlin and Hansen, 200 0) are available over the Internet through the University of South Florida Herbarium [www.plantatlas.usf.edu/]. -

SuLCS und A. Sulcs (t) 226080 Riga, Stimu 18, Lettland, UdSSR. Summary Several species of Lepidoptera whose larvae feed on Gypsophila fastigiata L. are recorded from Latvia, USSR. Caryocolum petryi (Hofmann) has been found in the West, North and South-East of the country. Coleophora kyffhusana Petry, C. niveistrigella Hein. & WcK., C. burmanni Toll, Scythris emichi (Anker) and Hadena irregularis (Hufn.) are restricted to S.E. Latvia, and apparently never occur together with Caryocolum petryi. The foodplant of S. emichi was previously unk- nown, and C. burmanni had previously only been recorded on Gypsophila repens. Zusammenfassung Caryocolum petryi benanderi M. Hering wurde an mehreren Fundorten in Lettland gefunden. In SO-Lettland wurden weitere an G fastigiata gebundene Arten nachge- wiesen. Diese Gruppe umfasst folgende Arten : Coleophora kyffhusana Petry, C niveistrigella WEm. & WcK., C. burmanniToLL, Scythris emichi Anker und Hadena irregularis Hufn. Gypsophila fastigiata wird erstmals als Futterpflanze für C. burmanni und S. ew/cÄ/ beobachtet. In Lettland kann Gypsophila fastigiata L. lokal und meist nur in kleiner Anzahl in sandigen Kiefernwäldern und Kiefemschonungen beobachtet werden.

Fall-Winter 2003 [Issued August 2004] 1 VASCULAR PLANT
CROSSOSOMA 29(2), Fall-Winter 2003 [issued August 2004] 1 VASCULAR PLANT CHECKLIST FOR THE UNIVERSITY OF CALIFORNIA NATURAL RESERVE SYSTEM’S SAN JOAQUIN FRESHWATER MARSH RESERVE PETER A. BOWLER Department of Ecology and Evolutionary Biology University of California, Irvine Irvine, California 92697-2525 [email protected] MARK A. ELVIN UCI Arboretum and Herbarium (IRVC) University of California, Irvine Irvine, California 92697-1459 [email protected] ABSTRACT: The University of California Natural Reserve System’s San Joaquin Freshwater Marsh Reserve was established in 1969, and is administered by the University of California, Irvine campus. The Reserve comprises 81.75 ha (202 ac) and is located in the City of Irvine, Orange County; 75 km (45 mi) southeast of Los Angeles, 30 km (20 mi) west of the Santa Ana Mountains; 2 km (1.25 mi) upstream from Upper Newport Bay, adjacent to the Irvine campus. The elevation of the site is 2-3 m (7 to 10 ft), it receives 30 cm (12 in) of precipitation per year, and average temperatures are 29° C (86° F) in September, 4° C (40° F) minimum in January, with an annual mean of 17° C (62° F). The San Diego Creek flood control channel crosses the Reserve along its southwestern boundary. Approximately 20 ha (50 ac) of the Reserve have been restored into twelve palustrine habitats dominated by bulrushes (Schoenoplectus americanus, S. californicus and Bolboschoenus maritimus), and remainder is predominantly a cattail marsh. Nineteen acres (7.7 ha) surrounding the wetlands are a buffer zone between future development on the University’s North Campus and the Reserve.
