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. -

Euphorbia Serpens and E. Glyptosperma

GLYPTOSPERMA Culiţă SÎRBU1*, Irina ȘUȘNIA (TONE)1 1 Faculty of Agriculture, University of Agricultural Sciences and Veterinary Medicine “Ion Ionescu de la Brad”, Iaşi – Romania * Corresponding author. E-mail: [email protected] Abstract: Our recent field research and revision of some herbarium specimens led us to identify two species of Euphorbia (subgenus Chamaesyce), which we report now for the first time in the alien flora of Romania: Euphorbia serpens Kunth and E. glyptosperma Engelm. The first was collected in the city of Iaşi, north-eastern Romania, in September 2018. The second was collected, during 2005-2015, in several localities from the lower basin of the Siret river (Galați County), as well as from north-eastern Romania, near Ciurea (Iaşi County), but previously erroneously identified as “Euphorbia chamaesyce L.”. Both species, originating in the New World, are xenophytes, more or less naturalized in Europe, perhaps in full process of expansion of their secondary area. Keywords: alien plants, identification key, subgenus Chamaesyce, vascular flora. Introduction Euphorbia L. (Sp. Pl. 1: 450. 1753) is one of the most species-rich genus of flowering plants, with about 2,000 species distributed in all tropical or temperate regions of the world [PAHLEVANI & RIINA, 2011; BERRY & al. 2016]. The species of Euphorbia we further refer in the paper belong to the subgenus Chamaesyce Raf., section Anisophyllum Roeper. -

From Gymnospermae subdivision, 31 taxa belong to 14 genera of 5 families were determined. From Angiospermae subdivision, 57 taxa from 10 families belong to Monocotyl group, 356 taxa from 63 families belong to Eudicot groups, and 1 taxa from 1 family (Nymphaceae) Non-Eudicot basal group were determined. The eight of the determined 445 taxa are endemic for Turkey with the ratio of 1,8%. In addition, 151 of the taxa in the campus area are woody (trees or shrubs) and the remaining 294 taxa are annual or perennial herbaceous plants. In addition, 266 of the taxa in the campus area grow naturally, but the remaining 179 taxa are not natural (plantation or cultivation).

Introduction:- Tarnovski Heights are located in the central part of Northern Bulgaria between the rivers Vesselina and Negovanka. At the Tarnovski Heights we take the Prisovski Ridge, situated beside them. The two geographic sites are included in one protected area of the National Ecological Network of the Republic of Bulgaria, called Tarnovo Heights (with code BG0000213). This gives us reason to consider them together under the name “Tarnovski Heights”. -

Subspecies: six different subspecies of X. fastidiosa have been proposed, namely: - X. fastidiosa subsp. fastidiosa - X. fastidiosa subsp. multiplex - X. fastidiosa subsp. pauca - X. fastidiosa subsp. sandyi - X. fastidiosa subsp. tashke - X. fastidiosa subsp. morus However, of these subspecies only two, fastidiosa and multiplex, are currently officially considered as valid names by the International Society of Plant Pathology Committee on the Taxonomy of Plant Pathogenic Bacteria (ISPP- CTPPB) (Bull et al., 2012). A pathovar subdivision within X. fastidiosa has also been proposed (Hendson et al., 2001). Sequence types (STs): Multilocus sequence typing (Maiden et al., 1998) is a genetic typing methodology that is widely used to characterise X. -

This paper is the first taxonomic revision of Euphorbia subgenus Chamaesyce in Iran since the publication of Flora Iranica in 1964. We provide a key, descriptions, and illustrations for the eight species of the subgenus occurring in Iran. Euphorbia nutans is reported as a new record for the flora of Iran, E. humifusa is recognized to have two forms, pilose and glabrous; the pilose form is a first report for Flora Iranica, and E. granulata var. turcomanica is reported as a synonym of E. granulata. The following information is given for each species: accepted name, synonymy, habitat, ecology, and geographical distribution. Introduction Chamaesyce to extreme arid habitats. We recognize eight species occurring in Iran; Euphorbia is one of the five most species-rich four are indigenous annuals of dry steppes and genera of flowering plants (Frodin 2004) with deserts, and four are introduced weeds in culti- approximately 2000 species (Govaerts et al.
