Short Botanical Notes Typification of Galium Teres with Notes on the Galium Glaucum-Group in the Iberian Peninsula (Rubiaceae) Ann. Naturhist. Mus. Wien, B 111 277-285 Wien, März 2010 Short botanical notes E. Vitek*, W. Till**, H. Rainer*7**, B. Wallnöfer*, A. Igersheim* (eds.) This is a continuation of short taxonomical or floristic notes, which probably would not or not quickly be published. For making them availble for other researchers the curators of W and WU decided to edit this series in the Annalen des Naturhistorischen Museums. The herbarium acronyms follow the Index Herbariorum (http://sweetgum.nybg.org/ih/), nomenclatoric authors are abbreviated according to the "International Plant Names Index" (http://www.ipni.org/ - search option "authors").

Die Auffassung von K r e n d l (1979) über die Gliederung der Galium glaucum- Gruppe im Gebiet der Iberischen Halbinsel wird mit der Bearbeitung von O rtega Olivencia & Devesa (2007) in Flora Iberica verglichen. A bstract A lectotype is chosen for Galium teres M e r i n o . G. decumanum K r e n d l is stated as synonym to the earlier G. teres. The treament of the Galium glaucum- group in the Iberian Peninsula of K r e n d l (1979) is compa­ red with Flora Iberica (O livencia & Devesa 2007). Key Words: Rubiaceae, Galium glaucum, G. teres, G. decumanum; type, synonym. Introduction Kr e n d l (1979) distinguished three species in the Galium glaucum-group in the Iberian Peninsula: G. decumanum, G. pruinosum and G. murcicum. Galium teres was thought to be a synonym of G. xpomeranicum not belonging to the G. glaucum-group (E h r e n d o r - Franz Krendl, Ernst Vitek, Botanische Abteilung, Naturhistorisches Museum Wien, Burgring 7, 1010 Wien, Austria - [email protected] 2 7 8 Annalen des Naturhistorischen Museums in Wien HOB Fig. 1: Galium teres, a) lectotype [LOU], b) isotype [MA], f e r & Kr e n d l 1976).

All these species are diploid (2n = 22) in contrast to the tetraploid G. glaucum (2n = 44) in France. In Flora Iberica (O r t e g a O l iv e n c ia & D e v e s a 2007), part of these have been reduced to the level of subspecies, thus putting units of different ploidy level into one species.

Ghahremaninejad* & A A . Maassoumi** Astragalus L., a member of the legume family (Fabaceae), is the largest genus in flora of Iran (M aassoumi 1998). The mountainous region of "Assadabad" with its attractive landscape is located in Hamadan province, W. Iran. Due to the fact that with almost 3,000 species (Lock & Simpson 1991) the authors of new taxa of Astragalus frequently use the name of the type locality as suitable specific epithet, two different species of Astragalus were named A. assadabadensis. Both taxa are narrow endemics which thrive only in Hamadan province. They are mem­ bers of the Irano-Turanian floristic element: Astragalus assadabadensis M aassoumi (M aassoumi 2005, published “after 5 Aug. 2005” according to the International Plant Names Index, IPNI) and A. assadabadensis F.G hahrem . & P odlech (G hahremani ­ nejad & Podlech 2005, published “29 Jun. 2005” according to IPNI). Thus, according to the International Code of Botanical Nomenclature (M cN eill & al. 2006), the former taxon is invalid and needs to be renamed.

  • INTRODUCTION This Check List of the Plants of New Jersey Has Been
    INTRODUCTION This Check List of the Plants of New Jersey has been compiled by updating and integrating the catalogs prepared by such authors as Nathaniel Lord Britton (1881 and 1889), Witmer Stone (1911), and Norman Taylor (1915) with such other sources as recently-published local lists, field trip reports of the Torrey Botanical Society and the Philadelphia Botanical Club, the New Jersey Natural Heritage Program’s list of threatened and endangered plants, personal observations in the field and the herbarium, and observations by other competent field botanists. The Check List includes 2,758 species, a botanical diversity that is rather unexpected in a small state like New Jersey. Of these, 1,944 are plants that are (or were) native to the state - still a large number, and one that reflects New Jersey's habitat diversity. The balance are plants that have been introduced from other countries or from other parts of North America. The list could be lengthened by hundreds of species by including non-persistent garden escapes and obscure waifs and ballast plants, many of which have not been seen in New Jersey since the nineteenth century, but it would be misleading to do so. The Check List should include all the plants that are truly native to New Jersey, plus all the introduced species that are naturalized here or for which there are relatively recent records, as well as many introduced plants of very limited occurrence. But no claims are made for the absolute perfection of the list. Plant nomenclature is constantly being revised. Single old species may be split into several new species, or multiple old species may be combined into one.

Email: [email protected] Abstract The research presented in this paper had the purpose of Key words inventory and knowledge of spontaneous and subspontaneous plant species of Botanical Garden "Vasile Fati" Jibou, Salaj, Romania. Following systematic Jibou Botanical Garden, investigations undertaken in the botanical garden a large number of spontaneous flora, spontaneous taxons were found from the Romanian flora (650 species of adventive and vascular plants and 20 species of moss). Also were inventoried 38 species of subspontaneous plants, adventive plants, permanently established in Romania and 176 vascular plant floristic analysis, Romania species that have migrated from culture and multiply by themselves throughout the garden. In the garden greenhouses were found 183 subspontaneous species and weeds, both from the Romanian flora as well as tropical plants introduced by accident. Thus the total number of wild species rises to 1055, a large number compared to the occupied area. Some rare spontaneous plants and endemic to the Romanian flora (Galium abaujense, Cephalaria radiata, Crocus banaticus) were found. Cultivated species that once migrated from culture, accommodated to environmental conditions and conquered new territories; standing out is the Cyrtomium falcatum fern, once escaped from the greenhouses it continues to develop on their outer walls. Jibou Botanical Garden is the second largest exotic species can adapt and breed further without any botanical garden in Romania, after "Anastasie Fătu" care [11].

  • Reproductive Characteristics As Drivers of Alien Plant Naturalization and Invasion
    Reproductive characteristics as drivers of alien plant naturalization and invasion Dissertation submitted for the degree of Doctor of Natural Sciences presented by Mialy Harindra Razanajatovo at the Faculty of Sciences Department of Biology Date of the oral examination: 12 February 2016 First referee: Prof. Dr. Mark van Kleunen Second referee: Prof. Dr. Markus Fischer Konstanzer Online-Publikations-System (KOPS) URL: http://nbn-resolving.de/urn:nbn:de:bsz:352-0-324483 Summary Due to human activity and global movements, many plant species have been introduced to non-native regions where they experience novel abiotic and biotic conditions. Some of these alien species manage to establish reproducing naturalized populations, and some naturalized alien species subsequently become invasive. Invasion by alien plant species can negatively affect native communities and ecosystems, but what gives the alien species an advantage under novel conditions is still not clear. Therefore, identifying the drivers of invasions has become a major goal in invasion ecology. Reproduction is crucial in plant invasions, because propagule supply is required for founding new populations, population maintenance and spread in non-native regions. Baker’s Law, referring to the superior advantage of species capable of uniparental reproduction in establishing after long distance dispersal, has received major interest in explaining plant invasions. However, previous findings regarding Baker’s Law are contradicting. Moreover, there has been an increasing interest in understanding the integration of alien plant species into native plant-pollinator networks but few studies have looked at the pollination ecology of successful (naturalized and invasive) and unsuccessful (non-naturalized and non-invasive) alien plant species.

  • An Updated Checklist of the Vascular Flora of Sierra Nevada (SE Spain)
    Phytotaxa 261 (1): 001–057 ISSN 1179-3155 (print edition) http://www.mapress.com/j/pt/ PHYTOTAXA Copyright © 2016 Magnolia Press Article ISSN 1179-3163 (online edition) http://dx.doi.org/10.11646/phytotaxa.261.1.1 An updated checklist of the vascular flora of Sierra Nevada (SE Spain) JUAN LORITE Dpto. de Botánica, Universidad de Granada, ES-18071 Granada, Spain; e-mail: [email protected] Abstract To have an updated checklist available for a given area is crucial for many purposes (educational, conservation, manage- ment, etc.). In this paper, a complete and updated checklist of the vascular flora of Sierra Nevada mountain range (SE Spain), a recognized hotspot for plant diversity in the Mediterranean basin, is presented. It includes 2,353 taxa, 359 more than in the previous checklist (an increase of 15.25%). Also, data are shown on composition (in terms of families, number of hybrids, native/alien species, endemics, etc.) and threat status according to the IUCN. The result is a complete and updated checklist flora of this recognised biodiversity Mediterranean hotspot. Keywords: Baetic Mountains, Endemics, Iberian Peninsula, Plant Biodiversity Hotspot, Threatened flora, Vascular Plants Introduction The floristic inventory of a given area is the very first basis, a prerequisite, and a starting point for assessing plant conservation, management, and ecological restoration, providing information on the need for additional surveys or data collections, as well as establishing the starting point for more detailed studies (Kier et al. 2005). It aids in identifying and correctly naming species, essential resources for biodiversity estimates and biogeographic studies. Furthermore, an accurate checklist of species fulfils important social functions, since the richness value is often the simplest and the most direct way of presenting the concept of biodiversity to the society in general.

Sometimes it is even possible to distinguish Therefore, a twice larger DNA weight does not have to indicate between groups or sections, which can lead to new four sets of chromosomes. Finally, this research has also found classification of the genera. The variation in DNA weight is clues to examine further the current taxonomy of a number of also useful to analyze biodiversity, genome evolution and species or genera.
