Brachyglottis Heeft Zomer- Tweede Tong of Lip (Zoals Aanwezig Bij Onder Andere De Bloemen Van Orchideeën) BOOMKWEKERIJ In de winter opvallend met het viltige grijze blad en in de zomer vrolijk kleurend door een overdaad aan gele ‘mar- grieten’. Brachyglottis is een plant voor twaalf maanden tuinplezier die het op een beschutte standplaats prima naar de zin heeft. Tekst: Emiel van den Berg Foto: www.visionspictures.com lle Brachyglottis-soorten behoorden vroeger tot het geslacht Senecio, een Avan de grootste plantengeslachten van het plantenrijk. Sinds de jaren zeventig van de vorige eeuw is het geslacht Brachyglottis geïn- troduceerd en zijn hier ruim 25 soorten van voorheen Senecio in ondergebracht, soorten die van oorsprong voornamelijk in Nieuw-Zee- land en Tasmanië groeien. Brachyglottis greyi De wetenschappelijke naam Brachyglottis is opgebouwd uit de Griekse woorden brachus en glossa. Het eerste woord betekent kort, het Brachyglottis heeft zomer- tweede tong of lip (zoals aanwezig bij onder andere de bloemen van orchideeën).

  • Diversity in Host Preference of Rotylenchus Spp. Y.S
    International Journal of Science, Environment ISSN 2278-3687 (O) and Technology, Vol. 7, No 5, 2018, 1786 – 1793 2277-663X (P) DIVERSITY IN HOST PREFERENCE OF ROTYLENCHUS SPP. Y.S. Rathore Principal Scientist (Retd.), Indian Institute of Pulses Research, Kanpur -208024 (U.P.) E-mail: [email protected] Abstract: Species of the genus Rotylenchus are ecto- or semi-endo parasites and feed on roots of their host plants. In the study it was found that 50% species of Rotylenchus were monophagous and mostly on plants in the clade Rosids followed by monocots, Asterids and gymnosperms. In general, Rosids and Asterids combined parasitized more than 50% host species followed by monocots. Though food preference was species specific but by and large woody plants were preferred from very primitive families like Magnoliaceae and Lauraceae to representatives of advanced families. Woody plants like pines and others made a substantial contribution in the host range of Rotylenchus. Maximum number of Rotylenchus species harboured plants in families Poaceae (monocots), Rosaceae (Rosids) and Oleaceae (Asterids) followed by Fabaceae, Fagaceae, Asteraceae and Pinaceae. It is, therefore, suggested that agricultural crops should be grown far away from wild vegetation and forest plantations. Keywords: Rotylenchus, Magnoliids, Rosids, Asterids, Gymnosperms, Host preference. INTRODUCTION Species of the genus Rotylenchus (Nematoda: Haplolaimidae) are migratory ectoparasites and browse on the surface of roots. The damage caused by them is usually limited to necrosis of penetrated cells (1). However, species with longer stylet penetrate to tissues more deeply and killing more cells and called as semi-endoparasites (2,3). The genus contains 97 nominal species which parasitize on a wide range of wild and cultivated plants worldwide (3).

  • The Island Rule and Its Application to Multiple Plant Traits
    The island rule and its application to multiple plant traits Annemieke Lona Hedi Hendriks A thesis submitted to the Victoria University of Wellington in partial fulfilment of the requirements for the degree of Master of Science in Ecology and Biodiversity Victoria University of Wellington, New Zealand 2019 ii “The larger the island of knowledge, the longer the shoreline of wonder” Ralph W. Sockman. iii iv General Abstract Aim The Island Rule refers to a continuum of body size changes where large mainland species evolve to become smaller and small species evolve to become larger on islands. Previous work focuses almost solely on animals, with virtually no previous tests of its predictions on plants. I tested for (1) reduced floral size diversity on islands, a logical corollary of the island rule and (2) evidence of the Island Rule in plant stature, leaf size and petiole length. Location Small islands surrounding New Zealand; Antipodes, Auckland, Bounty, Campbell, Chatham, Kermadec, Lord Howe, Macquarie, Norfolk, Snares, Stewart and the Three Kings. Methods I compared the morphology of 65 island endemics and their closest ‘mainland’ relative. Species pairs were identified. Differences between archipelagos located at various latitudes were also assessed. Results Floral sizes were reduced on islands relative to the ‘mainland’, consistent with predictions of the Island Rule. Plant stature, leaf size and petiole length conformed to the Island Rule, with smaller plants increasing in size, and larger plants decreasing in size. Main conclusions Results indicate that the conceptual umbrella of the Island Rule can be expanded to plants, accelerating understanding of how plant traits evolve on isolated islands.

O. Box 299, St. Louis, MO 63166–0299 U.S.A.; [email protected] Abstract A widely accessible list of known plant species is a fundamental requirement for plant conservation and has vast applications. An index of published names of liverworts and hornworts between 2009 and 2010 is provided as part of a continued effort in working toward producing a world checklist of this group. Included in the list are also names overlooked by earlier indices. The list includes 30 higher taxa, 250 species, 52 infraspecific taxa, 31 autonyms, and two fossils for 2009 and 2010. A number of taxa not covered by the earlier indices for 2000-2008 are also included. Key words: Liverworts, hornworts, index, nomenclature Introduction Under the auspices of the Early Land Plants Today project, there has been a strong community-driven effort attempting to address the critical need to synthesize the vast nomenclatural, taxonomic and global distributional data for liverworts (Marchantiophyta) and hornworts (Anthocerotophyta) (von Konrat et al. 2010a). These endeavours are critical in providing the foundation to develop a working checklist of liverworts and hornworts worldwide; the first version is projected to be published in 2012.

  • An Account of Common Broomrape Orobanche Minor (Orobanchaceae) in the British Isles
    British & Irish Botany 2(3): 223-239, 2020 An account of Common Broomrape Orobanche minor (Orobanchaceae) in the British Isles C.J. Thorogood1,2*, Fred Rumsey3 1University of Oxford Botanic Garden, Oxford, UK; 2Department of Plant Sciences, University of Oxford, Oxford, UK; 3Natural History Museum, London, UK. *Corresponding author: Chris Thorogood: [email protected] This pdf constitutes the Version of Record published on 31st August 2020 Abstract Common broomrape (Orobanche minor Sm.) is the most widespread and variable species in the British Isles and is the subject of much taxonomic confusion. Poor preservation in herbaria, coupled with the presence of cryptic host-specific races, have contributed to this. Here we review the taxonomic status of infraspecific taxa of O. minor in the British Isles, and provide a revised identification key, informed by morphology, ecology and molecular data. We describe two new varieties of O. minor s.l. that are ecologically distinct and discuss within the broader context of cryptic taxa in the subsection Minores (Beck-Mannagetta) Teryokhin in the British Isles and continental Europe. We suggest that delineating taxa objectively and reliably will be important for informing conservation priorities. Host identity and ecology, besides morphology, are essential considerations when identifying infraspecific taxa in this taxonomically challenging species. Keywords: Taxonomy; host race; parasitic plant Introduction Broomrapes (genus Orobanche L.) are renowned for being taxonomically challenging. Many of the characters useful for identification, for example stigma and corolla colour, are lost upon drying. Coupled with inadequate field notes, herbarium specimens are often determined incorrectly (Rumsey & Jury, 1991). Of the 14 species that occur in the British Isles, common broomrape (Orobanche minor Sm.) is the most widespread and variable (Figs.
