Federico Selvi a Critical Checklist of the Vascular Flora of Tuscan Maremma
Federico Selvi A critical checklist of the vascular flora of Tuscan Maremma (Grosseto province, Italy) Abstract Selvi, F.: A critical checklist of the vascular flora of Tuscan Maremma (Grosseto province, Italy). — Fl. Medit. 20: 47-139. 2010. — ISSN 1120-4052. The Tuscan Maremma is a historical region of central western Italy of remarkable ecological and landscape value, with a surface of about 4.420 km2 largely corresponding to the province of Grosseto. A critical inventory of the native and naturalized vascular plant species growing in this territory is here presented, based on over twenty years of author's collections and study of relevant herbarium materials and literature. The checklist includes 2.056 species and subspecies (excluding orchid hybrids), of which, however, 49 should be excluded, 67 need confirmation and 15 have most probably desappeared during the last century. Considering the 1.925 con- firmed taxa only, this area is home of about 25% of the Italian flora though representing only 1.5% of the national surface. The main phytogeographical features in terms of life-form distri- bution, chorological types, endemic species and taxa of particular conservation relevance are presented. Species not previously recorded from Tuscany are: Anthoxanthum ovatum Lag., Cardamine amporitana Sennen & Pau, Hieracium glaucinum Jord., H. maranzae (Murr & Zahn) Prain (H. neoplatyphyllum Gottschl.), H. murorum subsp. tenuiflorum (A.-T.) Schinz & R. Keller, H. vasconicum Martrin-Donos, Onobrychis arenaria (Kit.) DC., Typha domingensis (Pers.) Steud., Vicia loiseleurii (M. Bieb) Litv. and the exotic Oenothera speciosa Nutt. Key words: Flora, Phytogeography, Taxonomy, Tuscan Maremma. Introduction Inhabited by man since millennia and cradle of the Etruscan civilization, Maremma is a historical region of central-western Italy that stretches, in its broadest sense, from south- ern Tuscany to northern Latium in the provinces of Pisa, Livorno, Grosseto and Viterbo. -

The Derivation of the Name Datisca (Datiscaceae)
Holmes, W.C. and H.J. Blizzard. 2010. The derivation of the name Datisca (Datiscaceae). Phytoneuron 2010-6: 1–2. (10 March) THE DERIVATION OF THE NAME DATISCA (DATISCACEAE) WALTER C. H OLMES AND HEATHER J. B LIZZARD Department of Biology Baylor University Waco, Texas 76798-7388 U.S.A. [email protected] ABSTRACT The name Datisca is attributed to Dioscorides in de Materia Medica , where it was cited as a Roman common name for species of Catananche (Asteraceae). Linnaeus apparently appropriated the name from Dioscorides but used it for species of a different genus and family. The derivation of the original name remains unknown. KEY WORDS : Datisca , Datiscaceae, Dioscorides, de Materia Medica . The Datiscaceae, as it will be treated in the Flora of North America, consists of a single genus of perennial herbs, Datisca , composed of two species. These are D. cannabina L. of southwest Asia from the eastern Mediterranean to the Himalayas and D. glomerata (C. Presl) Baillon of California, extreme western Nevada (near Lake Tahoe) of the southwest United States, and Baja California Norte, Mexico. Interest in the derivation of the name Datisca originated with the preparation of a treatment of Datisca glomerata for the Flora of North America North of Mexico project. The etymology of generic names is a required entry in the generic descriptions. The present manuscript is intended to supplement the brief statement on the derivation that will be presented there. Few references were found on this topic, possibly a reflection of the small size and lack of economic importance of the family. Stone (1993), in a treatment of Datisca glomerata for The Jepson Manual , merely stated “derivation unknown.” In a treatment of Datisca cannabina L. -
Germinative Response to Heat Treatments in Relation to Resprouting Ability
Journal of Ecology 2008, 96, 543–552 doi: 10.1111/j.1365-2745.2008.01359.x BurningBlackwell Publishing Ltd seeds: germinative response to heat treatments in relation to resprouting ability S. Paula and J. G. Pausas* Centro de Estudios Ambientales del Mediterráneo (CEAM), Charles R. Darwin 14, Parc Tecnològic, Paterna, València 46980, Spain Summary 1. In Mediterranean fire-prone ecosystems, plant species persist and regenerate after fire by resprouting, by recruiting new individuals from a seed bank (post-fire seeding), or by both resprouting and post-fire seeding. Since species with resprouting ability are already able to persist in fire-prone ecosystems, we hypothesize that they have been subjected to lower evolutionary pressure to acquire traits allowing or enhancing post-fire recruitment. Consequently, we predict that the germination of non-resprouters is more likely to be increased or at least unaffected by heat than the germination of resprouters. 2. To test this hypothesis we compiled published experiments carried out in Mediterranean Basin species where seeds were exposed to different heat treatments. We compared the probability of heat-tolerant germination (i.e. heated seeds had greater or equal germination than the control), the probability of heat-stimulated germination (i.e. heated seeds had greater germination than the control) and the stimulation magnitude (differences in proportion of germination of the heated seeds in relation to the untreated seeds, for heat-stimulated treatments) between resprouters and non-resprouters. 3. Non-resprouters showed higher probability of heat-tolerance, higher probability of heat- stimulation and higher stimulation magnitude even when phylogenetic relatedness was considered. Differences between life-forms and post-fire seeding ability do not explain this pattern. -

Dimorphic cypsela germination and plant growth in Synedrella nodiflora (L.) Gaertn. (Asteraceae) Souza Filho, PRM.* and Takaki, M. Departamento de Botânica, Laboratório de Fotomorfogenese de Plantas, Instituto de Biociências, Universidade Estadual Paulista “Júlio de Mesquita Filho” – UNESP, CP 199, CEP 13506-900, Rio Claro, SP, Brazil *e-mail: [email protected] Received May 4, 2010 – Accepted June 2, 2010 – Distributed May 31, 2011 (With 4 figures) Abstract Synedrella nodiflora is a weed species that has dimorphic cypselas: winged peripheral and lanceolate shaped central. The aim of this work is to describe the reproductive capability by measuring dimorphic cypselas morphology, imbibition rates and germinative patterns under temperature, light quality and water availability gradients, and compare the plant growth between two light treatments. The central cypselas were lighter, longer and its pappi were more elongated than the peripheral ones, favoring its dispersion. Neither type had deep dormancy and both of them germinated with the same pattern under the optimum conditions. Both cypselas showed higher germinability in temperatures between 25 and 30 °C, under white light and high water availability, although there are some differences between the types, mainly at dark treatments. Plants grown in direct sunlight accumulated more biomass, allowing for higher plant development and inflorescence production, although shaded light plants capitulum had a higher central: peripheral ratio than the direct sunlight treatment. S. nodiflora cypselas germinate better in unfiltered light places, although the plants are adapted to shady conditions. The species showed high germination potential over a wide range of environmental conditions, as well as fast plant development. All of these features favor distribution in environmental sites. -
AGS-Seed-List-No.62 2013-2014
WELCOME TO THE ALPINE GARDEN SOCIETY’S 62nd SEED LIST Please read through these notes and also the notes on the back of the order forms before completing the forms. The main distribution will begin in December and will continue through January. Please note that the distribution takes place from Pershore and the office will be closed for the Christmas and New Year holiday. Consequently, no orders will be made up between 20 December 2013 and 6 January 2014. The seeds offered originate from various sources and cannot be guaranteed true to name. Neither The Alpine Garden Society nor any official of the Society can be held responsible for what is supplied. Members are reminded that named cultivars and hybrids cannot be relied upon to come true, and plants raised from seed from cultivars should not be labelled with the names of those cultivars. Seeds of many species are in short supply and we can never have enough to meet all requests. If you request very rare or scarce species you may be disappointed and we advise you to spread your requests throughout a variety of seeds on the list. We do limit the allocation of rare species to try and be as fair as possible to all members, especially to those who donate the rare seed. Surplus seeds are those remaining after all applications for main distribution seeds have been met. Please see the notes on the back of the order form for further information. On-line ordering is the recommended way to order and pay for seed. There are many advantages in ordering this way, in particular a built in link to pictures of the plants on the list. -

E-mail: [email protected]. Abstract Faberia is a perennial herbaceous member of Asteraceae that is mainly distributed in central and southwestern China. Nuclear (ITS) and plastid (psbA–trnH, rbcL, matK, and trnL–F) sequences representing five Faberia species were analyzed with maximum parsimony, maximum likelihood, and Bayesian inference, all of which strongly supported the monophyly of Faberia. Faberia nanchuanensis, F. cavaleriei, and F. faberi from central China form a well-supported clade. Additionally, F. sinensis and F. thibetica from southwestern China also form a well-supported clade. Incongruence between nuclear and plastid fragments was interpreted as hybridization or limited character evolution in the plastid DNA. Faberia may have descended from hybridization between Lactucinae and Crepidinae. Besides phylogenetic results, Faberia nanchuanensis is recorded for the first time from Hunan Province, and F. -

Southern Garden History Plant Lists
Southern Plant Lists Southern Garden History Society A Joint Project With The Colonial Williamsburg Foundation September 2000 1 INTRODUCTION Plants are the major component of any garden, and it is paramount to understanding the history of gardens and gardening to know the history of plants. For those interested in the garden history of the American south, the provenance of plants in our gardens is a continuing challenge. A number of years ago the Southern Garden History Society set out to create a ‘southern plant list’ featuring the dates of introduction of plants into horticulture in the South. This proved to be a daunting task, as the date of introduction of a plant into gardens along the eastern seaboard of the Middle Atlantic States was different than the date of introduction along the Gulf Coast, or the Southern Highlands. To complicate maters, a plant native to the Mississippi River valley might be brought in to a New Orleans gardens many years before it found its way into a Virginia garden. A more logical project seemed to be to assemble a broad array plant lists, with lists from each geographic region and across the spectrum of time. The project’s purpose is to bring together in one place a base of information, a data base, if you will, that will allow those interested in old gardens to determine the plants available and popular in the different regions at certain times. This manual is the fruition of a joint undertaking between the Southern Garden History Society and the Colonial Williamsburg Foundation. In choosing lists to be included, I have been rather ruthless in expecting that the lists be specific to a place and a time.
