Bianco Riassunto - Vengono segnalati i ritrovamenti di dieci nuove stazioni di Paludella squarrosa (Hedw.) Brid. in Trentino – Alto Adige (Italia) durante le ricerche floristiche effettuate dal 2013 al 2016 in giacimenti torbosi e zone umide di alta montagna sopra i 2000 metri di altitudine. Parole chiave: aree umide di alta montagna, depositi torbosi, Paludella squarrosa (Hedw.) Brid. Ricevuto il 04.07.2017 Accettato l’11.09.2017 Pubblicato online il 12.12.2017 Introduzione Questa briofita della famiglia delle Meesiaceae a distribuzione circumpolare artica, è da ritenersi oggi partico- larmente rara sul versante meridionale della catena alpina, un relitto di immigrazione glaciale in questi territori di alta montagna a clima continentale endoalpino con indici di continentalità molto elevati dove la permanenza al suolo del manto nevoso raggiunge mediamente circa i 170/200 gg l’anno (Giacomini 1939, Pedrotti et al. 1974). I suoi habitat elettivi sono torbiere, praterie torbose e sorgenti del piano montano e subalpino. Le Alpi rappresentano il limite meridionale dell’areale europeo che un tempo si stendeva più a sud come testimoniano ritrovamenti in blocchi di torba sulle rive del Ticino vicino a Pavia (Farneti 1899). Allo stato attuale Paludella squarrosa (Hedw.) Brid. è inquadrata come Endagered (EN) nella relativa scheda per la lista rossa della flora vascolare e crittogamica italiana (Aleffi, Tacchi 2011). Fino ad adesso era segnalata solo in 12 microstazioni (alcune delle quali in territorio lombardo sono considerate estinte) distanti tra loro e mi- nacciate sia dal turismo che da interventi di drenaggio delle acque (Aleffi, Tacchi 2011). Nel 2009 abbiamo avviato nel Trentino Alto Adige una serie d’indagini floristiche in giacimenti torbosi e zone umide di alta montagna (Goettlich 1990) comprese fra il Piano montano superiore e il Piano alpino inferiore, interessate, a suo tempo, anche da analisi polliniche (Bergamo Decarli 1988) (Fig. 1). Le motivazioni di questa scelta sono dovute al fatto che que- sti territori alpini sono stati coinvolti in ripetute oscillazioni climatiche, ancora chiaramente riconoscibili (Desio 1967). In queste zone, durante le avanzate glaciali del Tardo Olo- cene (Patzelt 1972) si sono formati notevoli depositi more- nici frontali e laterali che, in molti casi, hanno determinato la formazione di significativi giacimenti torbosi e praterie igrofile (Giacomini 1939, Marchesoni 1939). Le ricerche in questo territorio alpino, particolarmente ricco di giacimenti torbosi e zone umide, è caratterizzato a queste altitudini dalla conservazione notevole della flora vascolare e briologica dovuta soprattutto alla mancanza di inquinamento antropico, piuttosto che animale, collegate ad attività connesse con l’agricoltura e il turismo.

  • La Botanique Dans Un Contexte Local: Les Jardins De Florence À L’Époque Des Grands-Ducs (1569–1859)
    Gesnerus 74/1 (2017) 5–52 La botanique dans un contexte local: les jardins de Florence à l’époque des grands-ducs (1569–1859) René Sigrist et Sonia Zanier* Summary This article describes the social and institutional conditions of the practice of botany in early modern Florence. This practice started with the study of medical plants in hospital and university contexts, with the passion of the Medicis for gardens, and the interest of the Vallombrosian monks for cryp- togams. During the XVIIIth century, science of plants focused on classifi­ cation (morphology), pharmacology (materia medica) and vegetable phy­ siology, but included also the inventory of Tuscan flora and agronomy. These diverging aims created tensions within the nascent community of botanists, crystal­lizing around the management of gardens and the choice of classifi­ cation ­systems. After 1770, a more scientific approach of botany was made possible by the rise of experimental practices and the development of chem- istry. Yet, a true professionalization of research did not occur before the ­political ­unification of Italy, when the management of institutions and the ­recruitment of botanists were assumed by a central Ministry of education, ­instead of ­being dependent on princely favors and patrician connections. Keywords: botany, Florence, 18th century, gardens, agronomy * Cette recherche, menée pour l’essentiel à l’Institut des Sciences Sociales de l’Université de Lausanne, a été financée par le Fonds National Suisse de la recherche scientifique, subsides no 100.011_137.579 et 100.011_166.345. Les auteurs tiennent à témoigner leur gratitude envers Emma Spary pour ses suggestions bibliographiques et interprétatives, ainsi que pour ses nombreuses remarques.

  • THE IRISH RED DATA BOOK 1 Vascular Plants
    THE IRISH RED DATA BOOK 1 Vascular Plants T.G.F.Curtis & H.N. McGough Wildlife Service Ireland DUBLIN PUBLISHED BY THE STATIONERY OFFICE 1988 ISBN 0 7076 0032 4 This version of the Red Data Book was scanned from the original book. The original book is A5-format, with 168 pages. Some changes have been made as follows: NOMENCLATURE has been updated, with the name used in the 1988 edition in brackets. Irish Names and family names have also been added. STATUS: There have been three Flora Protection Orders (1980, 1987, 1999) to date. If a species is currently protected (i.e. 1999) this is stated as PROTECTED, if it was previously protected, the year(s) of the relevant orders are given. IUCN categories have been updated as follows: EN to CR, V to EN, R to V. The original (1988) rating is given in brackets thus: “CR (EN)”. This takes account of the fact that a rare plant is not necessarily threatened. The European IUCN rating was given in the original book, here it is changed to the UK IUCN category as given in the 2005 Red Data Book listing. MAPS and APPENDIX have not been reproduced here. ACKNOWLEDGEMENTS We are most grateful to the following for their help in the preparation of the Irish Red Data Book:- Christine Leon, CMC, Kew for writing the Preface to this Red Data Book and for helpful discussions on the European aspects of rare plant conservation; Edwin Wymer, who designed the cover and who, as part of his contract duties in the Wildlife Service, organised the computer applications to the data in an efficient and thorough manner.

Dipartimento di Scienze Botaniche. Università degli Studi di Cagliari v.le Sant’Ignazio da Laconi, 13. 09123 Cagliari (Italia) *Corresponding author: [email protected] Recibido el 17 de noviembre de 2007, aceptado para su publicación el 18 de febrero de 2008 Publicado "on line" en marzo de 2008 RIASSUNTO. La flora vascolare della Penisola del Sinis (Sardegna Occidentale). Viene presentato lo studio della flora vascolare della Penisola del Sinis; in totale sono state rinvenute 760 unità tassonomiche e in particolare 615 specie, 134 sottospecie, 10 varietà e 1 ibrido, riferibili a 365 generi e 87 famiglie. Le Eudicots sono risultate il gruppo sistematico dominante. Le famiglie più rappresentate sono: Poaceae (99 unità tassonomiche), Fabaceae e Asteraceae (85), Caryophyllaceae (33), Apiaceae (27) e Orchidaceae (24). I generi con maggior numero di taxa sono: Trifolium (19), Silene (14), Limonium e Medicago (13), Ophrys (12), Euphorbia e Vicia (10), Plantago (9), Allium (8) e infine Lotus, Ranunculus e Vulpia (7). Il contingente delle endemiche (54 unità tassonomiche) è risultato pari al 8,97% della componente mediterranea e mostra una dominanza degli elementi sardo-corsi (33,33%) e secondariamente sardi (24,10%), i quali unitamente raggiungono il 57,43% del totale. La flora endemica è costituita da 31 specie, 17 sottospecie e 6 varietà, inquadrati in 38 generi e 22 famiglie. Le famiglie più rappresentate sono risultate le Plumbaginaceae (10), Asteraceae e Lamiaceae (5), Fabaceae (4), Alliaceae, Euphorbiaceae e Ranunculaceae (3); il genere più ricco è risultato Limonium (10), seguito da Allium, Delphinium, Euphorbia, Scrophularia, Silene e Teucrium (2).

Matthiola species native to Turkey were collected from various locations in Anatolia, and their DNA was isolated. Revision studies performed on the basis of molecular data obtained from studies conducted in recent years have made the phylogenetic relationships and systematic positions of the taxa more apparent and reliable. Consequently, the remaining taxonomic problems among the species have been resolved through the use of DNA-based molecular analysis methods, which, unlike phenotype studies, are not affected by environmental factors. The inter-simple sequence repeat (ISSR) fingerprinting method was used in the study because its properties were considered to be more reliable and consistent than those of the randomly amplified polymorphic DNA method.
