However, the recent observation of the true O. migoutiana near Medea in Algeria allowed us to distinguish the Algerian and the Tunisian taxa, the latter being a priori not yet formally described. The Tunisian taxon shares some similarities with oriental taxa of the Ophrys cinereophila / Ophrys creberrima group, and is named here as a new species Ophrys pseudomigoutiana. Its phenotypic variability is illustrated by several photographs and colour plates with fresh dissected flowers. Its chorology in Tunisia is detailed and suggests that it could also be present in eastern Algeria.","PeriodicalId":7129,"journal":{"name":"Acta Botanica Gallica","volume":"162 1","pages":"255 - 261"},"PeriodicalIF":0.0,"publicationDate":"2015-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/12538078.2015.1099468","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"59706319","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study is based on an extensive data set of European literature, herbaria and web data that covers the period 1828–2012. The range of the species in Europe is disjunctive, covering the southern and western parts of the Central European Plain and the southern part of the Fennoscandian Shield. At a smaller scale, the species can also be found along some river valleys. In Central Europe many localities, particularly isolated ones in the northern part of the range, are now only historical. From the data set we determined that E. triandra may be best observed between May and October. We found that species records show a near-significant shift since 1828. Depending on the environmental conditions, individuals of the taxon develop as one of two morphs: terrestrial or aquatic. The aquatic morph is characterized by stems, internodes, lamina and petiole that are twice as long as those of the terrestrial form. Elatine triandra seeds show consistent characteristics, both in terms of morphs and populations. Our studies show that the best diagnostic features, in addition to the construction of flowers, are the size, shape and surface structure of seeds. In Central Europe, E. triandra occurs exclusively in communities classified as Isoëto-Nano-Juncetea.","PeriodicalId":7129,"journal":{"name":"Acta Botanica Gallica","volume":"162 1","pages":"325 - 337"},"PeriodicalIF":0.0,"publicationDate":"2015-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/12538078.2015.1088470","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"59706156","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A better understanding of the germination behaviour of Aegilops species is important to improve their use in breeding programmes and strengthen their in situ/ex situ conservation. In this study, we investigated the germination behaviour of nine Aegilops species, five of them not yet investigated, under two alternating and two constant temperatures. Seed germination was higher than 60% in all temperature treatments and species. Alternating temperatures promoted higher germination rates in all the species and significantly enhanced seed germination in three species (Aegilops biuncialis, Aegilops geniculata and Aegilops neglecta), in comparison with constant temperatures. One of the rarest and least productive species in the genus (Aegilops uniaristata) displayed the highest germination.

Terricolous lichens in particular are the most sensitive to threats, and have almost totally disappeared from the western Padanian Plain. This paper reports new findings of 20 terricolous lichen species, several of which are rare or poorly known in Italy or are of some phytogeographical interest because they are found at lower altitudes than their usual distribution (i.e. Cladonia coccifera, Cladonia uncialis). In addition, Cladonia humilis is new for Lombardy and two other species, Cladonia portentosa and Stereocaulon condensatum, are reported for the second time in the same region. The significance of these species is discussed with regard to their historical records from the same area and their current altitudinal distribution; they were probably much more widespread in the past, but the decline and disappearance of their habitats in lowland areas have been followed by their own disappearance in many localities. A modification of the rarity status of some of these species in the considered phytoclimatic belts, based on the new records, is proposed.","PeriodicalId":7129,"journal":{"name":"Acta Botanica Gallica","volume":"162 1","pages":"339 - 348"},"PeriodicalIF":0.0,"publicationDate":"2015-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/12538078.2015.1108867","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"59706442","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Seed number for both species was lowest in selfed fruits. Viability and germination did not show any difference in deceptive Orchis militaris treatments, but the trend was different in rewarding Platanthera bifolia. Seed number and seed abortion correlated well as did viability and germination in vitro. This shows that these two stages are controlled by different mechanisms.

Specifically on the Lebanese orchids, one book has illustrated orchids in the field with an unusual taxonomic point of view. Several Euro-Mediterranean monographs propose a conflicting taxonomy that is not always useful in identifying living specimens. Several years of exploration throughout Lebanon allowed the authors to build considerable knowledge of the orchid flora and its taxonomy. Other works made on adjacent areas completed the investigations and provided some useful indications to build taxonomic understanding and compile a preliminary checklist of Orchidaceae. Historical nomenclature was reanalysed from a modern point of view; recent critical appellations were confronted with biogeography and integrative evolutionary taxonomy, and some poorly known taxa are highlighted and their taxonomy is reinvestigated. A total of 51 species and subspecies are listed for Lebanon. Two new chorological records for Lebanon (Epipactis helleborine “subsp. praecox” nom. provis.; Ophrys alasiatica) and four new nomenclatural combinations (Androrchis × ehdenica, Epipactis helleborine subsp. turcica, Ophrys episcopalis subsp. libanotica, Serapias vomeracea subsp. levantina) are presented.
