DELFORGE, P. & DELFORGE-ONCKELINX, C. - Contribution to the knowledge of the Orchids of the Methana peninsula and the island of Poros (Saronic Gulf, Attiki, Greece). A presen- tation of the geology, the geomorphology, the climate, the vegetation, the human impact over the landscape of the Methana peninsula and the island of Poros is provided. A review of the past and present studies and research about their orchids is presented. It appears that 20 orchids species were known for Methana peninsula before 2014 (Table 1), and prob- ably none for Poros. Research on Methana in March and April 2014 has revealed 36 orchid species for the peninsula, bringing their number up to 38 (Table 1). Research on Poros has revealed 10 species for the island (Table 2). First mentions are made in the Methana penin- sula for Cephalanthera longifolia, Dactylorhiza romana, Herorchis boryi, H. picta var. skorpilii, Ophrys cephaloniensis, O. cerastes, O. cinereophila, O. crassicornis, O. hellenica, O. leucadica, O. mammosa, O. mycenensis, O. phryganae, O. punctulata, O. spruneri, O. taigetica, O. ulyssea, Orchis provincialis, O. quadripunctata, Paludorchis palustris var. elegans, Serapias parviflora, and Vermeulenia papilionacea var. aegaea. After careful examination of “critical” plants as well as photographies, published or not, it appears that old or recent mentions of orchids, made for Methana, are questionable or erroneous. Mentions of Anacamptis morio, Ophrys cornuta, O. fusca, O. lutea, O. oestrifera subsp. schlechteriana, O. tenthredinifera, and Orchis anatolica probably concern, respectively, Herorchis picta var. skorpilii, Ophrys cerastes, O. punctulata, O. sicula var. transadriatica, O. mycenensis, O. villosa, and Orchis quadripunctata. The species found on Poros in 2014 are Anacamptis pyramidalis var. brachystachys, Ophrys cinereophila, O. hellenica, O. leptomera, O. leucadica, O. mammosa, O. sicula var. transadriatica, O. villosa, Serapias bergonii, and Vermeulenia papilionacea var. aegaea. A list of 36 species and 3 hybrids, and 41 distribution maps, based on previous locali- zable records, published or not, and on the presence in March and April 2014 in × 51 UTMwgs84 squares of 1 km 1 km, are provided as well as a list of 93 sites prospected.

  • Phylogenetic Placement of the Enigmatic Orchid Genera Thaia and Tangtsinia: Evidence from Molecular and Morphological Characters
    TAXON 61 (1) • February 2012: 45–54 Xiang & al. • Phylogenetic placement of Thaia and Tangtsinia Phylogenetic placement of the enigmatic orchid genera Thaia and Tangtsinia: Evidence from molecular and morphological characters Xiao-Guo Xiang,1 De-Zhu Li,2 Wei-Tao Jin,1 Hai-Lang Zhou,1 Jian-Wu Li3 & Xiao-Hua Jin1 1 Herbarium & State Key Laboratory of Systematic and Evolutionary Botany, Institute of Botany, Chinese Academy of Sciences, Beijing 100093, P.R.

China 3 Xishuangbanna Tropical Botanical Garden, Chinese Academy of Sciences, Menglun Township, Mengla County, Yunnan province 666303, P.R. China Author for correspondence: Xiao-Hua Jin, [email protected] Abstract The phylogenetic position of two enigmatic Asian orchid genera, Thaia and Tangtsinia, were inferred from molecular data and morphological evidence. An analysis of combined plastid data (rbcL + matK + psaB) using Bayesian and parsimony methods revealed that Thaia is a sister group to the higher epidendroids, and tribe Neottieae is polyphyletic unless Thaia is removed. Morphological evidence, such as plicate leaves and corms, the structure of the gynostemium and the micromorphol- ogy of pollinia, also indicates that Thaia should be excluded from Neottieae. Thaieae, a new tribe, is therefore tentatively established. Using Bayesian and parsimony methods, analyses of combined plastid and nuclear datasets (rbcL, matK, psaB, trnL-F, ITS, Xdh) confirmed that the monotypic genus Tangtsinia was nested within and is synonymous with the genus Cepha- lanthera, in which an apical stigma has evolved independently at least twice.

  • Orchid Observations in Croatia in 2016
    1 Orchid observations in Croatia in 201 6 Frank Verhart, Maastricht , the Nether lands [email protected] I ntroduction and general remarks As in 2014/2015 I visited Croatia for observation of wild orchids. In 2016 I went to Croatia twice. From 14 april until 1 May I was on the Southern Dalmatian peninsula Pelješac and from 11 until 30 June I explored the area between the Plitvice National Park and the city of Karlovac in the counties Lika - Senj and Karlovac. As always I did observations o f wild orchids on locations often not registered in the Flora Croatica Database (FCD) , a project of the Department of Botany of the University of Zagreb . At Pelješac interesting observations I did include those of Cephalanthera damasonium and Orchis ustula ta , as both have not been reported before from the peninsula. I found Epipactis microphylla , Ophrys bombyliflora and Serapias ionica , all of which have been recorded very rarely from Pelješac in the past. The visit to the inland of Croatia in June also yie lded observations of Epipactis microphylla , however by far the most frequently seen orchid species was Orchis ustulata of which a great many locations were recorded, many of those new. In the next chapters I present the results of these visits. Distrib ution maps The distribution maps in this article were taken from the Flora Croatica Database (FCD, Nikolić 2016 ) . The units of distribution are based on MTB, a current standard for mapping flora in Croatia. MTB is an abbreviation of the German “ “Meßtischblätter” , which means topographic map and corresponds with 10 degrees longitude and 6 degrees latitude grid.

Recently discovered fossils document their existence for at least 15 Ma. The last common ancestor of all orchids has been estimated to exist about 80 Ma ago (Ramirez et al. 2007, Gustafsson et al. 2010). Orchids are cosmopolitan, distributed on all continents and a great variety of habitats, ranging from deserts and swamps to arctic regions. Two large groups can be distinguished: Epiphytic and epilithic orchids attach themselves with aerial roots to trees or stones, mostly halfway between the ground and the upper canopy where they absorb water through the velamen of their roots.

Die Abgrenzung von Gattungen oder anderen höheren Taxa erfolgt nach modernen Ansätzen weitestgehend auf der Rekonstruktion der Stammesgeschichte (Stamm- baum-Theorie), mit Hilfe von großen Daten-Matrizen. Wenngleich aufgrund des Fortschritts in der DNS-Sequenzierungstechnik immer mehr Merkmale in der DNS identiiziert werden, ist es mindestens genauso wichtig, die Anzahl der analysierten Planzen zu erhöhen, um genaue Zuordnungen zu erschließen. Die größere Vielfalt mathematischer Methoden zur Erstellung von Stammbäumen führt nicht gleichzeitig zu verbesserten Methoden zur Beurteilung der Stabilität der Zweige innerhalb der Stammbäume. Ein weiterer kontraproduktiver Trend ist die wachsende Tendenz, diverse Datengruppen mit einzelnen Matrizen zu verquicken, die besser einzeln analysiert würden, um festzustellen, ob sie ähnliche Schlussfolgerungen bezüglich der Verwandtschaftsverhältnisse liefern. Ein Stammbaum zur Abgrenzung höherer Taxa muss nicht so robust sein, wie ein Stammbaum, aus dem man Details des Evo- lutionsmusters

  • Phylogeny, Character Evolution and the Systematics of Psilochilus (Triphoreae)
    THE PRIMITIVE EPIDENDROIDEAE (ORCHIDACEAE): PHYLOGENY, CHARACTER EVOLUTION AND THE SYSTEMATICS OF PSILOCHILUS (TRIPHOREAE) A Dissertation Presented in Partial Fulfillment of the Requirements for The Degree Doctor of Philosophy in the Graduate School of the Ohio State University By Erik Paul Rothacker, M.Sc. ***** The Ohio State University 2007 Doctoral Dissertation Committee: Approved by Dr. John V. Freudenstein, Adviser Dr. John Wenzel ________________________________ Dr. Andrea Wolfe Adviser Evolution, Ecology and Organismal Biology Graduate Program COPYRIGHT ERIK PAUL ROTHACKER 2007 ABSTRACT Considering the significance of the basal Epidendroideae in understanding patterns of morphological evolution within the subfamily, it is surprising that no fully resolved hypothesis of historical relationships has been presented for these orchids. This is the first study to improve both taxon and character sampling. The phylogenetic study of the basal Epidendroideae consisted of two components, molecular and morphological. A molecular phylogeny using three loci representing each of the plant genomes including gap characters is presented for the basal Epidendroideae. Here we find Neottieae sister to Palmorchis at the base of the Epidendroideae, followed by Triphoreae. Tropidieae and Sobralieae form a clade, however the relationship between these, Nervilieae and the advanced Epidendroids has not been resolved. A morphological matrix of 40 taxa and 30 characters was constructed and a phylogenetic analysis was performed. The results support many of the traditional views of tribal composition, but do not fully resolve relationships among many of the tribes. A robust hypothesis of relationships is presented based on the results of a total evidence analysis using three molecular loci, gap characters and morphology. Palmorchis is placed at the base of the tree, sister to Neottieae, followed successively by Triphoreae sister to Epipogium, then Sobralieae.

  • Folegandros Island (Kiklades, Greece)
    EDINBURGH JOURNAL OF BOTANY 72 ( 3 ): 391 – 412 (2015) 391 © Trustees of the Royal Botanic Garden Edinburgh (2015) doi:10.1017/S0960428615000128 CONTRIBUTION TO THE FLORA AND BIOGEOGRAPHY OF THE KIKLADES: FOLEGANDROS ISLAND (KIKLADES, GREECE) K . K OUGIOUMOUTZIS , A . T INIAKOU , O . G EORGIOU & T . G EORGIADIS The island of Folegandros, located between the Milos and Santorini archipelagos in the southern Kiklades (Greece), constitutes together with Ios and Sikinos the south-central part of the phytogeographical region of the Kiklades. Its flora consists of 474 taxa, 47 of which are under statutory protection, 40 are Greek endemics and 145 are reported here for the first time. We show that Folegandros has the highest percentage of Greek endemics in the phytogeographical area of the Kiklades. The known distribution of the endemic Muscari cycladicum subsp. cycladicum is expanded, being reported for the first time outside the South Aegean Volcanic Arc. The floristic cross-correlation between Folegandros and other parts of the phytogeographical region of the Kiklades by means of Sørensen’s index revealed that its phytogeographical affinities are stronger to Anafi Island than to any other part of the Kiklades. Keywords . Aegean flora , biodiversity , endemism , phytogeography . I NTRODUCTION The Aegean Sea has long attracted the attention of biogeographers (Turrill, 1929 ; Strid, 1996 ), since it is characterised by high environmental and topographical hetero- geneity (Blondel et al. , 2010 ), diversity and endemism (Strid, 1996 ). The Aegean archipelago consists of more than 7000 islands and islets (Triantis & Mylonas, 2009 ), most of which are located in the phytogeographical region of the Kiklades. Intensive field work has taken place in this region, which is characterised as one of the most floristically explored phytogeographical regions of Greece (Dimopoulos et al.

Based on natural selection, mutation and genetic drift, speciation occurs simultaneously in organisms linking them in complexes webs called ecosystems. Clarify what a species is, it is the first step to understand the biology of orchids and start protection actions especially in a fast changing world due to human impact such as habitats fragmentation and climate changes. I use the biological species concept (BSC) to investigate the presence and eventually the strength of mechanisms that limit the gene flow between close related taxa.
