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. -
Generic and Subtribal Relationships in Neotropical Cymbidieae (Orchidaceae) Based on Matk/Ycf1 Plastid Data
LANKESTERIANA 13(3): 375—392. 2014. I N V I T E D P A P E R* GENERIC AND SUBTRIBAL RELATIONSHIPS IN NEOTROPICAL CYMBIDIEAE (ORCHIDACEAE) BASED ON MATK/YCF1 PLASTID DATA W. MARK WHITTEN1,2, KURT M. NEUBIG1 & N. H. WILLIAMS1 1Florida Museum of Natural History, University of Florida Gainesville, FL 32611-7800 USA 2Corresponding author: [email protected] ABSTRACT. Relationships among all subtribes of Neotropical Cymbidieae (Orchidaceae) were estimated using combined matK/ycf1 plastid sequence data for 289 taxa. The matrix was analyzed using RAxML. Bootstrap (BS) analyses yield 100% BS support for all subtribes except Stanhopeinae (87%). Generic relationships within subtribes are highly resolved and are generally congruent with those presented in previous studies and as summarized in Genera Orchidacearum. Relationships among subtribes are largely unresolved. The Szlachetko generic classification of Maxillariinae is not supported. A new combination is made for Maxillaria cacaoensis J.T.Atwood in Camaridium. KEY WORDS: Orchidaceae, Cymbidieae, Maxillariinae, matK, ycf1, phylogenetics, Camaridium, Maxillaria cacaoensis, Vargasiella Cymbidieae include many of the showiest align nrITS sequences across the entire tribe was Neotropical epiphytic orchids and an unparalleled unrealistic due to high levels of sequence divergence, diversity in floral rewards and pollination systems. and instead to concentrate our efforts on assembling Many researchers have posed questions such as a larger plastid data set based on two regions (matK “How many times and when has male euglossine and ycf1) that are among the most variable plastid bee pollination evolved?”(Ramírez et al. 2011), or exon regions and can be aligned with minimal “How many times have oil-reward flowers evolved?” ambiguity across broad taxonomic spans. -

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. -

Wita Stwosza 59, 80-308 Gdańsk, Poland. [email protected] Abstract. The floristic, geographical and ecological analysis of the orchid flora of the department of Valle del Cauca are presented. The study area is located in the southwestern Colombia and it covers about 22 140 km2 of land across 4 physiographic units. All analysis are based on the fieldwork and on the revision of the herbarium material. A list of 572 orchid species occurring in the department of Valle del Cauca is presented. Two species, Arundina graminifolia and Vanilla planifolia, are non-native elements of the studied orchid flora. The greatest species diversity is observed in the montane regions of the study area, especially in wet montane forest. -
Epilist 1.0: a Global Checklist of Vascular Epiphytes
Zurich Open Repository and Archive University of Zurich Main Library Strickhofstrasse 39 CH-8057 Zurich www.zora.uzh.ch Year: 2021 EpiList 1.0: a global checklist of vascular epiphytes Zotz, Gerhard ; Weigelt, Patrick ; Kessler, Michael ; Kreft, Holger ; Taylor, Amanda Abstract: Epiphytes make up roughly 10% of all vascular plant species globally and play important functional roles, especially in tropical forests. However, to date, there is no comprehensive list of vas- cular epiphyte species. Here, we present EpiList 1.0, the first global list of vascular epiphytes based on standardized definitions and taxonomy. We include obligate epiphytes, facultative epiphytes, and hemiepiphytes, as the latter share the vulnerable epiphytic stage as juveniles. Based on 978 references, the checklist includes >31,000 species of 79 plant families. Species names were standardized against World Flora Online for seed plants and against the World Ferns database for lycophytes and ferns. In cases of species missing from these databases, we used other databases (mostly World Checklist of Selected Plant Families). For all species, author names and IDs for World Flora Online entries are provided to facilitate the alignment with other plant databases, and to avoid ambiguities. EpiList 1.0 will be a rich source for synthetic studies in ecology, biogeography, and evolutionary biology as it offers, for the first time, a species‐level overview over all currently known vascular epiphytes. At the same time, the list represents work in progress: species descriptions of epiphytic taxa are ongoing and published life form information in floristic inventories and trait and distribution databases is often incomplete and sometimes evenwrong. -

The user has requested enhancement of the downloaded file. The Genus Systeloglossum ROBERT L. DRESSLER AND NORRIS H. WILLIAMS HE COMPLEX OF GENERA which make up the subtribe Oncidiinae are notable for their great diversity of flower structure. It is not surprising T that Schlechter grouped these genera into as many as ten different btribes. How can one imagine close relationships between Notylia and ~richoPilia, or Quekettia and Odontoglossum? In spite of their striking differences, we now group them all into the subtribe Oncidiinae, for two 'mportant reasons. First, crossing experiments, especially those of Mr. Moir, ~ave shown that the whole group is closely tied together by interfertility. We may not be able to cross Comparettia with Brassia, but we can cross both with Oncidium. The second reason for grouping them together is that even the morphological differences do not hold up very well on close inspection. Notylia may seem very different from Trichopilia, but Notylia and Macradenia are surely closely related, and Macradenia and Trichopilia subulata are perhaps more similar to each other than T . -

Comparative vegetative anatomy and systematics of the Oncidiinae (Maxillarieae, Orchidaceae) WILLIAM LOUIS STERN and BARBARA S. CARLSWARD Abstract Subtribe Oncidiinae comprises a vegetatively heterogeneous assemblage of species that has persistently been incapable of organization. Anatomy was considered to be a possible means to resolve the perplexity of relationships amongst the constituent taxa. The consistent occurrence of a foliar hypodermis, homogeneous mesophyll, conical silica bodies in stegmata, and ubiquitous fibre bundles in leaves provides a matrix for linKing the taxa, as do the parenchymatous pith and O-thickened endodermal cell walls in roots. However, the strict consensus of the 40 genera studied was completely unresolved, suggesting that vegetative characters alone are insufficient to assess the relationships amongst these taxa, a conclusion also reached for the remainder of Maxillarieae.
