Corresponding author: Carlos Martel, [email protected] Abstract Telipogon jucusbambae, a Peruvian endemic species, is rediscovered and its distributional range greatly extended. The species was known from a single collection made more than 50 years ago. A description, images of living specimens, a distribution map, and taxonomic comments on related species are provided. Furthermore, we propose the T. falcatus species complex for a group of species closely related to T. jucusbambae.

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.

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.

  • 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.

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.

First, I thank my committee chair, Norris H. Williams, for his continuing support, encouragement and guidance during all stages of this project, and for providing me with the opportunity to visit and do research in Ecuador. W. Mark Whitten, one of my committee members, also provided much advice and support, both in the lab and in the field. Both of them are wonderful sources of wisdom on all matters of orchid research. I also want to thank the other members of my committee, Walter S. Judd, Douglas E. Soltis, and Thomas J. Sheehan for their many comments, suggestions, and discussions provided. Drs. Judd and Soltis also provided many ideas and training through courses I took with them. I am deeply thankful to my fellow lab members Kurt Neubig, Lorena Endara, and Iwan Molgo, for the many fascinating discussions, helpful suggestions, logistical support, and for providing a wonderful office environment. Kurt was of tremendous help in the lab and with Latin translations; he even let me appropriate and abuse his scanner. Robert L. Dressler encouraged me to attend the University of Florida, provided interesting discussions and insight throughout the project, and was key in suggesting the genus Lockhartia as a dissertation subject.

LegionÛw 9, 80-441 GdaÒsk, Poland, *e-mail: [email protected] Abstract: A new species of the genus Telipogon from Southern Ecuador is formally described and illustrated. This species is related to T. fritillum and T. dalstroemii but is clearly distinguished from both of them by its different petals and lip structure. Key words: Orchidaceae, Telipogon, new species, Ecuador 1. Introduction often transverse, prominently veined and usually reticulated. The lip is very similar to the petals but is Telipogon Kunth (Orchidaceae, Vandoideae) occurs often broader or rarely smaller, commonly simple and in Central and South America, from Costa Rica to sessile. The column is usually abbreviated, footless and Venezuela, and throughout the Andes from Colombia wingless, long-setose or hispid; the anther is erect, to Bolivia. The genus consists of approximately 135 distinctly 2-celled, and the pollinia are 4 in number species, of which 50 are known from Ecuador (Dodson (Schweinfurth 1961; Szlachetko 2003). 2003). The species of Telipogon grow as terrestrials or The species of Telipogon are probably pollinated by epiphytes in montane rainforests. Some of them are flies of the Tachinidae family. The flies are common in endemic to small areas and sometimes may be restricted habitats where the plants occur. Most of the insects have to a single valley (Nauray Huari & Gal·n de Mera 2008).

Phylogenetic relationships of Telipogon Kunth, Ornithocephalus Hook. and related genera (Orchidaceae: Oncidiinae) were evaluated using parsimony analyses of data from the internal transcribed spacers of nuclear ribosomal (nrITS DNA) and three plastid regions (matK, trnL-F, and the atpB-rbcL intergenic spacer region). In addition to an analysis of 81 OTU’s for ITS only, we used a matrix of 30 taxa for combined nuclear and plastid analyses. Stellilabium is embedded within Telipogon and should be merged with the latter genus.
