CENTER FOR PLANT CONSERVATION ~ Missouri Botanical Garden St. Louis, Missouri July 15, l' 992 ACKNOWLEDGMENTS The Center for Plant Conservation would like to acknowledge the John D. and Catherine T. MacArthur Foundation and the W. Alton Jones Foundation for their generous support of the Center's work in the priority region of Puerto Rico. We would also like to thank all the participants in the task force meetings, without whose information this report would not be possible. Cover: Zanthoxy7um thomasianum is known from several sites in Puerto Rico and the U.S . Virgin Islands. It is a small shrub (2-3 meters) that grows on the banks of cliffs. Threats to this taxon include development, seed consumption by insects, and road erosion. The seeds are difficult to germinate, but Fairchild Tropical Garden in Miami has plants growing as part of the Center for Plant Conservation's .National Collection of Endangered Plants.

  • 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.

  • Diversidad De Plantas Y Vegetación Del Páramo Andino
    Plant diversity and vegetation of the Andean Páramo Diversidad de plantas y vegetación del Páramo Andino By Gwendolyn Peyre A thesis submitted for the degree of Doctor from the University of Barcelona and Aarhus University University of Barcelona, Faculty of Biology, PhD Program Biodiversity Aarhus University, Institute of Bioscience, PhD Program Bioscience Supervisors: Dr. Xavier Font, Dr. Henrik Balslev Tutor: Dr. Xavier Font March, 2015 Aux peuples andins Summary The páramo is a high mountain ecosystem that includes all natural habitats located between the montane treeline and the permanent snowline in the humid northern Andes. Given its recent origin and continental insularity among tropical lowlands, the páramo evolved as a biodiversity hotspot, with a vascular flora of more than 3400 species and high endemism. Moreover, the páramo provides many ecosystem services for human populations, essentially water supply and carbon storage. Anthropogenic activities, mostly agriculture and burning- grazing practices, as well as climate change are major threats for the páramo’s integrity. Consequently, further scientific research and conservation strategies must be oriented towards this unique region. Botanical and ecological knowledge on the páramo is extensive but geographically heterogeneous. Moreover, most research studies and management strategies are carried out at local to national scale and given the vast extension of the páramo, regional studies are also needed. The principal limitation for regional páramo studies is the lack of a substantial source of good quality botanical data covering the entire region and freely accessible. To meet the needs for a regional data source, we created VegPáramo, a floristic and vegetation database containing 3000 vegetation plots sampled with the phytosociological method throughout the páramo region and proceeding from the existing literature and our fieldwork (Chapter 1).

  • Explosive Local Radiation of the Genus Teagueia (Orchidaceae) in the Upper Pastaza Watershed of Ecuador
    Volume 7(1) Explosive Local Radiation of the Genus Teagueia (Orchidaceae) in the Upper Pastaza Watershed of Ecuador. Radiacion Explosivo del Genero Teagueia (Orchidaceae) en la Cuenca Alta del Rio Pastaza, Ecuador. Lou Jost Baños, Tungurahua, Ecuador, Email: [email protected] December 2004 Download at: http://www.lyonia.org/downloadPDF.php?pdfID=2.323.1 Lou Jost 42 Explosive Local Radiation of the Genus Teagueia (Orchidaceae) in the Upper Pastaza Watershed of Ecuador. Abstract In the year 2000 the genus Teagueia Luer (Orchidaceae, subtribe Pleurothallidinae) contained only six species, all epiphytic. Recently we have discovered 26 unusual new terrestrial species of Teagueia on four neighboring mountains in the Upper Pastaza Watershed. All 26 species share distinctive floral and vegetative characters not found in the six previously described members of Teagueia, suggesting that all 26 evolved locally from a recent common ancestor. Each of the Teagueia Mountains hosts 7-15 sympatric species of new Teagueia, suggesting that the speciation events, which produced this radiation, may have occurred in sympatric populations. There is little overlap in the Teagueia species hosted by the mountains, though they are separated by only 10-18 km. This is difficult to explain in light of the high dispersal ability of most orchids. Surprisingly, the species appear not to be habitat specialists. In forest above 3100 m, population densities of these new Teagueia are higher than those of any other genera of terrestrial flowering plants. In the paramos of these mountains they are the most common orchids; they reach higher elevations (3650m) than any other pleurothallid orchid except Draconanthes aberrans.

Historically, the isthmus of Costa Rica and Panama has been a source of fascination for its strategic position linking North America to South America. In terms of biodiversity, the isthmus is considered one of the richest regions in the world. Orchidaceae is the most diverse plant family in the area, and the number of species is triple that of other well-represented angiosperm families such as Rubiaceae, Fabaceae and Poaceae. Though we are still far from knowing the exact number of orchid species occurring extant in both countries nowadays, at present the orchid flora reported for Costa Rica (1574 spp.) and Panama (1372 spp.) summarise together about 2010 species; which represents 6.5-8.0% of all orchid species on just about 1% of the Earth’s land surface. Pleurothallidinae and Laeliinae are the most species rich groups and contain the largest genera: Lepanthes, Pleurothallis, Stelis and Epidendrum.

As recognized in this paper D. aberrans complex includes a total of 6 species, 3 of which are described here. New combinations are proposed for Lepanthes prionota and L. trachysepala. Two species, including D. aberrans, are lectotypified. The previous incorrect typifications are discussed. Each of 6 species is morphologically characterized. The perianth segments of all discussed taxa are illustrated. The key to identification of species belonging to theDraconanthes aberrans complex is presented together with the comparative morphology of studied taxa. Key words: Lepanthes, morphology, species complex, taxonomy 1. Introduction In 1996 Luer elevated subgenus Draconanthes to the Lepanthes Sw. subgenus Draconanthes Luer (Orchidaceae) rank of genus and modified species concept in it (Luer, was established in 1986 to accommodate 4 high-Andean 1996). He recognized only 2 species in the newly created species (Luer 1986).

Ackerman and collaborators published the last checklist of Cuban orchid species in the book, “Orchid Flora of the Greater Antilles”. The aim of our study was to determine the current number of orchid species in Cuba and adjacent islands culminating in an updated checklist.

We provide comments on taxonomic status on noteworthy species. KEY WORDS: taxonomy, checklist, orchids, Cuba Introduction.
