Greengrowers: 10 AM, Saturday, June 26 @ Ben Lyda’s greenhouses Come, see, ask questions. Visiting another grower’s greenhouses and growing areas is always a great way to learn more about the art of growing orchids. If you’re not broke and out of space after the auction, Ben can help you out with some fine selections from his collection. See page 15 for directions.

This epiphyte, characterized by flattened 770-270-5758 pseudobulbs with two apical leaves, produces pendent inflorescences from the base of the developing new growth. These are often quite Secretary apparent before the new growth is more than an inch or two in length. Teresa Fuller They emerge from within the lower-most sheathing bract, just barely 2090 Rockdale Circle clearing the bract before turning sharply downward. Once fully Snellville GA 30078 770-972-2634 developed, the inflorescences can be more than 18 inches long and carry 10 or more 5 cm light pink or white flowers on the distal 6-12 Treasurer inches of the inflorescence. Scott Smith Mature pseudobulbs are laterally compressed, dull gray green to 481 W. Ontario Ave. Atlanta, GA 30310 glossy apple green, about 3 inches tall; and, some wrinkling with age 404-752-6432 is normal. The two apical leaves, up to 12 inches long, are ligulate, leathery and have no obvious petiole. Immediate Past President The plants occur at moderate elevations making them amenable to Linda Miller intermediate growing conditions with moderate shade although they 135 Pheasant Drive Marietta, GA 30067 do benefit from cooler nights. A slightly drier rest period after the 770-953-2853 growth has matured is also beneficial.

David Tomassini Collier/Reinke Red Lc. Ann Akagi 'H & R', HCC/AOS Coombs White Broughtonia (Laeliopsis) domingensis Collier/Reinke White Slc. Fire Lighter Collier/Reinke Potinara David Tomassini : This grex is a cross of Lc. Brilliant Orange and Pot. Free Spirit. The latter parent is 50% Sc. Beaufort and its hard to overcome the dominance of Pot. Free Spirit for the production of small to mid-sized yellows that look almost identical to the parent. In this Pot. David Tomassini case, Lc. Brilliant Orange is a complex hybrid involving predominantly all unifoliate Cattleya species with Laelia harpophylla and Laelia cinnabarina in the fourth generation back as the source of orange color. These species are dominant for flower count and color except when paired against Sophronitis coccinea. On the one side a fairly large plant, moderate flower size and numerous flowers per inflorescence and on the other side a small plant with one or two flowers. The result…..a slightly larger plant with one or two flowers slightly larger than Pot. Free Spirit with almost exactly the same color pattern. Broughtonia domingensis : This is one of those plants that seems to change name with regular frequency. The problem here is what to do with the genus Laeliopsis. Current thinking, apparently based on molecular phylogeny, has dissolved the genus and returned this species to Broughtonia. In any case, this pretty species is endemic to the Hispaniola and Mona Island, a small island off the eastern coast of Puerto Rico. As with other closely related Caribbean species very warm temperatures and typically very bright light are requisites to good culture. CLASS 2: CYMBIDIUM : No entries CLASS 3: DENDROBIUM Blue Den.

  • 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.

    A MONOGRAPH OF THE GENUS LOCKHARTIA (ORCHIDACEAE: ONCIDIINAE) By MARIO ALBERTO BLANCO-COTO A DISSERTATION PRESENTED TO THE GRADUATE SCHOOL OF THE UNIVERSITY OF FLORIDA IN PARTIAL FULFILLMENT OF THE REQUIREMENTS FOR THE DEGREE OF DOCTOR OF PHILOSOPHY UNIVERSITY OF FLORIDA 2011 1 © 2011 Mario Alberto Blanco-Coto 2 To my parents, who have always supported and encouraged me in every way. 3 ACKNOWLEDGMENTS Many individuals and institutions made the completion of this dissertation possible. 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.
