Lankesteriana: International Journal on Orchidology <p><a href="">LANKESTERIANA</a>, the Scientific Journal of <a href="">Jardín Botánico Lankester</a> - Universidad de Costa Rica, is devoted to the publication of original contributions on orchidology, including orchid systematics, ecology, evolution, anatomy, physiology, history, etc., as well as reviews of books and conferences on these topics. Short communications and commentaries are also accepted and should be titled as such. The official language of the journal is English (papers are published with a Spanish summary), and manuscripts submitted in Spanish will be considered case by case. Manuscripts are evaluated critically by two or more external referees, in double-blind mode. </p> <p>Through <a href=""><strong>Early View</strong></a>, Lankesteriana is committed to considering shortening the times requested for effective publication of scientific, peer-reviewed papers, for the benefit of both the authors and the readers of the journal. The papers in this section of Lankesteriana receive an individual DOI and are published online as soon as the editorial process is concluded positively. They represent early views of the final papers exactly as they will be included in the hard-printed, complete issue of the journal. The effective date of publication of each paper is established by the date of its first publication online, which is recorded on the front page of the paper both in its online and hard-printed versions. The printed version of LANKESTERIANA is published periodically in volumes by the Lankester Botanical Garden, University of Costa Rica. Each volume is made up of three issues published in April (covers the period from January to April), August (covers from May to August), and December (covers from September to December).</p> <p>LANKESTERIANA is indexed by Clarivate Biosis, <a href=";pid=1409-3871&amp;lng=en&amp;nrm=iso">SciELO</a>, <a href="">Scopus</a>, <a href=";context=L&amp;vid=01USC_INST:01USC&amp;lang=en&amp;search_scope=MyInstitution&amp;adaptor=Local%20Search%20Engine&amp;tab=LibraryCatalog&amp;query=any,contains,lankesteriana&amp;sortby=rank&amp;offset=0">Scirus</a>, <a href=";colors=3&amp;lang=en&amp;jour_id=125187">WZB</a>, <a href="">Redalyc</a>, <a href="">DOAJ</a>, <a href=";acc_sequence=000666735">PERIODICA</a>, <a href="">BIBLAT</a>, <a href="">The Latindex Directory</a>, and it is included in databases such as <a href="">E-journals</a>, Ebookbrowse, FAO Online Catalogues, CiteBank, Mendeley, WorldCat, <a href="">Core Electronic Journals Library</a>, and Biodiversity Heritage Library, and in the electronic resources of the <a href="">Columbia University</a>, the <a href="">University of Florida</a>, the University of Hamburg, and the <a href="">Smithsonian Institution</a>, among others. </p> <p class="p1">The Lankester Botanical Garden is a research center of the University of Costa Rica, LANKESTERIANA´ s publishing institution, which holds the copyright and publishing rights of every contribution, under a Creative Commons Attribution-Non-Commercial-No Derivatives 3.0 Costa Rica license (<a href="">CC BY-NC-ND 3.0 CR</a>).</p> <p>Postmaster: Lankester Botanical Garden, University of Costa Rica, P.O.

Information is provided to separate between the species belonging to the Arbuscula and Incomptum groups. Moreover, the new taxon described here, <em>Epidendrum pembertonii</em>, is thoroughly compared with the four most morphologically similar species (<em>E. brenesii</em>, <em>E. bisulcatum</em>, <em>E. foldatsii</em>, <em>E. sotoanum</em>), showing notable differences in the number and shape of leaves, inflorescence length, color of flowers, sepals venation, shape and ornamentation of the lip and column.</p> Milton Rincón-González, Elizabeth Santiago Ayala, Eric Hágsater, Sebastián Vieira-Uribe Copyright (c) 2024 Lankesteriana: International Journal on Orchidology Tue, 13 Feb 2024 00:00:00 -0600 Notes on australasian orchids 8: Eight new species of <i>Hymenochilus</i> (Cranichideae: Pterostylidinae) and clarification of two previously described species <p>Eight new species of<em> Hymenochilus </em>from Australia are described and illustrated. Six of the new species have affinities to (and are here compared with) <em>H</em>. <em>cycnocephalus</em>: <em>H. anemophilus, H. calcicola, H. cymbellus</em>, <em>H. longipes, H. nemoralis </em>and<em> H. pachylus</em>. <em>Hymenochilus anemophilus</em> is shorter (2–8 cm)<em>, </em>with dark green strongly veined rosette leaves, crowded dark green flowers, oblong to obovate labellum lamina and, a broader blunter beak on the labellum appendage; <em>H. calcicola</em> is shorter (3–12 cm), crowded green flowers with prominent dark green stripes, ovate petals with a strongly developed basal flange on the anterior side and narrow elliptic labellum lamina with a broad pointed beak on the labellum appendage; <em>H. cymbellus</em> differs by its sparser basal rosette with narrower rosette leaves, thinner scapes, flowers with distinct darker green stripes and shallowly saccate lateral sepals that narrow inwards to a distinctly pointed apex; <em>H. longipes</em> differs by its thin-textured rosette leaves, widely spaced darker green flowers with darker green veins, elliptic-obovate labellum lamina and a longer labellum basal appendage which protrudes prominently from the flower in side view; <em>H. nemoralis</em> has longer rosette leaves, thicker scape &nbsp;and darker green flowers with prominent narrow dark green stripes; <em>H. pachylus</em> has thicker rosette leaves, taller, thicker scape, flowers prominently striped, elliptic-obovate labellum lamina and labellum appendage with a short thick beak. Two of the new species have affinities (and are here compared) with <em>H. muticus</em>: <em>H. pagophilus </em>and<em> H. pisinnus</em>. <em>Hymenochilus pagophilus</em> differs by its moderately crowded to crowded flowers, broader, shinier flowers and rectangular-obovate labellum and <em>H. pisinnus</em> differs by its smaller rosette with smaller, narrower leaves, thinner scape, smaller flowers, that are often on long pedicels, shorter, shallowly saccate lateral sepals, smaller rhomboid petals and, smaller obovate labellum. In addition, <em>Hymenochilus cycnocephalus </em>and <em>H. muticus, </em>are characterised in the strict sense with full descriptions, distribution, and habitat.&nbsp;</p> David L. Jones, Heidi C.

We also provide comparisons with similar species and offer comments on their ecology. Furthermore, we discuss the significance of this highly anthropized region and its richness in orchid species.</p> Nicolás Gutiérrez Morales, Juan Sebastian Moreno, Karen Gil Amaya, Melissa Alegría Valencia Copyright (c) 2024 Lankesteriana: International Journal on Orchidology Fri, 23 Feb 2024 00:00:00 -0600
