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.

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 Melisa Alegría-Valencia Copyright (c) 2024 Lankesteriana: International Journal on Orchidology 2024-02-23 2024-02-23 49–60 49–60 10.15517/lank.v24i1.57040 <i>Malaxis engelsii</i> (Malaxidinae), a new species from the upper montane forest of the Atlantic Rainforest in southern Brazil <div class="page" title="Page 1"> <div class="layoutArea"> <div class="column"> <p><em>Malaxis engelsii</em> is a newly discovered orchid found in the upper montane forests of the Atlantic Rainforest in Paraná, Brazil.

In Costa Rica, this genus includes 55 species, with 16 classified as small-flowered species. While the large-flowered species of <em>Telipogon</em> (in the strict sense) have been taxonomically revised, the small-flowered species have yet to be the subject of a thorough taxonomic revision. Our research aims to partially fill this gap by focusing on a comparative morphological analysis of two novel small-flowered <em>Telipogon</em> species. We describe and illustrate <em>Telipogon lateritius</em> and <em>T. muntzii</em>, both discovered in the humid mid-elevation forest of the Caribbean watershed in Cordillera de Talamanca, Costa Rica. <em>Telipogon lateritius</em> is notable for its distinctive brick-colored flowers, featuring sepals, petals, and lips striped in chestnut brown; the lateral sepals connate into a triangular-ovate synsepal, complemented by sparse, stiff pubescence at the base of the lip. <em>Telipogon muntzii</em>, although closely resembling <em>T. anacristinae</em>, differs in its unique olive-green flowers, sparse trichomes on the lip, narrowly oblong lateral lobes of the column, and a helmet-shaped median lobe of the column exclusively covered by simple trichomes. This study provides new additions for a future taxonomic revision of <em>Telipogon</em> in Costa Rica.</p> Diego Bogarín Franco Pupulin Oscar A.

We found that the orchid grows on a subset of the available tree species and shows preference for the endemic <em>Machaonia portoricensis </em>(Rubiaceae). The orchid preferred trees with smoother bark with high water holding capacity and low water retention capacity. Microclimatic conditions under which embryos began pre-germination stages mirrored that of the adult orchid, but germination did not, suggesting that suitable germination sites are not necessarily the best sites for later stages of development.<span class="Apple-converted-space">&nbsp;</span></p> Normandie González-Orellana Aragne Salazar Mendoza Raymond L.
