Generic and Subtribal Relationships in Neotropical Cymbidieae (Orchidaceae) Based on Matk/Ycf1 Plastid Data
LANKESTERIANA 13(3): 375—392. 2014. I N V I T E D P A P E R* GENERIC AND SUBTRIBAL RELATIONSHIPS IN NEOTROPICAL CYMBIDIEAE (ORCHIDACEAE) BASED ON MATK/YCF1 PLASTID DATA W. 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.

Aerangis Articulata by Brenda Oviatt and Bill Nerison an Exquisite Star from Madagascar
COLLECTor’s item by Brenda Oviatt and Bill Nerison Aerangis articulata An Exquisite Star from Madagascar IN ALL HONESTY, WHEN WE FOUND out that our photo of Aerangis articulata was chosen for the cover of Isobyl la Croix’s (2014) new book Aerangis, we were more than just a little excited! We decided that this is a perfect opportunity to tell people more about Aergs. articulata and give an introduction to her new book. We will try and help clarify the confusion surrounding the identification of this species, describe what to look for if you intend to buy one and discuss culture to help you grow and bloom it well. We love angraecoids, and the feature that most share and what sets them apart is their spurs or nectaries. In some orchid species, attracting the pollinator is all about fooling someone (quite often an insect). Some will mimic a female insect while others will mimic another type of flower to attract that flower’s pollinator. Oftentimes the u n s u s p e c t i n g insect gets nothing in return; not the promised mate or the nectar of the Brenda Oviatt and mimicked flower. Bill Nerison With angraecoids, the pollinator is often rewarded with a sweet treat: nectar that sits in the bottom of the spur. The pollinator of Aergs. articulata is a hawk moth (DuPuy, et al 1999) whose proboscis can reach that nectar. These moths are attracted by the sweet nighttime fragrance TT (scented much like a gardenia) and by the A VI O white flower (more visible than a colored A D flower in the dark). -

Ackerman Tag der mündlichen Prüfung: 06.02.2004 Pleurothallis obliquipetala Acuña & Schweinf. Für Jakob und Julius, die nichts unversucht ließen, um das Zustandekommen dieser Arbeit zu verhindern. Zusammenfassung Die antillanische Flora ist eine der artenreichsten der Erde. Trotz jahrhundertelanger floristischer Forschung zeigen jüngere Studien, daß der Archipel noch immer weiße Flecken beherbergt. Das trifft besonders auf die Familie der Orchideen zu, deren letzte Bearbeitung für Cuba z.B. mehr als ein halbes Jahrhundert zurückliegt. Die vorliegende Arbeit basiert auf der lang ausstehenden Revision der Orchideengattung Pleurothallis R. Br. für die Flora de Cuba. Mittels weiterer morphologischer, palynologischer, molekulargenetischer, phytogeographischer und ökologischer Untersuchungen auch eines Florenteils der anderen Großen Antillen wird die Genese der antillanischen Pleurothallis-Flora rekonstruiert. Der Archipel umfaßt mehr als 70 Arten dieser Gattung, wobei die Zahlen auf den einzelnen Inseln sehr verschieden sind: Cuba besitzt 39, Jamaica 23, Hispaniola 40 und Puerto Rico 11 Spezies. Das Zentrum der Diversität liegt im montanen Dreieck Ost-Cuba – Jamaica – Hispaniola, einer Region, die 95 % der antillanischen Arten beherbergt, wovon 75% endemisch auf einer der Inseln sind. -

Box 302-7050 Cartago, Costa Rica. 7Naturalis Biodiversity Center, Leiden, The Netherlands. Abstract Most of the species studied in this paper have previously been placed in either Pleurothallis or Lepanthes. However, at one time or another, members of the group have also been placed in the genera Andinia, Brachycladium, Lueranthos, Masdeval- liantha, Neooreophilus, Oreophilus, Penducella, Salpistele and Xenosia. Phylogenetic analyses of nuclear ITS and plastid matK sequences indicate that these species form a strongly supported clade that is only distantly related to Lepanthes and is distinct from Pleurothallis and Salpistele. Since this clade includes the type species of Andinia, A. dielsii, and it has taxo- nomic precedence over all other generic names belonging to this group, Andinia is re-circumscribed and expanded to include 72 species segregated into five subgenera: Aenigma, Andinia, Brachycladium, Masdevalliantha and Minuscula. -

The entire chloroplast (cp) genome of asparagus was sequenced with Hiseq4000 platform. The complete cp genome maps a circular molecule of 156,699bp built with a quadripartite organization: two inverted repeats (IRs) of 26,531bp, separated by a large single copy (LSC) sequence of 84,999bp and a small single copy (SSC) sequence of 18,638bp. A total of 112 genes comprising of 78 protein-coding genes, 30 tRNAs and 4 rRNAs were successfully annotated, 17 of which included introns. The identity, number and GC content of asparagus cp genes were similar to those of other asparagus species genomes. Analysis revealed 81 simple sequence repeat (SSR) loci, most composed of A or T, contributing to a bias in base composition. A maximum likelihood phylogenomic evolution analysis showed that asparagus was closely related to Polygonatum cyrtonema that belonged to the genus Asparagales. -
A New Species of Pterichis (Orchidaceae) from Ecuador Marta Kolanowska & Dariusz L
© Landesmuseum für Kärnten; download www.landesmuseum.ktn.gv.at/wulfenia; www.zobodat.at Wulfenia 22 (2015): 221–224 Mitteilungen des Kärntner Botanikzentrums Klagenfurt A new species of Pterichis (Orchidaceae) from Ecuador Marta Kolanowska & Dariusz L. Szlachetko Summary: A new species of Pterichis, P. elliptica, is described based on Ecuadorian material. It resembles P. pauciflora, but can be easily distinguished from this species based on the lip form. Morphological characteristics of the novelty are complemented with illustrations and taxonomic notes. The updated key to Ecuadorian species of Pterichis is provided. Keywords: biodiversity, Cranichidinae, Neotropics, orchids, taxonomy, new species The Andean orchid flora remains poorly recognized and numerous new species from this region are described every year (e.g. Noguera-Savelli et al. 2008; Carnevali & Cetzal-Ix 2012). Unfortunately, transformations of the mountain vegetation in South America caused by human activities and global climate warming severely disturb the environmental sustainability of high- Andean forest, subparamo and paramo (Buytaert et al. 2006). This habitat loss is by far the main threat to most orchids (Hágsater & Dumont 1996), especially to those strictly related to specific bioclimatic conditions of high mountains. The diversity of such plants deserves particular attention of taxonomists. Our recent studies were focused on the genus Pterichis which was described in 1840 by John Lindley based on a Peruvian plant. The majority of species is distributed along the Andes from Colombia and Venezuela in the north to Bolivia in the south, and only a few occur in Costa Rica and Jamaica. Plants grow usually in subparamo or paramo, but some population were also found in the high-montane forest. -
