[email protected] Mauritia flexuosa has one of the widest distributions of all palms, covering millions of hectares across northern South America, where it forms extensive, high-density stands. How does a species reach this wide distribution and high abundance in the face of strong competition in hyperdiverse tropical forests as well as persist through extreme landscape and climate changes throughout the Cenozoic (last ca. 65 mya)? Evolutionary success is related to historical contingency, genetic variation, and demography. Here I present a robust approach to understanding diversification in the tribe Lepidocaryeeae, showing how clade competition contributed to persistence through geological time. Within the Mauritia lineage, I show extinction patterns using the pollen fossil record, leading to low species diversity in the genus. I also review how climatic change during the Quaternary influenced the extant demography and distribution of M. flexuosa. Mauritia flexuosa presents significant genetic differentiation among different river basins and between the Amazonian and Cerrado biomes. Touching on environmental correlations across the genome, I conclude by contrasting adaptive selection with genomic plasticity. Our work provides new insights into the historical factors that affected geographical distribution and structured genetic diversity, contributing to long-term evolutionary success. Key words: biome, demography, genetic diversity, outlier loci, phylogeny. Spikelet pairs in Andropogoneae Elizabeth A. Kellogg1 1Donald Danforth Plant Science Center. [email protected] Presence of paired spikelets is often used to help identify members of Andropogoneae. Developmentally, the paired spikelets originate from an enlarged branch meristem that converts rapidly to spikelet meristems, one sessile and one pedicellate, a pattern controlled by a uniquely derived genetic network. This pattern is shared even by species described as having triplets of spikelets (e.g. Sorghum, Chrysopogon), in which the triplet is actually a pair plus a terminal spikelet that is morphologically identical to the pedicellate one. The pair is also subtended by an abscission zone, the position of which is synapomorphic for Andropogoneae s.s. In other panicoid grasses, the abscission zone forms below the spikelet and the change in position occurred before diversification of the tribe. In Andropogoneae spikelets of the pair have partitioned the ancestral functions, with one being dedicated to seed bearing and largely encased in a hard covering (glume) and the other staminate, sterile or missing entirely. When present, the pedicellate spikelet serves as a nurse tissue providing photosynthate to the developing seed in the sessile spikelet. The diagnostic - and uniquely derived - character for Andropogoneae is thus not just the pair of spikelets, but also the position of the abscission zone, the underlying genetic network, and the functions in dispersal and photosynthesis. The morphology of a simple pair of spikelets thus offers additional layers of insight into evolutionary mechanisms and potential selective forces. Key words: dispersal, genetic network, pedicellate spikelet, photosynthesis, synapomorphy.

  • VESSELS in ERIOCAULACEAE By
    IAWA Journ al, Vol. 17 (2), 1996: 183-204 VESSELS IN ERIOCAULACEAE by Jennifer A. Thorsch & Vernon I. Cheadle I Department of Ecology, Evolution and Marine Biology, University of California, Santa Barbara, CA 93 106, U.S.A. SUMMARY The occ urrence and level of specialization of vesse ls in 70 species representing 12 genera of Eriocaulaceae are presented. In alI species of Eriocaulaceae and in alI parts of the plant examined, vessels with simple perforations have been identified . Correlations between level of specia­ lization of vessel members and ecological conditi ons are reported for species from diverse habitats and species with distinct differences in habit. The pattern of origin and specialization of tracheary celIs in Erio­ caulaceae was compared to tracheary data for Xyridaceae , Rapateaceae, Restionaceae and Centrolepidaceae. The evolutionary position of these families has been regarded as close to Eriocaulaceae. Key words: Eriocaulaceae, vessels, perforation plates, phylogenetic posi­ tion. INTRODUCTION This paper provides detailed information about perforation plates of vessels in Erio­ caulaceae, the 29th family we have similarly examined in monocotyledons. The near­ ly complete list of families analyzed in detail is given in the literature cited in the paper on Commelinales (Cheadle & Kosakai 1980). Our studies on the tracheary elements in monocotyledons have included families and species from a broad range of habits, habitats and geographical sites around the world. Families for study were selected based on three criteria: I) presence of alI plant parts, 2) variety of habits and habitats, and 3) broad representation of the species within the family. The data on tracheids and vessels from these broadly based studies led to the folIowing brief conclusions.

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.

  • Phylogeny of the American Amaryllidaceae Based on Nrdna ITS Sequences
    Systematic Botany (2000), 25(4): pp. 708±726 q Copyright 2000 by the American Society of Plant Taxonomists Phylogeny of the American Amaryllidaceae based on nrDNA ITS sequences ALAN W. M EEROW USDA-ARS-SHRS, 13601 Old Cutler Road, Miami, FL 33158 and Fairchild Tropical Garden, 10901 Old Cutler Road, Miami, Florida 33158 CHARLES L. GUY and QIN-BAO LI University of Florida, Department of Environmental Horticulture, 1545 Fi®eld Hall, Gainesville, Florida 32611 SI-LIN YANG University of Florida, Fort Lauderdale Research and Education Center, 3205 College Avenue, Fort Lauderdale, Florida 33314 Communicating Editor: Kathleen A. Kron ABSTRACT. Analysis of three plastid DNA sequences for a broad sampling of Amaryllidaceae resolve the American genera of the Amaryllidaceae as a clade that is sister to the Eurasian genera of the family, but base substitution rates for these genes are too low to resolve much of the intergeneric relationships within the American clade. We obtained ITS rDNA sequences for 76 species of American Amaryllidaceae and analyzed the aligned matrix cladistically, both with and without gaps included, using two species of Pancratium as outgroup taxa. ITS resolves two moderately to strongly supported groups, an Andean tetraploid clade, and a primarily extra-Andean ``hippeastroid'' clade. Within the hippeastroid clade, the tribe Grif®neae is resolved as sister to the rest of Hippeastreae. The genera Rhodophiala and Zephyranthes are resolved as polyphyletic, but the possibility of reticulation within this clade argues against any re-arrangement of these genera without further investigation. Within the Andean subclade, Eustephieae resolves as sister to all other tribes; a distinct petiolate-leafed group is resolved, combining the tribe Eucharideae and the petiolate Stenomesseae; and a distinct Hymenocallideae is supported.

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.

  • 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.

    Rodriguésia 63(1): 001-019. 2012 http://rodriguesia.jbrj.gov.br Molecular phylogeny, morphology and their implications for the taxonomy of Eriocaulaceae Filogenia molecular, morfologia e suas implicações para a taxonomia de Eriocaulaceae Ana M. Giulietti,1,7,8 Maria José G. Andrade,1,4 Vera L. Scatena,2 Marcelo Trovó,6 Alessandra I. Coan,2 Paulo T. Sano,3 Francisco A.R. Santos,1 Ricardo L.B. Borges,1,5 & Cássio van den Berg1 Abstract The pantropical family Eriocaulaceae includes ten genera and c. 1,400 species, with diversity concentrated in the New World. The last complete revision of the family was published more than 100 years ago, and until recently the generic and infrageneric relationships were poorly resolved. However, a multi-disciplinary approach over the last 30 years, using morphological and anatomical characters, has been supplemented with additional data from palynology, chemistry, embryology, population genetics, cytology and, more recently, molecular phylogenetic studies. This led to a reassessment of phylogenetic relationships within the family. In this paper we present new data for the ITS and trnL-F regions, analysed separately and in combination, using maximum parsimony and Bayesian inference. The data confirm previous results, and show that many characters traditionally used for differentiating and circumscribing the genera within the family are homoplasious. A new generic key with characters from various sources and reflecting the current taxonomic changes is presented. Key words: anatomy, ITS, phylogenetics, pollen, trnL-trnF. Resumo Eriocaulaceae é uma família pantropical com dez gêneros e cerca de 1.400 espécies, com centro de diversidade no Novo Mundo, especialmente no Brasil.

Freudenstein ABSTRACT. The chloroplast-encoded gene rbcL was sequenced in 30 genera of Commelinaceae to evaluate intergeneric relationships within the family. The Australian Cartonema was consistently placed as sister to the rest of the family. The Commelineae is monophyletic, while the monophyly of Tradescantieae is in question, due to the position of Palisota as sister to all other Tradescantieae plus Commelineae. The phylogeny supports the most recent classi®cation of the family with monophyletic tribes Tradescantieae (minus Palisota) and Commelineae, but is highly incongruent with a morphology-based phylogeny. This incongruence is attributed to convergent evolution of morphological characters associated with pollination strategies, especially those of the androecium and in¯orescence. Analysis of the combined data sets produced a phylogeny similar to the rbcL phylogeny. The combined analysis differed from the molecular one, however, in supporting the monophyly of Dichorisandrinae. The family appears to have arisen in the Old World, with one or possibly two movements to the New World in the Tradescantieae, and two (or possibly one) subsequent movements back to the Old World; the latter are required to account for the Old World distribution of Coleotrypinae and Cyanotinae, which are nested within a New World clade.
