Phylogeny and Classification of the Melastomataceae and Memecylaceae
Nord. J. Bot. - Section of tropical taxonomy Phylogeny and classification of the Melastomataceae and Memecy laceae Susanne S. Renner Renner, S. S. 1993. Phylogeny and classification of the Melastomataceae and Memecy- laceae. - Nord. J. Bot. 13: 519-540. Copenhagen. ISSN 0107-055X. A systematic analysis of the Melastomataceae, a pantropical family of about 4200- 4500 species in c. 166 genera, and their traditional allies, the Memecylaceae, with c. 430 species in six genera, suggests a phylogeny in which there are two major lineages in the Melastomataceae and a clearly distinct Memecylaceae. Melastomataceae have close affinities with Crypteroniaceae and Lythraceae, while Memecylaceae seem closer to Myrtaceae, all of which were considered as possible outgroups, but sister group relationships in this plexus could not be resolved. Based on an analysis of all morph- ological and anatomical characters useful for higher level grouping in the Melastoma- taceae and Memecylaceae a cladistic analysis of the evolutionary relationships of the tribes of the Melastomataceae was performed, employing part of the ingroup as outgroup. Using 7 of the 21 characters scored for all genera, the maximum parsimony program PAUP in an exhaustive search found four 8-step trees with a consistency index of 0.86. Because of the limited number of characters used and the uncertain monophyly of some of the tribes, however, all presented phylogenetic hypotheses are weak. A synapomorphy of the Memecylaceae is the presence of a dorsal terpenoid-producing connective gland, a synapomorphy of the Melastomataceae is the perfectly acrodro- mous leaf venation. Within the Melastomataceae, a basal monophyletic group consists of the Kibessioideae (Prernandra) characterized by fiber tracheids, radially and axially included phloem, and median-parietal placentation (placentas along the mid-veins of the locule walls). -

PhytoKeys 136: 1–21. https://doi.org/10.3897/ phytokeys.136.38558 Abstract The systematics of Tryssophyton, herbs endemic to the Pakaraima Mountains of western Guyana, is re- viewed and Tryssophyton quadrifolius K.Wurdack & Michelang., sp. nov. from the summit of Kamakusa Mountain is described as the second species in the genus. The new species is distinguished from its closest relative, Tryssophyton merumense, by striking vegetative differences, including number of leaves per stem and leaf architecture. A phylogenetic analysis of sequence data from three plastid loci and Melastomata- ceae-wide taxon sampling is presented. The two species of Tryssophyton are recovered as monophyletic and associated with mostly Old World tribe Sonerileae. Fruit, seed and leaf morphology are described for the first time, biogeography is discussed and both species are illustrated. -

Plant Structure in the Brazilian Neotropical Savannah Species
Chapter 16 Plant Structure in the Brazilian Neotropical Savannah Species Suzane Margaret Fank-de-Carvalho, Nádia Sílvia Somavilla, Maria Salete Marchioretto and Sônia Nair Báo Additional information is available at the end of the chapter http://dx.doi.org/10.5772/59066 1. Introduction This chapter presents a review of some important literature linking plant structure with function and/or as response to the environment in Brazilian neotropical savannah species, exemplifying mostly with Amaranthaceae and Melastomataceae and emphasizing the environment potential role in the development of such a structure. Brazil is recognized as the 17th country in megadiversity of plants, with 17,630 endemic species among a total of 31,162 Angiosperms [1]. The focus in the Brazilian Cerrado Biome (Brazilian Neotropical Savannah) species is justified because this Biome is recognized as a World Priority Hotspot for Conservation, with more than 7,000 plant species and around 4,400 endemic plants [2-3]. The Brazilian Cerrado Biome is a tropical savannah-like ecosystem that occupies about 2 millions of km² (from 3-24° Latitude S and from 41-43° Longitude W), with a hot, semi-humid seasonal climate formed by a dry winter (from May to September) and a rainy summer (from October to April) [4-8]. Cerrado has a large variety of landscapes, from tall savannah woodland to low open grassland with no woody plants and wetlands, as palm swamps, supporting the richest flora among the world’s savannahs-more than 7,000 native species of vascular plants- with high degree of endemism [3, 6]. The “cerrado” word is used to the typical vegetation, with grasses, herbs and 30-40% of woody plants [9-10] where trees and bushes display contorted trunk and branches with thick and fire-resistant bark, shiny coriaceous leaves and are usually recovered with dense indumentum [10]. -

How Many Vascular Plant Species Are There in a Local Hotspot of Biodiversity in Southeastern Brazil?
Neotropical Biology and Conservation 8(3):132-142, september-december 2013 © 2013 by Unisinos - doi: 10.4013/nbc.2013.83.03 How many vascular plant species are there in a local hotspot of biodiversity in Southeastern Brazil?

Markus Gastauer1 [email protected] Abstract Scientific information about the distribution of species richness and diversity is neces- João Augusto Alves Meira Neto2* sary for full comprehension of our evolutionary heritage forming a powerful tool for the [email protected] development of nature conservation strategies. The aim of this article was to estimate the vascular plant species richness of the campos rupestres from the Itacolomi State Park (ISP) in order to verify the park´s classification as a local hotspot of biodiversity and to outline the status quo of knowledge about biodiversity in the region. For that, the species richness of two phytosociological surveys of 0.15 ha each were extrapolated using (a) the species-area relationship fitted by the power and the logarithmic model as well as (b) the taxon ratio model. The taxon ratio model estimates total vascular plant species rich- ness to 1109 species using seven different taxa. Extrapolations of different fittings of the species-area relationships calculate the complete park’s richness to values between 241 and 386 (logarithmic model), and 3346 to 10421 (power model). These extrapolations are far beyond realistic: the logarithmic model underestimates the park´s species richness, because more than 520 vascular plant species have already been registered in the park. -

Molecular Phylogenetics of Melastomataceae and Memecylaceae: Implications for Character Evolution1

RENNER3,4 2Institut fuÈr Spezielle Botanik, UniversitaÈt Mainz, D-55099 Mainz, Germany; 3Department of Biology, University of Missouri-St. Louis, 8001 Natural Bridge Rd., St. Louis, Missouri 63121 USA; and The Missouri Botanical Garden, St. Louis, Missouri 63166 USA Melastomataceae are among the most abundant and diversi®ed groups of plants throughout the tropics, but their intrafamily rela- tionships and morphological evolution are poorly understood. Here we report the results of parsimony and maximum likelihood (ML) analyses of cpDNA sequences from the rbcL and ndhF genes and the rpl16 intron, generated for eight outgroups (Crypteroniaceae, Alzateaceae, Rhynchocalycaceae, Oliniaceae, Penaeaceae, Myrtaceae, and Onagraceae) and 54 species of melastomes. The sample represents 42 of the family's currently recognized ;150 genera, the 13 traditional tribes, and the three subfamilies, Astronioideae, Melastomatoideae, and Memecyloideae (5 Memecylaceae DC.). Parsimony and ML yield congruent topologies that place Memecy- laceae as sister to Melastomataceae. Pternandra, a Southeast Asian genus of 15 species of which ®ve were sampled, is the ®rst- branching Melastomataceae. This placement has low bootstrap support (72%), but agrees with morphological treatments that placed Pternandra in Melastomatacaeae because of its acrodromal leaf venation, usually ranked as a tribe or subfamily. The interxylary phloem islands found in Memecylaceae and Pternandra, but not most other Melastomataceae, likely evolved in parallel because Pternandra resembles Melastomataceae in its other wood characters. -
1 Updates Required to Plant Systematics: A
Updates Required to Plant Systematics: A Phylogenetic Approach, Third Edition, as a Result of Recent Publications (Updated June 13, 2014) As necessitated by recent publications, updates to the Third Edition of our textbook will be provided in this document. It is hoped that this list will facilitate the efficient incorporation new systematic information into systematic courses in which our textbook is used. Plant systematics is a dynamic field, and new information on phylogenetic relationships is constantly being published. Thus, it is not surprising that even introductory texts require constant modification in order to stay current. The updates are organized by chapter and page number. Some require only minor changes, as indicated below, while others will require more extensive modifications of the wording in the text or figures, and in such cases we have presented here only a summary of the major points. The eventual fourth edition will, of course, contain many organizational changes not treated below. Page iv: Meriania hernandii Meriania hernandoi Chapter 1.

Botany News. 2. May 20, 2020 California Academy of Sciences Tristemma mauritianum (A Madagascar Princess Flower) F. Almeda Hello to our volunteers, We celebrated a milestone this month. It has been 15 years since Deb Trock (Director of Collections and Botany Collections Manager) joined the Academy! We held a surprise party for her online--she was expecting a boring meeting and instead she was greeted with home-made signs saying congratulations (one of the fancier ones is below), many smiling faces, and speeches recognizing her contributions to the Academy collections and to the staff. We would have preferred sharing this special moment with her in-person, but we are adapting and enjoying the time that we can spend together virtually. We hope you enjoy our second newsletter, and we hope you are all keeping well and busy. With our best wishes from the Botany Department A Walk Through the Orchids in San Francisco Tom Daniel During my walk home from the Academy through four or five different neighborhoods on the west side of San Francisco, I see several different large-flowered and brightly colored orchids that residents have in their yards, porches, and windows. For the past few years, I have been growing a beautiful orchid in a bark-filled pot in my backyard. Our department’s research associate and orchid specialist, De Mally, gave Mary and me a cluster of pseudobulbs of Maxillaria soconuscana (recently transferred to a different genus, as Psittacoglossum soconuscanum), a native of Chiapas, Mexico that former botany curator Dennis Breedlove collected in 1986, and which she and Dennis described as new to science in 1989. -
The Systematic Distribution of Vascular Epiphytes: an Update
Selbyana 9: 2-22 THE SYSTEMATIC DISTRIBUTION OF VASCULAR EPIPHYTES: AN UPDATE w. JOHN KREss Marie Selby Botanical Gardens, 811 South Palm Avenue, Sarasota, Florida 33577 ABSTRACT. The list of vascular plant families and genera containing epiphytic species published by Madison (1977) is updated here. Ten percent (23,456 species) of all vascular plant species are epiphytes. Seven percent (876) of the genera, 19 percent (84) of the families, 45 percent (44) of the orders and 75 percent (6) of the classes contain epiphytes. Twenty-three families contain over 50 epiphytic species each. The Orchidaceae is the largest family of epiphytes, containing 440 epiphytic genera and 13,951 epiphytic species. Forty-three genera of vascular plants each contain over 100 epiphytic species. In 1977 Madison published a list of the vas those plants that normally spend their entire life cular plant families and genera that contain epi cycle perched on another plant and receive all phytic species.
