Atoll Research Bulletin No. 503 the Vascular Plants Of
ATOLL RESEARCH BULLETIN NO. 503 THE VASCULAR PLANTS OF MAJURO ATOLL, REPUBLIC OF THE MARSHALL ISLANDS BY NANCY VANDER VELDE ISSUED BY NATIONAL MUSEUM OF NATURAL HISTORY SMITHSONIAN INSTITUTION WASHINGTON, D.C., U.S.A. AUGUST 2003 Uliga Figure 1. Majuro Atoll THE VASCULAR PLANTS OF MAJURO ATOLL, REPUBLIC OF THE MARSHALL ISLANDS ABSTRACT Majuro Atoll has been a center of activity for the Marshall Islands since 1944 and is now the major population center and port of entry for the country. Previous to the accompanying study, no thorough documentation has been made of the vascular plants of Majuro Atoll. There were only reports that were either part of much larger discussions on the entire Micronesian region or the Marshall Islands as a whole, and were of a very limited scope. Previous reports by Fosberg, Sachet & Oliver (1979, 1982, 1987) presented only 115 vascular plants on Majuro Atoll. In this study, 563 vascular plants have been recorded on Majuro. INTRODUCTION The accompanying report presents a complete flora of Majuro Atoll, which has never been done before. It includes a listing of all species, notation as to origin (i.e. indigenous, aboriginal introduction, recent introduction), as well as the original range of each. The major synonyms are also listed. For almost all, English common names are presented. Marshallese names are given, where these were found, and spelled according to the current spelling system, aside from limitations in diacritic markings. A brief notation of location is given for many of the species. The entire list of 563 plants is provided to give the people a means of gaining a better understanding of the nature of the plants of Majuro Atoll. -

Speciation of Sehismatoglottis okadae (Araceae), an Adaptation to the Rheophytic Habitat of Mountain Stream in Sumatra Hiroshi OKADA and Mitsuru HoTTA ABSTRACT Schismatoglottis okadae, a rheophytic species, was investigated on its distribu- tion pattem, habitat, morphology, karyotype and population structure. The species is restricted to a few locations in West Sumatra which are separated from each other. In these places (locations) the species occurs only in the ai'ea near the stream. The stem and leaf show mat-rooted characteristic which is typical to other rheophytes. The chromosome number is 2n==26+O.-8B. But, one structural mutation of chromosome is present and it can be applied for the analysis of colony structurejust as the presence or absence of B-chromosomes. As the results, two kinds of colony structure have been detected: one is composed of homogeneous individuals, which seems to have propagated vegetatively, and the other is heterogeneous which would have developed from seedlings. The speciation of the group in the Barisan range is presumed to occur through the follow- ing' processes: the geographical upheaval of the Barisan range provided the new ecological niche, rapid streams, for the rheophytic forms. -
Studies on the Araceae of Sulawesi I: New Taxa of Schismatoglottis and Homalomena, and a Preliminary Checklist and Keys for Sulawesi

C. Boyce and Homalomena vittifolia Kurniawan & P. C. Boyce are described and illustrated as a new species from Sulawesi. Recognition of these novelties takes the aroid flora of Sulawesi to 41 species of which 15 (> 35%) are endemic. None of the 17 recorded genera are endemic, and one (Colocasia) is non-indigenous. Two species occur as adventives (Alocasia macrorrhi- zos and Amorphophallus paeoniifolius), and one (Colocasia esculenta) occurs semi-naturalized as an escape from cultivation as a carbohydrate crop. A preliminary checklist of the Araceae of Sulawesi is of- fered, and keys to the genera, and to the Sulawesi species of Schismatoglottis and Homalomena, are pre- sented.

Borneo and Its Disproportionately Large Rheophytic Aroid Flora
Gardens’ Bulletin Singapore 71(Suppl. 2):497-524. 2019 497 doi: 10.26492/gbs71(suppl. 2).2019-24 Borneo and its disproportionately large rheophytic aroid flora P.C. Boyce1 & S.Y.

[email protected] ABSTRACT. On the basis of decades of field observations and multidisciplinary research, in particular directed at species of Araceae exhibiting rheophytism, we offer an overview of morphological diversity among the more than 130 aroid species so adapted on Borneo. Based on a combination of morphological and concomitant ecological occurrence, a preliminary scheme of subcategories of van Steenis’ “rheophytic landplants” is outlined with the purpose of encouraging study to better understand the impetus of obligate rheophytic aroids’ evolution. It is hoped that the proposed subcategories will encourage targeted research with abundant field-based observations. Criticism is directed at the current demand by scientific journals that computer algorithm-generated statistical ‘proof’ be provided for all observational life science writing and further insisting that all such observations be linked to a ‘big picture’ by comparison within the context of a global perspective, preferably incorporating whatever themes are currently fashionable in the field. Such requirements discourage researchers, and particularly students, from undertaking purely observational research, and effectively result in the suppression of publication of vital observational data while encouraging publication of statistically well-supported biological nonsense. -
History and Current Status of Systematic Research with Araceae
HISTORY AND CURRENT STATUS OF SYSTEMATIC RESEARCH WITH ARACEAE Thomas B. Croat Missouri Botanical Garden P. O. Box 299 St. Louis, MO 63166 U.S.A. Note: This paper, originally published in Aroideana Vol. 21, pp. 26–145 in 1998, is periodically updated onto the IAS web page with current additions. Any mistakes, proposed changes, or new publications that deal with the systematics of Araceae should be brought to my attention. Mail to me at the address listed above, or e-mail me at [email protected]. Last revised November 2004 INTRODUCTION The history of systematic work with Araceae has been previously covered by Nicolson (1987b), and was the subject of a chapter in the Genera of Araceae by Mayo, Bogner & Boyce (1997) and in Curtis's Botanical Magazine new series (Mayo et al., 1995). In addition to covering many of the principal players in the field of aroid research, Nicolson's paper dealt with the evolution of family concepts and gave a comparison of the then current modern systems of classification. The papers by Mayo, Bogner and Boyce were more comprehensive in scope than that of Nicolson, but still did not cover in great detail many of the participants in Araceae research. In contrast, this paper will cover all systematic and floristic work that deals with Araceae, which is known to me. It will not, in general, deal with agronomic papers on Araceae such as the rich literature on taro and its cultivation, nor will it deal with smaller papers of a technical nature or those dealing with pollination biology. -
05-F Historical and Taxonomic Review of Homalomena.Indd
Gardens’ Bulletin Singapore 62 (2): 277–289. 2011 277 Studies on Homalomeneae (Araceae) of Peninsular Malaysia II: An historical and taxonomic review of the genus Homalomena (excluding Chamaecladon) Kiaw Kiaw Ng, P.C. Boyce1 and S. Othman Pusat Pengajian Sains Kajihayat (School of Biological Sciences), Universiti Sains Malaysia, 11800 USM, Pulau Pinang, Malaysia [email protected] (corresponding author) ABSTRACT. An historical and taxonomic review of Homalomena (excluding species assigned to the Chamaecladon Supergroup sensu Boyce & Wong) for Peninsular Malaysia is presented. Five species are recognised of which one, H. truncata (Schott) Hook.f. represents a new species record for the Peninsula. Keys to the Peninsular Malaysian Supergroups and species, and a taxonomic conspectus, are provided. Three species are illustrated from living plants, and H. wallichii from the type specimen. Keywords. Araceae, Homalomena, Supergroup, Peninsular Malaysia Introduction Recent publications on Asian Homalomena have focussed on Papuasia (Hay 1999, Herscovitch & Hay 2003) and East Sunda (Hay & Herscovitch 2002; Boyce & Wong 2008, 2009; Boyce, Wong & Fasihuddin 2010). Until recently, apart from ad hoc descriptions of new taxa (Baharuddin & Boyce 2005, 2009), little attention has been paid to the genus in Peninsular Malaysia. Apart from Ridley’s adequate but now out- dated account (1925), the only complete review is that of Furtado (1939), an account marred not least by poor and often confused species’ delimitation. Hay (1999) provided a concise taxonomic and nomenclatural historical review of Homalomena in Papuasia. More recently, Boyce & Wong (2008) and Ng et al. (in press) proposed and elaborated informal supergoups and species complexes as a tool to aid taxonomic study of this speciose and taxonomically ill-understood genus. -

All vascular plants were enumerated and identified. Importance value index (IVI) was computed to characterize the floristic composition. To capture different aspects of species diversity, we considered five different indices. The mean stem density was 7585 stems per ha. In total 36797 vascular plants representing 348 species belong to 227 genera in 89 families were identified within 5-ha of a coastal hill forest that is comprises 4.2% species, 10.7% genera and 34.7% families of the total taxa found in Peninsular Malaysia. Based on IVI, Agrostistachys longifolia (IVI 1245), Eugeissona tristis (IVI 890), Calophyllum wallichianum (IVI 807), followed by Taenitis blechnoides (IVI 784) were the most dominant species. The most speciose rich families were Rubiaceae having 27 species, followed by Dipterocarpaceae (21 species), Euphorbiaceae (20 species) and Palmae (14 species). According to growth forms, 57% of all species were trees, 13% shrubs, 10% herbs, 9% lianas, 4% palms, 3.5% climbers and 3% ferns. -
