Jacquemontia Reclinata Grown in Containers

We conducted an experiment using potted seedlings grown without shade, or under low, KEY WORDS moderate, or heavy shade enclosures. Shade did not affect revegetation, coastal strand, propagation, light shoot growth, or leaf or stem dry mass. Plants subjected to all levels of shade, however, had 40% to 70% less root dry NOMENCLATURE mass and about 50% lower root-to-shoot ratios than non- ITIS (2002) shaded plants.

Biodiversitas 19: 140-152. Bogor Botanic Gardens is an ex-situ conservation centre, covering an area of 87 ha, with 12,376 plant specimens, collected from Indonesia and other tropical countries throughout the world. One of the richest collections in the Gardens comprises members of the aroid family (Araceae). The aroids are planted in several garden beds as well as in the nursery. They have been collected from the time of the Dutch era until now. These collections were obtained from botanical explorations throughout the forests of Indonesia and through seed exchange with botanic gardens around the world. Several of the Bogor aroid collections represent ‘living types’, such as Scindapsus splendidus Alderw., Scindapsus mamilliferus Alderw. and Epipremnum falcifolium Engl. These have survived in the garden from the time of their collection up until the present day. There are many aroid collections in the Gardens that have potentialities not widely recognised. The aim of this study is to reveal the diversity of aroids species in the Bogor Botanic Gardens, their scientific value, their conservation status, and their potential as ornamental plants, medicinal plants and food. -

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. -

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. -

WEISLER, JON C.HATHER AND DYLAN MORROW ISSUED BY NATIONAL MUSEUM OF NATURAL HISTORY SMITHSONIAN INSTITUTION WASHINGTON, D.C., USA. AUGUST 1999 b Pitcairn Group I( Gambier Group 0 e Oeno Henderson a 0 . Ducie Pitcairn THE NON-NATIVE VASCULAR PLANTS OF HENDERSON ISLAND, SOUTH-CENTRAL PACIFIC OCEAN STEVE WALDREN1, MARSHALL I. WEISLER2, JON G. HATHER3 AND DYLAN MORROW4 ABSTRACT Henderson island, a World Heritage Site in the Pitcairn group, south-central Pacific Ocean, has often been thought to have a pristine vegetation. Our archaeological investigations and field observations in 1991-1992, supported by recent observations in 1997, suggest the occurrence of former areas of Polynesian cultivation near to the North and East Beaches, and indicate that about 17 non-native vascular plant taxa have occurred. The majority of these were deliberate Polynesian introductions, some taxa are known only as sub-fossils from Polynesian occupation sites; some of this sub-fossil material may represent imported plant parts such as timber or food wraps, rather than indicating in situ cultivation. These Polynesian introductions show little spread from their probable site of introduction and are mostly restricted to the vicinity of the northern beaches; some have become extinct on Henderson. The Pitcaim islanders have also introduced a small number of vascular plants, and one of these (Passijora maliformis) is potentially invasive. Other taxa have been accidentally introduced, at least one by a recent scientific expedition in 1991. The intact nature of much of the native vegetation may have restricted the opportunities for more widespread colonization; care is needed to ensure that this situation persists.
