  • Northwest Highlands Bioregion Technical Descriptions
    Department of Environment and Science Regional Ecosystem Technical Descriptions Technical descriptions provide a detailed description of the full range in structure and floristic composition of regional ecosystems (e.g. 1.1.10) and their component vegetation communities (e.g. 1.11.10a, 1.11.10b). The descriptions are compiled using site survey data from the Queensland Herbarium’s CORVEG database. Distribution maps, representative images (if available) and the pre-clearing and remnant area (hectares) of each vegetation community derived from the regional ecosystem mapping (spatial) data are included. The technical descriptions should be used in conjunction with the fields from the regional ecosystem description database (REDD) for a full description of the regional ecosystem. Quantitative site data from relatively undisturbed sites are extracted from CORVEG and summarized to provide information specific to each vegetation community. Technical descriptions include the attributes: tree canopy height and cover and native plant species composition of the predominant layer, which are used to assess the remnant status of vegetation under the Vegetation Management Act 1999. However, as technical descriptions reflect the full range in structure and floristic composition across the climatic, natural disturbance and geographic range of the regional ecosystem, local reference sites should be used where possible (Neldner et al. 2005 section 3.3.3). The technical descriptions are subject to review and are updated as additional data becomes available.

  • A New Species and Hybrid in the St Helen a Endemic Genus Trochetiopsis
    EDINB. 1. BOT. 52 (2): 205-213 (1995) 205 A NEW SPECIES AND HYBRID IN THE ST HELEN A ENDEMIC GENUS TROCHETIOPSIS Q. C. B. CRONK * The discovery in historic herbaria of an overlooked extinct endemic from the island of St Helena is reported. The first descriptions of St Helena Ebony, Trochetiopsis melanoxylon (Sterculiaceae), and the specimens associated with them in the herbaria of Oxford University (OXF) and the Natural History Museum, London (BM), do not match living and later-collected material, and instead represent an extinct plant. A new name is therefore needed for living St Helena Ebony: Trochetiopsis ebenus Cronk sp. nov. The hybrid between this species and the related T erythroxylon is also described here: Trochetiopsis x benjamini Cronk hybr. nov. (Sterculiaceae), and chromosome counts of 2n =40 are reported for the hybrid and both parents for the first time. The re-assessment of the extinct ebony emphasizes the importance of historic herbarium collections for the study of species extinction. INTRODUCTION In 1601 and 1610, at the beginning and end of his voyage to the East Indies, Franvois Pyrard de Laval touched at St Helena, an isolated island in the South Atlantic Ocean. He wrote: 'Sur Ie haut de la montagne il y a force arbre d'Ebene, et de bois de Rose' (Pyrard, 1679; Gray, 1890) - the first mention in print of species of Trochetiopsis (i.e. St Helena Redwood and St Helena Ebony). The island was settled in 1659, and the settlers of the English East India Company immediately put these ecologically important species to use.

Email: [email protected] Table S1 (below) comprises a list of seed producing genera occurring in rainforest in Australia and various island groups in the South Pacific, along with any available information on the seed storage behaviour of species in those genera. Note that the list of genera is not exhaustive and the absence of a genus from a particular island group simply means that no reference was found to its occurrence in rainforest habitat in the references used (i.e. the genus may still be present in rainforest or may occur in that locality in other habitats). As the definition of rainforest can vary considerably among localities, for the purpose of this paper we considered rainforests to be terrestrial forest communities, composed largely of evergreen species, with a tree canopy that is closed for either the entire year or during the wet season.

  • Seed Morphology and Its Taxonomic Significance in the Family Malvaceae
    Pak. J. Bot., 48(6): 2307-2341, 2016. SEED MORPHOLOGY AND ITS TAXONOMIC SIGNIFICANCE IN THE FAMILY MALVACEAE RUBINA ABID*, AFSHEEN ATHER AND M. QAISER Department of Botany, University of Karachi, Karachi-75270, Pakistan *Corresponding author’s email: [email protected] Abstract The seed morphological studies of 75 taxa belonging to 6 sub-families of the family Malvaceae were carried out from Pakistan. In Pakistan the family Malvaceae is represented by 6 sub-families viz., Byttnerioideae, Dombeyoideae, Malvoideae, Bombacoideae, Helicteroideae and Sterculioideae. The seed macro and micro morphological characters are examined, using light (LM) and scanning electron microscopy (SEM). Detailed seed morphological descriptions, micrographs and keys based on seed characters are also provided. A variety in various quantitative and qualitative seed characters was observed. The micro-morphological characters of seeds are quite significant to strengthen the taxonomic decisions within the family Malvaceae at various levels. The data obtained from the seed morphological characters were analyzed numerically to trace out the phylogenetic affinities for the taxa within the family Malvaceae from Pakistan. Key words: Malvaceae, Seeds, Pakistan. Introduction (Nikon XN Model) and scanning electron microscope (JSM- 6380A).

  • A CHECK LIST of PLANTS RECORDED in TSAVO NATIONAL PARK, EAST by P
    Page 169 A CHECK LIST OF PLANTS RECORDED IN TSAVO NATIONAL PARK, EAST By P. J. GREENWAY INTRODUCTION A preliminary list of the vascular plants of the Tsavo National Park, Kenya, was prepared by Mr. J. B. Gillett and Dr. D. Wood of the East African Herbarium during 1966. This I found most useful during a two month vegetation survey of Tsavo, East, which I was asked to undertake by the Director of Kenya National Parks, Mr. P. M. Olindo, during "the short rains", December-January 1966-1967. Mr. Gillett's list covered both the East and West Tsavo National Parks which are considered by the Trustees of the Kenya National Parks as quite separate entities, each with its own Warden in Charge, their separate staffs and organisations. As a result of my two months' field work I decided to prepare a Check List of the plants of the Tsavo National Park, East, based on the botanical material collected during the survey and a thorough search through the East African Herbarium for specimens which had been collected previously in Tsavo East or the immediate adjacent areas. This search was started in May, carried out intermittently on account of other work, and was completed in September 1967. BOTANICAL COLLECTORS The first traveller to have collected in the area of what is now the Tsavo National Park, East, was J. M. Hildebrandt who in January 1877 began his journey from Mombasa towards Mount Kenya. He explored Ndara and the Ndei hills in the Taita district, and reached Kitui in the Ukamba district, where he spent three months, returning to Mombasa and Zanzibar in August.

H. GAWHARI1, 2, STEPHEN L. JURY 2 & ALASTAIR CULHAM 2 1 Botany Department, Cyrenaica Herbarium, Faculty of Sciences, University of Benghazi, Benghazi, Libya E-mail: [email protected] 2 University of Reading Herbarium, The Harborne Building, School of Biological Sciences, University of Reading, Whiteknights, Read- ing, RG6 6AS, U.K. E-mail: [email protected]. E-mail: [email protected]. Abstract The Libyan flora was last documented in a series of volumes published between 1976 and 1989. Since then there has been a substantial realignment of family and generic boundaries and the discovery of many new species. The lack of an update or revision since 1989 means that the Libyan Flora is now out of date and requires a reassessment using modern approaches. Here we report initial efforts to provide an updated checklist covering 43 families out of the 150 in the published flora of Libya, including 138 genera and 411 species. Updating the circumscription of taxa to follow current classification results in 11 families (Coridaceae, Guttiferae, Leonticaceae, Theligonaceae, Tiliaceae, Sterculiaceae, Bombacaeae, Sparganiaceae, Globulariaceae, Asclepiadaceae and Illecebraceae) being included in other generally broader and less morphologically well-defined families (APG-IV, 2016). As a consequence, six new families: Hypericaceae, Adoxaceae, Lophiocarpaceae, Limeaceae, Gisekiaceae and Cleomaceae are now included in the Libyan Flora.

Little more than a year has elapsed since the “ Gardener's Library ” commenced, and if we may judge from the flattering reception this Volume on the many Failures incident to the best managed Flower Gardens has already met with, it might be said that we have, at least in some degree, met the general wants of the present age. It cannot be doubted but, to many of our scientific readers, various errors in the histories of the different insects will be will observed ; should such be the case, we trust they consider these decrepancies as consequent on our imperfect observations as plain practical will received Gardeners ; and any corrections be with thankfulness.

Specht (Corresponding author) Emeritus Professor of Botany, The University of Queensland, Brisbane, QLD 4072, Australia E-mail: [email protected] Eugene J. Moll Department of Biodiversity and Conservation Biology, University of the Western Cape, Bellville, South Africa Received: June 30, 2014 Accepted: July 13, 2014 Published: October 14, 2014 doi:10.5296/jee.v5i2.6446 URL: http://dx.doi.org/10.5296/jee.v5i2.6446 Abstract During the short season of annual shoot growth, Foliage Projective Covers (FPCs) in both overstorey and understorey strata, coupled with leaf attributes (Leaf Specific Weight, Leaf Area), are determined by aerodynamic fluxes flowing over and through the plant community. These parameters determined the Evaporative Coefficient — the monthly ratio of actual to potential evapotranspiration per mm of available soil moisture. Maximal FPC is produced in habitats supplied with optimal soil moisture during this short season of shoot growth. Vertical growth of foliage shoots — the number of leaves per shoot and internode lengths — is determined in relation with available soil water and soil nutrients (especially phosphorus and nitrogen ions) during this seasonal growth. Ambient temperature is similarly concerned. The Leaf Area Index (area of all leaves per hectare) determines the interception of solar radiation — and hence net photosynthesis per hectare per annum. This energy-fixation by overstorey foliage determines the yearly growth of the producer, consumer and decomposer sections of the ecosystem. In turn, the biodiversity (number of species per hectare) of producers and resident consumers is determined.
