Floristic Patterns in Coastal Rainforest of Shoalwater Bay, Central Queensland
362 Cunninghamia 8(3): 2004 McCarthy et al., Floristic patterns in coastal rainforest of Shoalwater Bay Floristic patterns in coastal rainforest of Shoalwater Bay, Central Queensland Peter McCarthy1, Peter Clarke2 and Jeremy Bruhl3 113 Knox St., Clovelly NSW 2031; 2Botany, School of Environmental Sciences and Natual Resources Management, University of New England, Armidale, NSW 2351, AUSTRALIA; 3Botanic Gardens and Domain Trust, Mrs Macquaries Rd, Sydney NSW 2000, AUSTRALIA. Abstract: A study was undertaken of the floristic patterns in coastal rainforest (low closed forest) of Shoalwater Bay, central Queensland. The site encompasses 60 km of coastline, extending from latitude 22° 08’ 30’’ to 22° 30’ 0” and longitude 150° 02’ 00” to 150° 24’ 30”. The rainforest grows on coastal Holocene sand dunes, swales and sand flats, distributed as a series of 27 discrete patches greater than one hectare along 60 kilometres of coastline. Mean patch size was 10.7 hectares (maximum 150 hectares). The flora was predominantly woody, and lacked the complex growth forms of Webb (1968). Floristic links with central and north Queensland were strong, with some species distributions extending into Malesia and the Pacific. Three physical strata, emergent (composed of trees), canopy (composed of trees, vines and epiphytes) and sub-canopy (trees, vines and herbs) were recognised. The herb layer was very poorly developed. Eighty-one species were recorded, representing 42 families and 72 genera. Sixty three quadrats were sampled across the rainforest patches to measure abundance of all vascular taxa using frequency score. Five floristic groups were defined from agglomerative classification analysis, one representing mixed forest, two representing low microphyll vine forest (LMVF) and two representing microphyll vine thicket (MVT).

Comparison of Different Classifications on the Celastraceae
UNITED STATES DEPARTMENT OF AGRICLJLTURE AGRICULTURAL RESEARCH SERVICE NORTHEASTERN REGlON AGRICULTURAL RESEARCH CENTER BELTSVILLE. MARYLAND 20705 Novenber 7, 1974 / Subject: ConpadSon of Different Classifications on the Celastraceae in Africa with Discussions on the Status of Gymnosporia and Other Genera To : R. E. Perdue, Jr., Chief ,.. Medicinal Plant Resources ~aboratory Currently, the taxonomy of the Celastraceae is in a state of confusion. A few recent revisions limited mostly ,to political boundaries, have helped to clarify the systematics in a few genera; however, the continued disagreement among generic relationships seems to make it nore difficult for the non-specialist. Because of special efforts to procure plant samples in this family, frequent synonomy has led to confusion as well as duplica- tion, especially in Africa where a number of samples have been received from floristically related countries in which different authorities are recogcized for the Celastracean Flora. This report, primarily, will 'deal with the systematic problems of the African Celasrrtseae. Until recently, the Hippocrateaceae was treated as a separate family from the Celastraceae (Smith, 1940; Loesener, 1942; Wilczek, 1960; Hallee, 1962). L Robson (1965, 1966), Ding Hou (1963, 1964), Blakelock (1958), and Codd (1972) have united the Hippocrateaceae with the Celastraceae; but, their reasons for uniting the two families are not in agreement. The Celastraceae is believed by Codd and Kobson to comprise about 60 to 70 genera, but Ding Hou has indicated that there are about 90 genera. For the purpose of identifying two major complexes, which taxonomists are not in agreement, I will refer to the Celastraceae and Hippocrateaceae as two separate families.

Accepted 18 November, 2011 This study aimed to survey medicinal plants in mangrove and beach forests from Sating Phra Peninsula, Songkhla Province. Three representative districts including Sing Ha Nakhon, Sating Phra and Ranode were selected. Semi-structured interview was conducted to six local healers for asking about local names, parts of use, preparation and properties. Plant specimens also were collected. Identification was done and the specimens were deposited at The Prince of Songkla University herbarium (PSU). A total of 110 species belonging to 100 genera and 51 families was found. Among them, 69 species were only found in the beach forests, 35 species were only found in the mangrove forests and 6 species could be found in both areas. Fabaceae was the most important family in term of species used. Herb was the most frequently used habit of plants. Most plant species were used for curing fever (18.52%), skin diseases (10.65%) and gastrointestinal tract problems (10.19%), respectively. Interestingly, 34 species relate to pharmacological activities, while 13 species have never been investigated. Therefore, their biological activity should be investigated to support utilization of herbal medicine.

International Union for Conservation of Nature, Sri Lanka Country Office i Occasional Papers of IUCN Sri Lanka The role of IUCN Sri Lanka embodies the overall mission of the International Union for the Conservation of Nature: to help nations throughout the world to protect and use sustainably their natural resources for the benefit of all their people. In serving this mission, IUCN Sri Lanka aims to contribute towards the development and implementation of appropriate conservation policies, based on scientific information in the field of nature conservation. The Occasional Paper series reports on the outcomes of research and project work conducted by IUCN staff and their collaborators, covering a wide range of subjects related to conservation – from biodiversity assessments to participatory conservation approaches. This objective of the present Occasional Paper series is to share these lessons learnt from the wealth of field experience, amongst a wider audience and to provide scientific information relevant to conservation action. The papers will be kept simple and non-technical. It is intended that the series will contribute towards conservation action and will be used extensively by policy makers, managers of natural resources, researchers, students and the public at large.

Abstract: A study was undertaken of the floristic patterns in coastal rainforest (low closed forest) of Shoalwater Bay, central Queensland. The site encompasses 60 km of coastline, extending from latitude 22° 08’ 30’’ to 22° 30’ 0” and longitude 150° 02’ 00” to 150° 24’ 30”. The rainforest grows on coastal Holocene sand dunes, swales and sand flats, distributed as a series of 27 discrete patches greater than one hectare along 60 kilometres of coastline. Mean patch size was 10.7 hectares (maximum 150 hectares). The flora was predominantly woody, and lacked the complex growth forms of Webb (1968). Floristic links with central and north Queensland were strong, with some species distributions extending into Malesia and the Pacific. Three physical strata, emergent (composed of trees), canopy (composed of trees, vines and epiphytes) and sub-canopy (trees, vines and herbs) were recognised. The herb layer was very poorly developed. Eighty-one species were recorded, representing 42 families and 72 genera. Sixty three quadrats were sampled across the rainforest patches to measure abundance of all vascular taxa using frequency score. Five floristic groups were defined from agglomerative classification analysis, one representing mixed forest, two representing low microphyll vine forest (LMVF) and two representing microphyll vine thicket (MVT).
