Located on McKinnon Creek, in the headwaters of Wrights Creek, this is a very accessible short walk located in beautiful rainforest at the foot of the Lamb Range. We had a great turnout for the first walk of the year, and were pleased to be joined by Val Carnie, Ing Toh and Nicole Kenyon as well as the regulars. The rainforest was relatively cool and shady, a pleasant contrast to the extreme heat and humidity of nearby suburbia. The rainforest here is a “complex notophyll vine forest”, typical of the hillslopes around Cairns. Canopy species we saw included Terminalia microcarpa (damson), Chisocheton longistipitatus, Cryptocarya hypospodia (northern walnut), Elaeocarpus grandis (quandong) and Castanospora alphandii (brown tamarind). In the shadowed understorey of this forest grow two interesting plants. One of these, Corymborkis veratrifolia (cinnamon orchid), we were privileged to catch in flower. The other, Acalypha lyonsii is extremely rare, found only on the Cairns hillslopes west of Edmonton and Redlynch. This attractive small shrub has proved amenable to cultivation, and can be seen in some of the more tasteful gardens around town. After our walk, we all sat down for a drink and Mary's home-made biscuits (thanks Mary). With it's proximity to Cairns, pleasant creek and tall rainforest, Isabella Falls was a very pleasant way to start off 2016.

ABSTRACT The Lower Gangetic Plains particularly from Dakhineshwar to Uluberia, West Bengal was investigated for the taxonomic and ecological analyses of its naturalized vegetation. The physicochemical studies of soil were also performed from this site. It was observed mangrove plants prevailed at zones where higher percentage of silt was present, while inland plants were grown where percentage of sand and clay were higher. A total of 95 plant species were recorded and their phytoclimatic study was done and the result revealed that percentage of phanerophytes was maximum among others. From phytosociological study it was observed that mangrove associates such as Cryptocoryne ciliata and Oryza coarctata showed highest IVI values, on the other hand Cynodon dactylon was dominated at non-mangrove site. The present analyses indicated existence of two distinct plant communities in the site with more or less stable vegetation pattern. Keywords: Lower Gangetic Plain, vegetation, diversity, community *Corresponding author May–June 2017 RJPBCS 8(3) Page No. 1558 ISSN: 0975-8585 INTRODUCTION Though India has a wide range of vegetation comprising of tropical rain forest, tropical deciduous forest, thorny forest, montane vegetation and mangrove forest, the Gangetic Plains in India form an important biogeographic zone in terms of vegetation characterized by fine alluvium and clay rich swamps, fertile soil and high water retention capacity.

Pruesapan3, I.R.H. Telford4, H.-J. Esser 5, J.J. Bruhl4 Key words Abstract Previous molecular phylogenetic studies indicated expansion of Breynia with inclusion of Sauropus s.str. (excluding Synostemon). The present study adds qualitative and quantitative morphological characters to molecular Breynia data to find more resolution and/or higher support for the subgroups within Breynia s.lat. However, the results show molecular phylogeny that combined molecular and morphological characters provide limited synergy. Morphology confirms and makes the morphology infrageneric groups recognisable within Breynia s.lat. The status of the Sauropus androgynus complex is discussed.

    BIODIVERSITY CONSERVATION ON THE TIWI ISLANDS, NORTHERN TERRITORY: Part 1. Environments and plants Report prepared by John Woinarski, Kym Brennan, Ian Cowie, Raelee Kerrigan and Craig Hempel. Darwin, August 2003 Cover photo: Tall forests dominated by Darwin stringybark Eucalyptus tetrodonta, Darwin woollybutt E. miniata and Melville Island Bloodwood Corymbia nesophila are the principal landscape element across the Tiwi islands (photo: Craig Hempel). i SUMMARY The Tiwi Islands comprise two of Australia’s largest offshore islands - Bathurst (with an area of 1693 km 2) and Melville (5788 km 2) Islands. These are Aboriginal lands lying about 20 km to the north of Darwin, Northern Territory. The islands are of generally low relief with relatively simple geological patterning. They have the highest rainfall in the Northern Territory (to about 2000 mm annual average rainfall in the far north-west of Melville and north of Bathurst). The human population of about 2000 people lives mainly in the three towns of Nguiu, Milakapati and Pirlangimpi. Tall forests dominated by Eucalyptus miniata, E. tetrodonta, and Corymbia nesophila cover about 75% of the island area. These include the best developed eucalypt forests in the Northern Territory. The Tiwi Islands also include nearly 1300 rainforest patches, with floristic composition in many of these patches distinct from that of the Northern Territory mainland. Although the total extent of rainforest on the Tiwi Islands is small (around 160 km 2 ), at an NT level this makes up an unusually high proportion of the landscape and comprises between 6 and 15% of the total NT rainforest extent. The Tiwi Islands also include nearly 200 km 2 of “treeless plains”, a vegetation type largely restricted to these islands.

Bogor, September 2012 Deden Mudiana NRP E351100121 ABSTRACT DEDEN MUDIANA. Diversity, Population Structure and Distribution Paterrn of Syzygium in Gunung Baung, East Java. Under the supervision of AGUS HIKMAT and DIDIK WIDYATMOKO The research of Syzygium diversity, its population structure and the distribution patterns were conducted in Gunung Baung Nature Park, East Java. A total of five block locations, each comprising five transect sections, were purposively selected to obtain data of the taxon diversity, population stucture and distribution patterns. The importance value index, the individual number of each stratum (stage class) (i.e. seedlings, saplings, poles and trees) and variance-to-mean ratio were calculated. The principal component analysis, cluster analysis, multiple linear regressions and canonical correspondence analysis were performed to determine the relationships between abiotic and biotic factors in regard with the presence of Syzygium. There were six species of Syzygium in Gunung Baung, Pasuruan, namely S. cumini, S. polyanthum, S. littorale, S. pycnanthum, S. racemosum, and S. samarangense. The population structure of Syzygium varied considerably, only S.
