I wish to express my sincere gratitude to Mr. Andy Graham, Head of Wetlands for People of WWT for providing us opportunity to complete the hydrologic and vegetation investigation in the two wetlands. We express enormous thanks to Robert Van Zalinge - Cambodian Lower Mekong Wetlands Project Technical Advisor - with his abundantly help and we ogether went through a sweaty field work. Especially, this report would not have been possible without the enthusiastic support of him. Last but certainly not least we would like express our sincere thanks to Mr. Seng Kim Hout, National Project Manager for guidance of field works.

  • Appendix Color Plates of Solanales Species
    Appendix Color Plates of Solanales Species The first half of the color plates (Plates 1–8) shows a selection of phytochemically prominent solanaceous species, the second half (Plates 9–16) a selection of convol- vulaceous counterparts. The scientific name of the species in bold (for authorities see text and tables) may be followed (in brackets) by a frequently used though invalid synonym and/or a common name if existent. The next information refers to the habitus, origin/natural distribution, and – if applicable – cultivation. If more than one photograph is shown for a certain species there will be explanations for each of them. Finally, section numbers of the phytochemical Chapters 3–8 are given, where the respective species are discussed. The individually combined occurrence of sec- ondary metabolites from different structural classes characterizes every species. However, it has to be remembered that a small number of citations does not neces- sarily indicate a poorer secondary metabolism in a respective species compared with others; this may just be due to less studies being carried out.

Austin Arizona-Sonora Desert Museum, 2021 North Kinney Road, Tucson, AZ 85743, USA Received 23 October 2007; received in revised form 28 January 2008; accepted 29 January 2008 Available online 12 February 2008 Abstract People in the Indian region often apply shankhapushpi and vishnukranti, two Sanskrit-based common names, to Evolvulus alsinoides. These are pre-European names that are applied to a medicinal American species transported into the area. The period of introduction is uncertain, but probably took place in the 1500s or 1600s. Examination of relationships of Evolvulus alsinoides, geographic distribution, its names in Asia, medical uses, and chemical and laboratory analysis indicates that the alien plant was adopted, given an ancient Indian name, and incorporated into some Old World pharmacopoeias. The herb apparently was included in medicines because it not only reminded people of certain aspects of their gods and goddesses, but also because the chemicals it contained were useful against some maladies.

Sasirangan industries produce large amount of wastewater, which then is directly discarded around the environment without treatment processes. The effect afterward is the oxygen supply in the water diminishes and eventually triggers the activity of anoxic-anaerobic microorganisms that produces odors. Constructed wetlands are able to become the alternative to waste treatment technology at the economical household scale industries. This study was conducted to determine the ability of the removal of BOD and COD in the sasirangan effluent with constructed wetlands (CW) surface flow system using the batch method. Plants used in CW is Hydrilla verticillata, purun tikus (Eleocharis dulcis) and lotus (Nelumbo nucifera). CW was running for 0, 3, 6, 9 and 12 days.

CHANDRASENA Dtyartment of Botany, University of Colombo, P. 0. Box 1490, Colombo 3, Sri Lanka. (Date of receipt : 24 Februar-y 1989) (Date of acceptance : 09 August 1989) Abstract: A survey of rice-field weeds was carried out in the Districts of Ratnapura and ~urunegaladuring the 'Yala' and 'Maha' seasons of 1986. Two hundred and thirty four fields of the Ratnapura District and 196 fields of the Kurunegala District were sampled at a time when the rice was at heading to flowering and farmers had carried out weeding or herbicide applications for weed control. One hundred and forty seven species of weeds belonging to 95 genera and 37 plant families were recor- ded from the two districts, indicating a vcry rich diversity in thc weed-flora. Of thcse, 38 species occurred in less than 10% of the fields ;65 species in 10-20% of the fields and 44 species in 20% or more fields. By far the commonest and problematic wceds were monocotylcdons of the families Poaceae (Gramineae) and Cyperaceae. Tl11.e~grass spccies Echirrochloa crirs-galli (L.)Beauv., Echinochloa cotanurn (L.)
