The present paper is based on the results of taxonomic research work conducted in Dera Ismail Khan District of KPK, Pakistan, during 2005 - 2007. The area was extensively surveyed in order to collect floating aquatic weeds. From the study area 11 floating aquatic weed species belonging to 9 genera and 9 families were collected and identified in the light of available literature. These plants include Bryophytes: 1 species, Ricciocarpus natans (L.) Corda; Pteridophytes: 2 species, Azolla pinnata R.Br. and Marselia quadrifolia L., and Spermatophytes: 8 species, Lemna aequinoctialis Welw., L. gibba L., Marselia quadrifoliata L. Nelumbo nucifera Gaerth., Nymphoides cristata (Roxb.) O. Ketze. Nymphoides indica (L.) Kuntze:, Pistia stratiotes L. Potamogeton nodosus Poiret and Spirodela polyrrhiza (L.) Schleid. Floating weeds on one hand cause serious problems and on the other hand they are used for various purposes. Data inventory consists of botanical name, family, major group, habit and habitat, flowering period, availability, distribution in D.I.Khan, Pakistan and world, beneficial and harmful effects. Key to the floating aquatic species of the area was developed for easy and correct identification and differentiation.
本文基于2005年至2007年期间在巴基斯坦开伯尔-普赫图赫瓦省德拉伊斯梅尔汗地区开展的分类学研究工作成果。为收集漂浮水生杂草,对该地区进行了广泛调查。根据现有文献,从研究区域收集并鉴定出了9科9属的11种漂浮水生杂草。这些植物包括苔藓植物:1种,浮苔(Ricciocarpus natans (L.) Corda);蕨类植物:2种,满江红(Azolla pinnata R.Br.)和四叶苹(Marselia quadrifolia L.),以及种子植物:8种,小浮萍(Lemna aequinoctialis Welw.)、紫萍(L. gibba L.)、四叶苹(Marselia quadrifoliata L.)、莲(Nelumbo nucifera Gaerth.)、荇菜(Nymphoides cristata (Roxb.) O. Ketze.)、金银莲花(Nymphoides indica (L.) Kuntze)、大薸(Pistia stratiotes L.)、穗状狐尾藻(Potamogeton nodosus Poiret)和多根紫萍(Spirodela polyrrhiza (L.) Schleid.)。漂浮杂草一方面会引发严重问题,另一方面又有多种用途。数据清单包括植物学名、科、主要类群、习性与栖息地、花期、可获得性、在巴基斯坦德拉伊斯梅尔汗地区及世界的分布、有益和有害影响。为便于准确识别和区分该地区的漂浮水生物种,编制了检索表。
