This climate variation（4） contribute（5） to the enormous（6） diversity（7） of plant life in Australia, including Rainforests, Woodlands, Grass and Scrublands, Sclerophyll Forests both wet and dry, Coastal Heathlands, Alpine Forests, Saltbush, Mallee and Aquatic plants as well.

由于气候的差异，使得澳洲拥有多样的植物生态，包括雨林、森林、草原以及矮灌丛区、干湿型地中海硬叶森林群系、沼泽、海岸荒地、高山林、盐丛林、桉树灌丛以及水生植物等。

In this article,Canna,Cyperus and Penisetum were grown in artificial solution contained heavy metals such as lead and chromium to investigate their endurance to the two kinds of heavy metal.The experiment results showed that lead and chromium could decrease the height and biomass of plants even at low concentration of 2.0mg/L.

随着工业的迅速发展，各种工业废水和固体废弃物的渗出液直接排入水体，致使水体中重金属铅(Pb2+)和铬(Cr6+)等含量越来越高[1]，重金属不能像其他有机化合物那样可自然降解或生物降解，往往存在水体或沉积到水域底部或被水生植物浮游植物。

Quillworts are heterosporous, mainly aquatic perennials, with a dense rosette of tubular quill-like leaves arising from a short, stout rootstock.

水韭目的植物具有异型孢子，是多年水生植物。其管状条形叶密集簇生于粗短的根茎之上。

This study used floating macrophytes（Eichhornia crassipes,Pistia stratiotes,Lemna perpusilla and Salvinia natans） to remove the heavy metals from the prepared solution containing metal effectively.

摘要 水生植物具有吸收及累积重金属的特性，故本研究利用浮水性植物（布袋莲、大萍、青萍及槐叶苹）处理含重金属之溶液使其含量能有效降低。

The results of the 60 days experiment showed that both submersed macrophytes(Hydrilla verticillata,Potamogeton malaianus and Vallisneria natans) and floating-leaved macrophytes(Nymphoides indica and Trapa quadrispinosa)had very high removal rates for TN,TP,NO_3~——N and PO_4~——P,and the values exceeded 60%,but Potamogeton malaianus and Vallisneria natans were most effective at removing nutr...

结果表明，沉水植物马来眼子菜、苦草、轮叶黑藻和浮叶植物荇菜、菱等5种水生植物对水体的总氮、总磷、硝态氮和正磷酸盐都有较好的去除效果，去除率在60%以上，且以马来眼子菜和苦草的效果最好，去除率在80%以上。

It analysed the corresponding number of microorganisms quantitatively. The results shows that these three kinds of aquatic plants had different abilities in removing TN and TP. It also shows that different plants had different optimal treatments, but they could promote the growth of rhizobacteria. In comparison, Oenanthe javanica DC system.

结果表明，三种水生植物去除营养盐氮、磷的能力各有不同，在所设置的三个TN浓度下，各有一种植物能够达到最好的处理效果，且能较好地促进根际细菌的生长。

There are about 18000 species, which include herbs, trees, shrubs, climbers, and some aquatics.
