Leaves ovate-lanceolate to broadly lanceolate, base rounded, truncate, or semiclasping; plants typically sparsely to densely pubescent; epicalyx segments much longer than sepals.

离开卵状披针形到宽披针形，基部圆形，削去，或；通常的植株疏生到密被短柔毛；副萼片远长于萼片。 1 L。 salicaria 千屈菜

Floral tubes prominently undulate-winged from sinus of sepals, wings attenuate on pedicellate floral base; floral tubes densely white pubescent; epicalyx absent.

在有花梗身上从萼片，翅渐狭的凹缺波状具翅的显著的花被管花的基部；浓密的花被管白色短柔毛；副萼缺席。 3 L。 villosa 毛紫薇

Leaves simple, mostly palmately lobed or parted; sepals valvate, epicalyx segments present; stamens 1–5; style basal or sub-basal; flowers usually in corymbose cymes, always bisexual.

单叶，多数掌状浅裂或深裂；镊合状的萼片，副萼片宿存；雄蕊1-5；花柱基部的或近基部；在伞房状聚伞花序，总是是阴阳人里的通常的花。

The flower is bisexual, the top gives birth to raceme, the 6-10 that have a flower, collectivity does not have wool, have short peduncular, shape of calyx canister bell, olive, sepal brim has pointed fretsaw to age, leaf pours egg form, white, long make an appointment with 1.5cm, tip is blunt, base the ministry has short claw, staminal 15-20, every 3-4 be born one bundle at flower disc brim, carpel 5, style is detached.

花两性，顶生总状花序，具花6-10条，全体无毛，有短花梗，萼筒钟状，黄绿色，萼片边缘有尖细锯齿，花瓣倒卵形，白色，长约1.5cm，先端钝，基部有短爪，雄蕊15-20枚，每3-4枚一束生于花盘边缘，心皮5，花柱分离。

Fucose composed of 40% the total carbohydrate with lesser but approximately equal amount of galactose, glucosamine, and galactosamine present.

对糖萼的糖化学组份分析表明糖萼是由40％的岩藻及大致等量的半乳糖，氨基葡萄糖和氨基半乳糖组成。

Eichhornia crassipes and Hosta ventricosa is used as experimental material to study Cd stress on the two plants growth, chlorophyll content, MDA and root peroxidase activity and other physiological indicators to investigate the effect of Cd on the toxic effect of higher plants,with a view to Cd pollution Phytoremediation providing a theoretical basis.

以凤眼莲和紫萼玉簪为实验材料，研究镉胁迫对凤眼莲和紫萼玉簪的生长、叶绿素含量、丙二醛含量及根系过氧化物酶活性等生理指标的影响，探讨镉对高等植物的毒害效应，以期为重金属镉污染的植物修复技术提供理论依据。

In all treatments, removal rate ofphosphorus and phosphorus accumulation in vivo of Eichharnia crassipes are greater than Hostaventricosa. The results showed that in phosphorus pollution water, the repair results of Eichhorniacrassipes is better than Hosta ventricosa.

在各处理中凤眼莲对磷的去除率以及体内磷的累积量都要大于紫萼玉簪，说明凤眼莲对磷污染水体的修复效果好于紫萼玉簪。

In nitrogen and phosphorus mixed pollution water, in thewater that the concentration of nitrogen is 21mg/L and the concentration of phosphorus is155mg/L, Eichharnia crassipes and Hosta ventricosa can grow normally. In the water that theconcentration of nitrogen is 210mg/L and the concentration of phosphorus is 31mg/L, thephysiological indicators of Hosta ventricosa is good but the physiological indicators of Eichhomiacrassipes is worse than the other treatment and the root of Eichharnia crassipes was rot when itwas planted in the 7th day, and on the 11th day the plants wilt symptoms, it noted that thistreatment affected the growth of Eichharnia crassipes.

在氮磷复合污染的水体中，凤眼莲和紫萼玉簪在氮浓度21mg／L，磷浓度155mg／L水体中都能够正常生长，而在氮浓度210mg／L，磷浓度31mg／L水体中，紫萼玉簪生长正常，而凤眼莲的生理指标比在其它处理中要差，并且凤眼莲在种植的第7天出现根部腐烂，11天时植株枯萎的症状，说明氮浓度210mg／L，磷浓度31mg／L复合污染在一定程度上影响植物的正常生长。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
