花被

Stamens 6, rarely 3, 4, or 8, inserted opposite perianth segments; filaments free or adnate to perianth, rarely connate into a corona; anthers usually 2-loculed, basifixed or dorsifixed and versatile, introrse, latrorse, or extrorse, dehiscing usually by vertical slits.

雄蕊6，很少3，4，或者8，与花被片对生；花丝离生，或者与花被贴生，很少合生成一副花冠；花药通常2室，基着或者背着和丁字着，内向，侧向，或者外向纵裂，通常以垂直裂缝开裂。

Stamens 6, free or basally adnate to perianth, slightly shorter than perianth; filaments filiform or widened in proximal part; anthers small, suborbicular to reniform, basifixed, extrorse, with confluent locules, dehiscing transversely by valves.

雄蕊6，离生或基部帖生于花被，稍短于花被；花丝丝状或加宽在下部；小的花药，近圆形到肾形，基着，外向，具愈合的室，以裂爿横向开裂。

Flowers in cymules, pedicellate; perianth campanulate, cupular, or saucer-shaped, lobes connate at base; stamens 6, inserted at base of perianth lobes or in throat of tube, anthers dorsifixed, introrse.

花生于小聚伞花序，有花梗；花被钟状，杯状或者茶托状，裂片在基部合生；雄蕊6，着生的在花被基部裂片或在筒部的喉，花药背着，内向。

Stamens as many as tepals and opposite these, rarely fewer than tepals; filaments free, united into a cup at base or ± entirely into a tube, filament lobes present or absent, pseudostaminodes present or absent; anthers (1- or)2-loculed, dorsifixed, introrsely dehiscent.

雄蕊和花被片同数并且大多对生，很少比花被片更少；花丝分离，或者基部合生成杯状或全部合生成一个管状，花丝裂片有或无，有或无假退化雄蕊；花药(1-)2室，背生，内侧开裂。

Flowers bisexual; pedicel articulate. Perianth usually white; tepals 6, free, 3--7-veined, persistent or marcescent.

花两性 花梗有节花被通常白色；花被片6，离生，3-7脉，持久或者凋而不落。

Was observed by means of light microscope and scanning electronic microscope, the structures were compared between perianth and leaf in details, and some quantitative features in leaves and perianths were measured to explore structure base of aroma production, emission pattern and sites in Michelia alba DC..

花开放过程中花被片结构的变化进行了观察，并与成熟叶片的结构特征进行了比较，对白兰成熟花被片与成熟叶片的一些数量特征进行了测量，探讨了白兰花香气形成、挥发部位及挥发途径的结构基础。

Leaves papery; perianth pinkish or white, tepals 2-3.5 mm; styles 3, free.

叶纸质；花被带粉红色或白色，花被片2-3.5毫米；花柱3，离生； 67

Female flowers: perianth lobes free or connate, usually enlarged in fruit and persistent, occasionally absent; staminodes scarious, opposite to the perianth lobes, or absent.

雌花：花被裂片离生或合生，通常在果期扩大并宿存，偶尔无；退化雄蕊干膜质，与花被裂片对生，或者无。

Leaves 0.5--1 mm wide, semiterete; perianth segments 6--9 mm; filaments 2/3--3/4 as long as perianth segments, inner ones wider than outer.

叶0.5 --1毫米宽，半圆柱形；花被片6 --9毫米；花丝 2/3 --3/4的倍于花被片，比外部宽的内部的。

Secondly, according to the stem and leaf anatomy, leaf epidermis, pollen morphology and floral development, it is found that there are no close relations between Acorus and Typhales, especially in the aspect of floral development. In the course of floral development of A. calamus, neither bracteloe primordium nor common primordium occurs in the whole course. Early development of the flower is strongly unidirectional. Three shield carpels develop into a pistil. In Sparganium fallax, each female flower has a bracteole. The bracteole primordium and the floral primordium originate from a complex structure. A single saccate carpel develops into a pistil. In staminate flowers, petal and stamen primordia initiate spirally.

菖蒲属与香蒲目的茎叶解剖特征、叶表皮特征、花粉特征及花器官发生特点等亦存在着明显区别，特别是花器官发生特点差异尤为显著，如菖蒲属花器官发生过程中，没有苞片原基，也不存在任何形式的复合原基，花被与雄蕊原基均以单向性方式发生，雌蕊由3心皮发育而成，具有&盾状心皮&的特点等，黑三棱属则有苞片原基发生，且苞片原基与雌花原基起源于共同的复合结构，雄花的花被原基和雄蕊原基均以螺旋状方式发生，雌蕊由单心皮发育而成，未发现有2或3个心皮原基或其痕迹的现象，体现出&囊状心皮&的特点。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
