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。

The artificial flower doctrine that with German botanist Engele is a delegate thinks the flower of angiosperm and gymnospermous ball flower agree completely, every stamen and carpel, be equivalent to a male flower that degrades extremely and female flower respectively, consequently tentative idea angiosperm is to come from child plant hemp is yellow kind yellow Ephedra Campylopoda of curved handle hemp, following plan institute are shown, in this tentative idea, the bud of male flower piece turn into perianth, the bud of female flower piece turn into carpel, the small bud of every male flower piece after disappearing, remain a stamen only, female flower small bud piece ovule is remained only after disappearing, ministry of foundations of move unripe Yu Zi.

以德国植物学家恩格勒为代表的假花学说认为被子植物的花和裸子植物的球花完全一致,每个雄蕊和心皮,分别相当于1个极端退化的雄花和雌花,因而设想被子植物是来自棵子植物麻黄类的弯柄麻黄Ephedra campylopoda,如下图所示,在这个设想里,雄花的苞片变为花被,雌花的苞片变为心皮,每个雄花的小苞片消失后,只剩下一个雄蕊,雌花小苞片消失后只剩下胚珠,着生于子房基部。

During the development of process of male flower,the stamen differentiatedconstantly,but the pistillate primordium degenerated and there was noremain of pistillate primordium in mature male flowers.During thedevelopment process of female flower,the pistillate primordiumdifferentiated constantly,the development of stamen stopped but didn′tdegenerated.

雄花发育过程中雄蕊原基不断分化而雌蕊原基则退化,成熟的雄花中无雌蕊原基痕迹;雌花发育过程中雌蕊原基不断分化,雄蕊的发育停止但不退化,成熟的雌花中仍可见到发育中途停止的雄蕊。

The floral primordium is initially circular, along with the edge of which slight concaves occur. The outmost whorl of tepal primordia arises as a result of apical meristem division and the floral primordium then is in the shape of triangle. Two further whorls of tepal primordia arise in spiral acropetal sequence and are alternately arranged. When the innermost whorl of tepal primordia is at the late developmental stage, the foremost stamen primordia arise almost simultaneously in spiral acropetal succession and all of the stamen primordia are ultimately arranged in a triangle-cone form. Late in stamen primordium development, carpel primordia arise as same as the young stamen primordia and grow laterally. Grooves are present on the adaxial side of each carpel and develop into ventral sutures gradually closing up.

观光木的花原基最初为近圆形,随着顶端分生组织的活动,花原基边缘处出现浅凹,形成第一轮花被片原基,此时,花原基呈三角形排列,后两轮花被片原基依次发生,与前一轮互生;在内轮花被片发生的后期,最初几枚雄蕊原基几乎同时出现,呈螺旋状向顶发生,最后排列成三角圆锥状;雄蕊原基发育后期,心皮原基开始发育,形状与发育初期的雄蕊原基相似,随后心皮原基进行侧向生长,在近轴面出现浅凹,进而发育为凹槽,形成腹缝线,最后腹缝线完全愈合。
