All characters that have been used to delimit more narrowly defined species in other treatments of Chinese Clethra exhibit a strongly continuous pattern of variation from west to east across the range of the species in China (i.e., leaf size and shape, the number of secondary veins on each side of the midvein, anther size and shape); they also exhibit geographically correlated or seemingly random patterns, but without correlated gaps in character states among any two or more characters (i.e., style pubescence, corolla abaxial surface, stamen exsertion).
用来界定更狭窄定义的中国的Clethra的其它种的全部特征,从中国种的分布区的西部到东部,展示了一种强烈的连续变异的样式(如,叶大小和形状,中脉每边次脉的数目,花药的大小和形状);他们还展示出地理分布的相关或好像随机的样式,但是在任何2或更多特征状态间没有相关的特征间隔(如,花柱被短柔毛,花冠背面、雄蕊伸出)。叶大小与形状,在中脉,花药大小与形状的每边次脉的数量;也的他们展览好象地理上有相互关联或随机模式,但是没有有相互关联特征差距在任何2 特征或更多中说明即,花柱短柔毛,花冠背面,雄蕊exsertion。

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。

Historically, plants of this affinity with stamen number equal to sepal number were Ludwigia , and those with stamens twice as many as sepals were Jussiaea , but Raven and others demonstrated reticulate variation in this character, and treated the two groups as a single genus.
历史上,常具有与萼片数相同的雄蕊数的植株为 Ludwigia的,而雄蕊数为萼片的2倍的是Jussiaea的,但 Raven和其它人证明这一特征成网状式的变异,并且把这两个类群归入同一属内。

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。
