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。
-
A structure which appears to be simple, though actually derived from the fusion of separate structures, as a pistil which appears to be composed of a single carpel, though actually composed of two or more carpels.
假单基数的 Pseudomonomerous 实由离生结构愈合而成却看似单一的结构,如看似单心皮的雌蕊,实为两个或多个心皮组成。

Fruit a loculicidal capsule or a schizocarp, separating into individual mericarps, rarely berrylike when mature; carpels sometimes with an endoglossum a crosswise projection from back wall of carpel to make it almost completely septate.
果为室背开裂蒴果或者分果,分裂成数个果瓣,很少成熟的时候为浆果状;心皮有时有endoglossum来自心皮的背面壁的十字状凸出物预测使它几乎完全具隔。

The molecular phylogeny of Alismatidae based on analysis of chloroplast rbcL gene sequence data serves as a framework with which to evaluate character evolution with respect to the derivation of apocarpy in the group.
本文基於rbcL基因序列资料构建了泽泻亚纲的系统发育关系,依据此系统发育关系为框架,讨论了泽泻亚纲不同心皮的起源与演化,尤其是离生心皮的起源与演化。

Fruit a ± completely syncarpous 4-loculed drupaceous berry [or grading to subapocarpous with 4 basally connate drupaceous berries]; exocarp ± fleshy or dry; mesocarp, if evident, spongy-crustaceous or ± woody; endocarp cartilaginous.
果为多少完全合心皮的4室的具核果状浆果 [或逐渐变为近离心皮的具4室基部合生的具核果状浆果];外果皮多少肉质或干燥;中果皮,如果明显,为海绵状壳质或者多少木质;内果皮软骨质。
